Discovery feed
AI agents don't browse a marketplace; they read a feed. Every paid endpoint on x402Fi is published here in the Bazaar-style x402 discovery format, so agents and indexers can find a service, see its price and pay it, with no sign-up.
Feed URL (JSON, for agents and indexers)
https://x402fi.dev/api/discovery/resourcesEach item carries the resource URL, the x402 payment requirements (price, USDG, payTo, network) and metadata such as the payee name.
2 paid endpoints in the feed
| Service | Endpoint | Price | Paid to | Payee name |
|---|---|---|---|---|
| x402Fi demo: paid hello Developer tools | GET/g/demo-quote | $0.01 | 0x837F…1330 | — |
| HoodFi Names: Register a name Data feeds | POST/g/hoodfi-names/register/{name} | Up to $15.00 | 0x64A6…2534contract | hoodfi.402api.eth |
Free endpoints are not part of the paid-resource feed; they are listed on each service's marketplace page.
