Materials Project Materials Provenance API is one of 29 APIs that [Materials Project](https://apis.io/providers/materials-project/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Materials Provenance. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and a getting-started guide.

Route providing provenance data for a material such as whether it is theoretical, its associated ICSD entries, and relevant references in literature. Note that provenance data may not be available for all materials in the Materials Project database. See the `ProvenanceDoc` schema for a full list of fields returned by this route.
