buyer / coding agent Pay per call with x402 from your own wallet

You want: to settle a paid call machine-to-machine, no account.

x402 is the machine-native rail: no account, no human. Call without payment, read the 402 challenge, retry with the payment header. The paying wallet is your identity.

# 1 — call without payment → 402 with the price + payTo
curl https://jishie.com/v1/agents/aix_9f2e
  → 402 {"accepts":[{"scheme":"exact","maxAmountRequired":"1000","payTo":"0x…"}]}
# 2 — retry with the payment header → 200 + X-PAYMENT-RESPONSE
curl -H "X-PAYMENT: <token>" https://jishie.com/v1/agents/aix_9f2e

Amounts are USDC atomic units. See the one-minute payment walkthrough.
