EHRI Data APIs

Overview

The EHRI portal's APIs (application programming interfaces) allow users (researchers, developers, etc) to retrieve EHRI's information in a programmatic fashion. Several APIs are offered, suitable for different purposes:

GraphQL API

The GraphQL API implements Facebook's data query language and provides the means to make highly specific queries of the portal's data with a wider scope than that provided by the search API.

Try the EHRI GraphQL API.

OAI-PMH

EHRI provides an Open Archives Initiative Protocol for Metadata Harvesting endpoint at: https://portal.ehri-project-stage.eu/api/oaipmh .

Try the OAI-PMH interface.

EHRI Datasets

EHRI datasets are dynamically-generated structured data about EHRI's collections and related information, available in JSON, CSV, and TSV formats.
