Materials Project Materials Tasks 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 Tasks. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and a getting-started guide.

Route for "core" information associated with a given calculation in the Materials Project database. Multiple calculations can ultimately be associated with a unique material, and are the source of its reported properties. The unique identifier for a calculation is its `task_id`. Note that the `material_id` chosen for a given material is sourced from one of the `task_id` values associated with it. Core data in this context refers to calculation quantities such as parsed input and output data (e.g. VASP input flags, atomic forces, structures) and runtime statistics. See the `TaskDoc` schema for a full list of fields returned by this route.
