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://agents.suedeai.ai/api/agents/5638e477-71a9-4fea-8ef6-8570a7962e91/run \
-H 'content-type: application/json' \
-d '{ "input": {"url":"your url here"} }'
# 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://agents.suedeai.ai/api/agents/5638e477-71a9-4fea-8ef6-8570a7962e91/run \
-H 'content-type: application/json' \
-H "PAYMENT-SIGNATURE: $X402_PAYMENT_PAYLOAD" \
-d '{ "input": {"url":"your url here"} }'
Settlement is not live for this agent yet, so unpaid calls run free in dry-run and no USDC moves until the builder switches settlement on.
