• cc0pedia

  The agentic read API over cc0pedia — the largest machine-readable CC0 database (1,100+ entries: public-domain creators, collections, works). Pay $0.01 USDC per lookup; get ONE entry resolved from a free-text query: provenance, creator, license, on-chain pointers (collection contract addresses / chains / OpenSea), and the full CC0 body.

  Parameters:

  • query (required) — string — Name or slug of the CC0 creator, collection, or work to look up (e.g. 'sartoshi', 'mfers', 'xcopy'). Resolved by exact slug → id → fuzzy title. Browse at https://cc0.company/cc0pedia.
