REST API

Introduction

The Zenodo REST API currently supports:

  • Deposit — upload and publishing of research outputs (identical to functionality available in the user interface).
  • Records — search published records.
  • Files — download/upload of files.

Check out the Quickstart guide for an example on how to programmatically upload and publish your research outputs.

The following REST APIs are currently in testing before we launch them in beta with full documentation:

  • Communities - search communities.
  • Funders — search for funders.
  • Grants — search for grants.
  • Licenses — search for licenses.

You can have a sneak peek at the APIs in test from our root endpoint: https://zenodo.org/api/

Quickstart - Upload

This short guide will give a quick overview of how to upload and publish on Zenodo, and will be using either:

  1. Python together with the Requests package.
  2. Javascript together with the axios package.
# Install 'requests' module for python
pip install requests

# Install 'axios' module for nodejs 
npm install axios
  • First, make sure you have the Requests module installed for python or axios for nodeJS:
python
# Python 3.6.5
# [GCC 4.8.1] on linux2
# Type "help", "copyright", "credits" or "license" for more information.
node
// Welcome to Node.js v14.19.0.
// Type ".help" for more information.
  • Next, fire up a command prompt:
import requests
const axios = require('axios');
  • Import the module to handle requests:
import requests
r = requests.get("https://zenodo.org/api/deposit/depositions")
r.status_code
# 401
r.json()
const axios = require('axios');

axios.get("https://zenodo.org/api/deposit/depositions").then(response => {
  console.log(response);
}).catch(error => {
  console.log(error.response.data);
});
{
  "message": "The server could not verify that you are authorized to access
  the URL requested. You either supplied the wrong credentials (e.g. a bad
  password), or your browser doesn't understand how to supply the credentials
  required.",
  "status": 401
}
  • We will try to access the API without an authentication token:
  • All API access requires an access token, so create one.
ACCESS_TOKEN = 'ChangeMe'
r = requests.get('https://zenodo.org/api/deposit/depositions',
                  params={'access_token': ACCESS_TOKEN})
r.status_code
# 200
r.json()
# []
const ACCESS_TOKEN = 'ChangeMe'

const requestParams = {
  params: {
    'access_token': ACCESS_TOKEN
  }
}
axios.get("https://zenodo.org/api/deposit/depositions", requestParams).then(response => {
  console.log(response.status);
  // > 200
  console.log(response.data);  
  // > []
}).catch(error => {
  console.log(error.response.data);
});
  • Let’s try again (replace ACCESS_TOKEN with your newly created personal access token):
headers = {"Content-Type": "application/json"}
params = {'access_token': ACCESS_TOKEN}
r = requests.post('https://sandbox.zenodo.org/api/deposit/depositions',
                   params=params,
                   json={},
                   '''
                   Headers are not necessary here since "requests" automatically
                   adds "Content-Type: application/json", because we're using
                   the "json=" keyword argument
                   headers=headers, 
                   '''
                   headers=headers)
r.status_code
# 201
r.json()
const requestParams = {
  params: {
    'access_token': ACCESS_TOKEN
  },
  headers : {
    "Content-Type": "application/json"
  }
}

axios.post("https://zenodo.org/api/deposit/depositions", requestParams).then(response => {
  console.log(response.status);
  // 201
  console.log(response.data);  
}).catch(error => {
  console.log(error.response.data);
});

    "state": "unsubmitted",
    "submitted": false,
    "title": ""
}
  • Next, let’s create a new empty upload:
  • Now, let’s upload a new file. We have recently released a new API, which is significantly more perfomant and supports much larger file sizes. While the older API supports 100MB per file, the new one has a limit of 50GB total in the record (and any given file), and up to 100 files in the record.
bucket_url = r.json()["links"]["bucket"]
curl https://zenodo.org/api/deposit/depositions/222761?access_token=$ACCESS_TOKEN
{ ...
  "links": {
    "bucket": "https://zenodo.org/api/files/568377dd-daf8-4235-85e1-a56011ad454b",
    ...,
  },
... }
  • To use the new files API we will do a PUT request to the bucket link. The bucket is a folder-like object storing the files of our record. Our bucket URL will look like this: https://zenodo.org/api/files/568377dd-daf8-4235-85e1-a56011ad454b and can be found under the links key in our records metadata.
''' 
This will stream the file located in '/path/to/your/file.dat' and store it in our bucket.
The uploaded file will be named according to the last argument in the upload URL,
'file.dat' in our case. 
'''
$ curl --upload-file /path/to/your/file.dat https://zenodo.org/api/files/568377dd-daf8-4235-85e1-a56011ad454b/file.dat?access_token=$ACCES_TOKEN
{ ... }
''' New API '''
filename = "my-file.zip"
path = "/path/to/%s" % filename

