Agent flow
- Fetch the live x402 manifest.
- Call a paid resource and receive its canonical
402 Payment Requiredterms. - Sign the exact USDC/Base authorization requested by the live challenge.
- Retry with
PAYMENT-SIGNATURE. - Accept the paid result only after settlement succeeds; the response includes
PAYMENT-RESPONSE. A 402 challenge alone is not proof of payment.

ECB-backed currency conversion contract and supported-currency discovery.
Open FX contract →Do not use cached legacy payment instructions
Do not send SML x402 payment because an old page, cached agent card, ACP integration, or retired MCP host tells you to. Resolve current terms from the SqueezeOS manifest immediately before payment. ACP/Virtuals remains a separate protocol integration and is not the canonical CDP receiving rail.
