About TIMDEX Discovery API

TIMDEX is a free discovery API into collections at MIT Libraries.

We currently provide searching of records in MIT Libraries catalog, DSpace@MIT, and MIT ArchivesSpace.

Access is via a GraphQL endpoint by posting to https://timdex.mit.edu/graphql. We recommend starting by exploring our interactive GraphQL playground, or you can look through our developer documentation for how-to guides, API reference, and more.

Example query to use in the playground or your own app:

{
  search(searchterm: "learn graphql") {
    records {
      title
      sourceLink
      summary
    }
  }
}

Jumpstart this example query in the Playground

Additional examples and a tutorial on how to use this GraphQL API will be available soon.

Talk to us!

Feedback is welcome via timdex@mit.edu.

Bug reports via the Github repository would be great.

REST API retired

Our original REST API was deprecated and then retired in early 2023. The replacement GraphQL API can search more data and has features not found in the origial API. If you need help migrating from REST to GraphQL please let us know.