''' 
The target URL is a combination of the bucket link with the desired filename
seperated by a slash.
'''
with open(path, "rb") as fp:
    r = requests.put(
        "%s/%s" % (bucket_url, filename),
        data=fp,
        params=params,
    )
r.json()
const fs = require('fs');
const axios = require('axios');

const filePath = '<FILE_PATH>'; // Replace with file path
const bucketURL = '<BUCKET_URL>'; // Replace with bucket url
const fileName = '<FILE_NAME>'; // Replace with file name
const token = 'TOKEN'; // Replace with token value

// Create a form
const form = new FormData();

// Read file as a stream
const stream = fs.createReadStream(filePath);
form.append('file', stream);

// Create request
let url = `${bucketURL}/${fileName}`;

let params = { 'access_token': token }

let headers = {
    'Content-type': 'application/zip'

const requestConfig = {
    data: {
      name: fileName,

         'upload_type': 'poster',
         'description': 'This is my first upload',

                  headers=headers)
r.status_code
# 200
// Old API documentation not available for javascript / NodeJS
  • Last thing missing, is just to add some metadata:
r = requests.post('https://zenodo.org/api/deposit/depositions/%s/actions/publish' % deposition_id,
                      params={'access_token': ACCESS_TOKEN} )
r.status_code
# 202
// Old API documentation not available for javascript / NodeJS
  • And we’re ready to publish:

Testing

We provide a sandbox environment where you can test your API integration during development. The sandbox environment is available at https://sandbox.zenodo.org.

Please note the following:

  • The sandbox environment can be cleaned at anytime.
  • The sandbox environment requires a separate registration and separate access token from the ones used on https://zenodo.org.
  • The sandbox environment will issue test DOIs using the 10.5072 prefix instead of Zenodo’s normal prefix (10.5281).

Versioning

The REST API is versioned. We strive not to make backward incompatible changes to the API, but if we do, we release a new version. Changes to the API are documented on this page, and advance notification is given on our Twitter account.

Authentication

All API requests must be authenticated and over HTTPS. Any request over plain HTTP will fail. We support authentication with via OAuth 2.0.

Creating a personal access token

  1. Register for a Zenodo account if you don’t already have one.
  2. Go to your Applications, to create a new token.
  3. Select the OAuth scopes you need (for the quick start tutorial you need deposit:write and deposit:actions).

Using access tokens

An access token must be included in all requests as either:

GET /api/deposit/depositions?access_token=<ACCESS_TOKEN>
  • an URL parameter (named access_token):
GET /api/deposit/depositions
Authorization: Bearer <ACCESS_TOKEN>
  • or as HTTP request header (Authorization):

Scopes

Scopes assigns permissions to your access token to limit access to data and actions in Zenodo. The following scopes exist:

Name Description
deposit:write Grants write access to depositions, but does not allow publishing the upload.
deposit:actions Grants access to publish, edit and discard edits for depositions.

Requests

The base URL of the API is https://zenodo.org/api/.

All POST and PUT request bodies must be JSON encoded, and must have content type of application/json unless specified otherwise in the specific resource (e.g. in the case of file uploads). The API will return a 415 error (see HTTP status codes and error responses) if the wrong content type is provided.

Responses

{
    "field1": "value",
    "...": "..."
}

All response bodies are JSON encoded (UTF-8 encoded). A single resource is represented as a JSON object:

[
    {
        "field1": "value",
        "...": "..."
    }
    "..."
]

A collection of resources is represented as a JSON array of objects:

YYYY-MM-DDTHH:MM:SS+00:00

Timestamps are in UTC and formatted according to ISO 8601:

HTTP status codes

We use the following HTTP status codes to indicate success or failure of a request.

