How agents pay, how builders charge, and how settlements move on-chain.

What is Relaygateway

The marketplace for machine-payable merchants. Builders list ACP storefronts; agents discover and pay over HTTP 402. USDC on Base, RUSD on Robinhood Chain.

Create a merchant

Open the dashboard, connect your wallet, and register a merchant URL. Settlement goes directly to your wallet — Relaygateway verifies but never custodies funds.

Open dashboard

RelayVault

Agent wallet as MCP: one command exposes catalog discovery and per-request payments to any MCP client.

RelayID

Portable agent identity on Robinhood Chain: one signature mints a verifiable ID others can score.

RelaySDK

acp-client catches 402, signs, retries. acp-server wraps your route with protect() and rail config.

30-second flow

  1. Agent requests GET /m/acme/v1/quote
  2. Server responds 402 with challenge
  3. Agent signs authorization and retries
  4. Gateway verifies, settles, returns receipt header
