How roaming works

Standard x402, no SDK required. Any client that speaks HTTP 402 can pay.

01 · HTTP 402

Call any route

GET or POST with no payment. The gateway answers with the exact x402 challenge: USDC price, merchant address, fee payer.

02 · USDC ON ALGORAND

Settle once

Your client signs, GoPlausible verifies and settles on Algorand. Every route shares one merchant address.

03 · DUAL RECEIPTS

Fulfilled cross-chain

Roam402 pays the origin on its home chain and streams the response back with receipts from both chains. If the origin fails, you are never charged.

$ curl https://roam402.com/trust?domain=blockrun.ai HTTP/1.1 402 Payment Required # x402 challenge: price, payTo, feePayer $ curl https://roam402.com/trust?domain=blockrun.ai -H "X-PAYMENT: <signed>" HTTP/1.1 200 OK # body + Algorand receipt + origin receipt
Census-vetted catalog

Tiers, prices, and liveness come from the Agents-Trust census of $45M+ in settlement, not a directory scrape.

Precheck before paying

/precheck and /trust vet seller identity, tier, and liveness before any funds move.

One merchant payTo

All 2355 routes settle to a single Algorand address, so treasury audit stays trivial.

A catalog that is alive

These rows render from the same worker that serves the 402s. The machine-readable catalog is free at /catalog, and down routes refuse before payment.