Code Name Description
200 OK Request succeeded. Response included. Usually sent for GET/PUT/PATCH requests.
201 Created Request succeeded. Response included. Usually sent for POST requests.
202 Accepted Request succeeded. Response included. Usually sent for POST requests, where background processing is needed to fulfill the request.
204 No Content Request succeeded. No response included. Usually sent for DELETE requests.
400 Bad Request Request failed. Error response included.
401 Unauthorized Request failed, due to an invalid access token. Error response included.
403 Forbidden Request failed, due to missing authorization (e.g. deleting an already submitted upload or missing scopes for your access token). Error response included.
404 Not Found Request failed, due to the resource not being found. Error response included.
405 Method Not Allowed Request failed, due to unsupported HTTP method. Error response included.
409 Conflict Request failed, due to the current state of the resource (e.g. edit a deopsition which is not fully integrated). Error response included.
415 Unsupported Media Type Request failed, due to missing or invalid request header Content-Type. Error response included.
429 Too Many Requests Request failed, due to rate limiting. Error response included.
500 Internal Server Error Request failed, due to an internal server error. Error response NOT included. Don’t worry, Zenodo admins have been notified and will be dealing with the problem ASAP.

Errors

Error responses for 400 series errors (e.g. 400, 401, 403, …) are returned as a JSON object with two attributes message and status (HTTP status code), and possibly an attribute errors with a list of more detailed errors.

{
    "message": "Deposition not found",
    "status": 404
}

For more complex errors, we include the attribute errors, a JSON array of objects, each with the attributes message (with a human-readable explanation of the error), and possibly field (with the “path” to field that contains the error).

Example of an error message with detailed errors:

{
    "message": "Validation error",
    "status": 400,
    "errors": [
        {"field": "metadata.access_right", "message": "Not a valid choice"},
        {"field": "metadata.creators.0.name", "message": "Name is required."},
        {"field": "non_existent", "message": "Unknown field name."}
    ]
}

New version

Create a new version of a deposition.

This action will create a new deposit, which will be a snapshot of the current resouce, inheriting the metadata as well as snapshot of files. The new version deposit will have a state similar to a new, unpublished deposit, most importantly its files will be modifiable as for a new deposit.

Only one unpublished new version deposit can be available at any moment, i.e.: calling new version action multiple times will have no effect, as long as the resulting new version deposit from the first call is not published or deleted.

NOTES: - The response body of this action is NOT the new version deposit, but the original resource. The new version deposition can be accessed through the "latest_draft" under "links" in the response body. - The id used to create this new version has to be the id of the latest version. It is not possible to use the global id that references all the versions.

REST API initial release candidate.

OAI-PMH

Zenodo allows you to harvest our entire repository via the Open Archives Initiative Protocol for Metadata Harvesting (OAI- PMH). OAI-PMH is a widely used protocol for harvesting metadata and most popular repository software provide support for this protocol.

All metadata is licensed under Creative Commons Zero, while the data files may be either open access and subject to a license described in the metadata or closed access and not available for download.

Base URL

Our OAI-PMH base endpoint is at https://zenodo.org/oai2d.

Installing prerequisites for our example

For this example, we are going to be using Sickle since it simplifies our workflow and supports XML parsing.

# Install the Sickle package using pip
pip install Sickle
'''Import Sickle and initialize the client by passing the base URL'''
from sickle import Sickle
sickle = Sickle('https://zenodo.org/oai2d')

Get information about the OAI-PMH API

To get some general information about the OAI-PMH capabilities we can use the Identify verb.

'''Get information on the OAI-PMH API by using "Identify"'''
info = sickle.Identify()
info.granularity
# 'YYYY-MM-DDThh:mm:ssZ'

info.earliestDatestamp
# '2014-02-03T14:41:33Z'

Resumption tokens

Resumption tokens are only valid for 2 minutes. In case a token expired, you will receive a 422 Unprocessable Entity HTTP error.

Rate limit

The OAI-PMH API is rated limited like the REST API - i.e. you will receive a 429 Too Many Requests HTTP error if you exceed the limit. For more information please take a look at the rate limiting documentation.

Metadata formats

To list the available records metadata formats we can use ListMetadataFormats.

'''Metadata for each record is available in several formats'''
metadataFormats = sickle.ListMetadataFormats()
list(metadataFormats)
# [<MetadataFormat marcxml>, <MetadataFormat oai_datacite4>, ...]

Available metadata formats

oai_datacite

OAI DataCite (latest schema version) — This metadata format has been specifically established for the dissemination of DataCite records using OAI-PMH. In addition to the original DataCite metadata, this format contains several other elements describing the version of the metadata, whether it is of reference quality, and the registering datacentre. For more information about this format and its schema please see the DataCite OAI schema website.

This metadata format will always deliver metadata according to the latest available DataCite schema version.

See example

datacite

DataCite (latest version) — This metadata format contains only the original DataCite metadata without additions or alterations according to the latest DataCite schema. Please note that this format is not OAI-PMH version 2.0 compliant.

