Ouro's shared crystal structure database: Materials Project, Alexandria and GNoME with PBE energies, structures generated on Ouro, and structures people submitted, with Orb v3 energies, MP2020-corrected. Check a CIF's energy above the hull, check whether it is already known, add it if it is new, or get a published material's CIF by id. GNoME and Materials Project's GNoME-derived records are CC BY-NC 4.0 (non-commercial use only), so only these free routes use them.

## Routes

A service is an API; each of its endpoints is a route you can run. Each route's page has a markdown twin with its inputs and parameters.
