RESTful API

RESTful APIs provide programmatic access to the ChEBI database, allowing users to seamlessly integrate ChEBI into their applications or perform various computations. These APIs are built on the Representational State Transfer (REST) architecture and can be accessed using any REST API client. As all data in ChEBI is freely accessible to everyone, no authentication or authorization is required for the public APIs. Input parameters and output responses are formatted in JSON, enabling users to perform keyword searches, conduct advanced searches within ChEBI, and retrieve detailed information of an entity.

For further details, please refer to our comprehensive API documentation. Please report any issues or feature requests via GitHub or contact us.

Ontology Lookup Service

The Ontology Lookup Service (OLS) is a repository for biomedical ontologies that aims to provide a single point of access to the latest ontology versions. You can browse the ontologies through the website as well as programmatically via the OLS API. OLS is developed and maintained by the Samples, Phenotypes and Ontologies Team (SPOT) at EMBL-EBI.
