Onyx Bazaar vs Open Data Minneapolis
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.
Open Data Minneapolis is the city's ArcGIS Hub portal, publishing GIS layers and non-spatial datasets — from 311 service requests to crime incidents — as a standard Esri Hub site. Its DCAT-US JSON feed and Hub search API expose the full catalogue for machine consumption at no cost and without a key.
