Meta Book Catalog

Full registered-book catalog with class labels and ingest status.

Sister to /v1/meta/source-stack: where source-stack is curated and deep (full integration metadata for each book we've genuinely wired live), this endpoint is breadth-oriented and surfaces every book in the classification registry alongside a live flag indicating whether it's currently producing rows.

Use cases:

• Customer auditing "do you cover sportsbook X?" with one HTTP GET instead of having to read the source-stack and figure out what's missing
• AI agents enumerating coverage for a comparison page
• Operators identifying which scaffolded modules haven't yet been promoted to live ingest

Response shape: { "as_of_iso": "...", "aggregate": { "books_total": N, // every key in classification registry "books_live": N, // subset currently producing rows "books_scaffolded_not_live": N, "by_class": {"us_retail": N, "uk": N, ...}, "by_class_with_live": { "us_retail": {"total": N, "live": N}, ... } }, "books": [ { "key": "fanduel", "class": "us_retail", "title": "FanDuel", // display name from BOOKMAKER_TITLES "live": true, // saw rows in last 24h "rows_24h": N, // 0 if not live "variants": [...], // feeds folded in; absent if just one "variant_of": "unibet" // absent unless this key IS a variant }, ... ] }

rows_24h is credited to the OPERATOR: a book's country-licensed feeds (unibet_se, unibet_ro, ...) count toward the book /odds serves, and variants names them. Two Unibet variants are registered in their own right and keep their own rows; they carry variant_of so counting operators means counting variant_of or key.

Public, no auth, no credits. 5-minute server-side cache so polling is cheap; live counts refresh on a 5-min cadence.
