Nobel Prize vs Onyx Bazaar

The official Nobel Prize API serves structured, keyless JSON on every laureate, prize category, and award year back to 1901, including prize amounts (nominal and inflation-adjusted) and links between related records. A live query against api.nobelprize.org/2.1/nobelPrizes needs no key and returns a wildcard Access-Control-Allow-Origin header, so it's directly callable from browser code.

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.
