Materials Project Materials Electronic Structure API

Routes providing computed electronic structure related data for a material such as band gap and fermi level. Python objects for line-mode band structures, density of states, and fermi surfaces are also available. This data was obtained following the methodology discussed by [Munro *et al.*](https://doi.org/10.1038/s41524-020-00383-7) and [Ganose *et al.*](https://doi.org/10.21105/joss.03089) Note that full band structure, density of states, and fermi surface data has not been calculated for all materials in the Materials Project database. See the `ElectronicStructureDoc` and `FermiDoc` schema for a full list of fields returned by the associated routes.

Materials Project Materials Electronic Structure API is one of 29 APIs that Materials Project publishes on the APIs.io network, described by a machine-readable OpenAPI specification.

Tagged areas include Materials Electronic Structure. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and a getting-started guide.

This API exposes 4 operations across 4 paths, and defines 22 schemas. It is described by OpenAPI 3.1.0, at version 0.86.4rc5.dev1+g77c2c1315.

Requests are made against the base URL https://api.materialsproject.org.

Where this information came from

This is an independent, third-party profile of Materials Project Materials Electronic Structure 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.
