How x402all works

x402all is a discovery index. We aggregate public x402 facilitator feeds, enrich each endpoint with agent-readable summaries, and serve per-resource JSON twins alongside the HTML pages. Execution and wallet custody belong to the agent client.

1

Discover

Search by intent, category, or chain. Filter on per-call USDC price and trust tier.

2

Inspect

Review the price, network, pay-to address, request/response hints, and LLM-generated use-case summary on the detail page.

3

Run on AXON

Push any endpoint into your AXON wallet. AXON signs the X-PAYMENT envelope, handles USDC settlement, and streams the response back to your agent.

Do you serve x402 endpoints?

If your API returns HTTP 402 Payment Required with a USDC settlement envelope, register your origin so agent clients can discover it with verified metadata.
