How listing works

1
Open a pull request
Add a manifest under catalog/providers/<you>/ in relaygrid/catalog: endpoints, pricing, auth, and the field mapping to a capability schema.
2
Automated checks
CI validates the manifest against the capability's Zod schema and calls your sandbox with 50 fixture records.
3
Benchmark run
We run the labeled benchmark set for the capability (2,000 records) and compute fill, accuracy and latency.
4
Review and listing
Identity, terms and data handling review for the Verified badge. Merge publishes the endpoint in the next catalog snapshot.
