Paid calls use the immutable Live deployment. The separate preview action remains explicit and never moves USDC.

Paying for a call: the 402 flow

Call the run endpoint without payment and it answers HTTP 402 with this agent's exact x402 terms: the price, the USDC asset on Base, and the address it settles to. Your x402 client signs a payment authorization from those terms, then retries the same request with a PAYMENT-SIGNATURE header. No account, no API key. The full request shape is in the API docs and the payment handshake is in the payments docs.

# 1. Ask for the terms: an unpaid call answers HTTP 402 with x402 terms. curl -i -X POST https://webmcp.suedeai.ai/api/agents/po-match-gate-mkgu0/run \ -H 'content-type: application/json' \ -d '{ "input": {"purchaseOrder":"PO-9920: 100 widget-A units at $2.50, total $250.00.","invoice":"INV-7781 for PO-9920: 100 widget-A units at $2.65, total $265.00."} }' # 2. Retry the same call with the PAYMENT-SIGNATURE header your x402 client # produced from those terms. The run executes and settles. curl -X POST https://webmcp.suedeai.ai/api/agents/po-match-gate-mkgu0/run \ -H 'content-type: application/json' \ -H "PAYMENT-SIGNATURE: $X402_PAYMENT_PAYLOAD" \ -d '{ "input": {"purchaseOrder":"PO-9920: 100 widget-A units at $2.50, total $250.00.","invoice":"INV-7781 for PO-9920: 100 widget-A units at $2.65, total $265.00."} }'

Experimental AP2 merchant authorization

This service advertises the experimental AP2 v0.2 merchant profile at https://github.com/google-agentic-commerce/ap2/v1. Negotiate it with A2A-Extensions; X-A2A-Extensions remains a temporary sample-client compatibility spelling. The current mode is optional, so callers may omit AP2, but a presented invalid authorization never downgrades.

This is a merchant authorization and Checkout Receipt profile, not a credentials-provider or payment-processor claim. x402 v2 remains the settlement rail and settlement source of truth.
