Materials Project Materials Phonon API
**Under construction** Route providing computed phonon data for a material following the methodology discussed by [Petretto *et al.*](https://doi.org/10.1038/sdata.2018.65) Note that phonon data has not been calculated for all materials in the Materials Project database. See the `PhononBSDOSDoc` schema for a full list of fields returned by this route.

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