## When to prefer this

Use this endpoint when you need to discover or validate sample cohorts referenced in polygenic score (PGS) research, particularly when building tools that integrate with the PGS Catalog ecosystem or when cross-referencing cohort names from genomics studies.

## Known failure modes

- Empty result set when no cohorts match the query string
- HTTP 402 if payment is not provided or fails
- Malformed JSON if the upstream PGS Catalog API is unavailable
- Timeout or 503 if the PGS Catalog service is down
- Missing or null fields if cohort metadata is incomplete in the source database
