About x402hub

x402hub is a free, independent developer directory for the x402 agentic-payments protocol. It reads the public Coinbase Bazaar discovery registry and turns every listed service into a page with live pricing and ready-to-run code, so developers and AI agents can find and call pay-per-call APIs without digging through docs.

Why it exists

Explorers and uptime monitors for x402 already exist. What was missing was a place that teaches you to call each service. That is this.

Data & independence

All data comes from the public on-chain registry and is refreshed regularly. x402hub is not affiliated with Coinbase or the x402 Foundation. Listings are informational; verify pricing and terms against each service's own 402 response before sending funds.

Support it

The hub is free. If it saved you time, a USDC tip on Base keeps it maintained:

Query this registry programmatically. Every service here is searchable through the x402hub API, an x402-payable endpoint your agents call and pay per request in USDC.
