Archive.org vs Onyx Bazaar
The Internet Archive's Advanced Search and Metadata APIs let you query and pull structured records for its 99+ million digitized books, web captures, audio, video, and software items. Reads are keyless for both the search endpoint (archive.org/advancedsearch.php) and per-item metadata (archive.org/metadata/{identifier}), returning JSON, XML, or CSV depending on the requested output format.
Onyx Bazaar is a public leaderboard of x402 pay-per-call HTTP services on Base, Solana, and other chains, refreshed every 15 minutes from Coinbase's CDP discovery API. It ranks listed endpoints by call volume, unique payers, price, and recency, with views for cheapest, newest, and highest-quality services. A keyless JSON endpoint (/bazaar.json) mirrors the same leaderboard data shown on the page for agents that want to query it directly.
