Filter by what you need and pull what fits.
Sleeper
Read fantasy league state from the Sleeper platform's public read-only API — no key, no OAuth, no write surface. Resolve a username to a user ID, list leagues and drafts, and read a league in depth: settings and scoring, rosters with owners joined and standings derived, weekly matchups paired head to head, the transaction log, traded picks, playoff brackets, the draft board, and league-wide add/drop trends. Player IDs are resolved to names from a locally cached catalogue, and a missing record (which Sleeper reports as HTTP 200 with a null body) fails loudly instead of reading as empty.
Doc Fact Checker
Fact-check one Markdown document through a provider-neutral, read-only adapter. Kiro CLI is the default provider; Claude CLI is supported when explicitly selected. Repository and optional web capabilities are recorded separately, with no provider fallback.
