A useful answer before the first request.

If you want the endpoint definitions rather than a walkthrough, start with the API reference and OpenAPI specification. The playground uses a separate fictional dataset for exploring the schema.

For retained data, inspect source health and observed coverage. The guides distinguish the free request allowance from an unrestricted feed, recorded history from a retroactive archive, and a base prop line from sportsbook odds. Those distinctions remain important after your first successful request.

Our field notes contain longer implementation guides and dated reports grounded in stored observations. Automated reports skip stale inputs and do not imply that every upstream change was collected.