See example

oai_dc

Dublin Core — only minimal metadata is included in this format. The format is exported according to the OpenAIRE Guidelines.

See example

dcat

DCAT — export format based on the DCAT Application Profile for data portals in Europe (DCAT-AP). The format is produced from the DataCite export format using the DataCite-to-DCAT-AP XSLT. This is the only OAI-PMH metadata format that currently exposes direct links to each record’s files content, via the dcat:Distribution elements.

See example

marc21

MARC21 — export format primarily supported for legacy reasons. Please consider using one of the other export formats as we may discontinue support for MARC21.

See example

Sets

We support both harvesting of the entire repository as well as selective harvesting of communities.

Entire repository

To harvest the entire repository, entirely skip the set parameter (you still need to pass the required metadataPrefix parameter).

See example

''' Harvest the entire repository '''
records = sickle.ListRecords(metadataPrefix='oai_dc')
record = records.next()
# <Record oai:zenodo.org:3442216>

Selective harvesting

user-<identifier>

Community sets — allows selective harvesting of specific communities. Replace <identifier> with the community identifier. Alternatively each community provides a direct harvesting API link on their front-page, which includes the correct community identifier.

See example

''' Fetch a couple of records from the OAI Set of the "cfa" community '''
records = sickle.ListRecords(metadataPrefix='oai_dc', set='user-cfa')
record = records.next()

''' To inspect on what sets a record is in '''
record.header.setSpecs
# ['openaire_data', 'user-cfa']

Harvesting with a different metadata format

There is also the possibility of using different metadata formats. For that, we only need to replace the metadataPrefix argument.

See example

''' Community harvest using "oai_datacite" metadata format '''
records = sickle.ListRecords(metadataPrefix='oai_datacite', set='user-cfa')
record = records.next()

''' Retrieving metadata from the record '''
record.metadata
# {
#    "title": ["Computing and Using Metrics in ADS"],
#    "creatorName": ["Henneken, Edwin"],
#    "identifier": ["10.5281/zenodo.10897"],
#    ...
# }

Harvesting with multiple filters

Using multiple filters to harvest records enables a higher level of granularity, allowing us to retrieve specific groups of records.

See example

''' Selecting harvesting using "from" '''
records = sickle.ListRecords(**{
    'metadataPrefix': 'oai_dc',
    'set': 'user-cfa',
    'from': '2019-01-01',
})

records.next()
# <Record oai:zenodo.org:7661>

records.next()
# <Record oai:zenodo.org:6738>

Other questions on harvesting

If you need selective harvesting and your use case is not supported by above sets, you can contact us and we can try create a specific set for you.

Update schedule

Most updates are available immediately, some few updates are only reflected in the OAI sets once an hour.

We automatically extract metadata about your release from GitHub APIs. For example, the authors are determined from the repository’s contributor statistics. To overwrite some of the default metadata that would come from a regular GitHub release you can include a .zenodo.json file at the root of your GitHub repository.

The contents of the .zenodo.json file are based on our deposit metadata documentation and can be structurally validated using our legacy deposit JSON Schema.

In the example shown, we add metadata regarding:

  • software authorship and ORCiDs, via the creators field
  • Apache-2.0 licensing, via the license field
  • a custom title, via the title field
  • a related identifier to the software paper, via the related_identifiers field
  • keywords, via the keywords field
  • Zenodo communities, via the communities field
  • funding information, via the grants field

How to verify your “.zenodo.json” file?

After creating your .zenodo.json file you should validate it to make sure that it contains valid JSON. You can use a tool like the JSON Formatter & Validator, or load it via your favorite programming language.

Rate Limiting

For our content and services to be available to everyone we have to make sure that our resources are being distributed fairly. To achieve this, we have rate-limiting measures in place which limit the number of requests users can perform in a time window. Depending on the complexity and load of each request, different endpoints have different limits configured.

Pages Limitations
Global limit for guest users 60 requests per minute, 2000 requests per hour
Global limit for authenticated users 100 requests per minute, 5000 requests per hour
OAI-PMH API harvesting 120 requests per minute
Thumbnails for image records 20 requests per minute

When you are making requests to any of our endpoints, you can inspect the following HTTP response headers for more information of your current rate-limit status:

HTTP header Description
X-RateLimit-Limit Current rate-limit policy, i.e. maximum number of requests per minute
X-RateLimit-Remaining Number of requests remaining in the current rate limit
X-RateLimit-Reset Reset time of the current rate limit
