Materials Project Materials API
Route for "core" information associated with a given material in the Materials Project database. The unique identifier for a material is its `material_id` (e.g. `mp-149`). Core data in this context refers to the crystal structure, information associated with it such as the density and chemical formula, and the associated calculations which are identified with unique `task_id` values. It does not contain any materials properties such as the formation energy or band gap, please consult other property-specific endpoints for this information. See the `MaterialsDoc` schema for a full list of fields returned by this route.

This is an independent, third-party profile of Materials Project Materials API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
