# Open Databases Integration for Materials Design

The Open Databases Integration for Materials Design (OPTIMADE) makes the materials databases interoperational by developing a common REST API.

## APIs

1 public API with a stored document.
Each links to its markdown overview; the same address with
`/llms.txt` in place of `.md` lists its operations.
Changes across these APIs: https://skmtc.dev/materials-consortia/feed.md

- [OPTIMADE API](https://skmtc.dev/materials-consortia/apis/optimade-api.md): Materials science: query crystal structures, references, files and links from interoperable materials databases
