Can other agents read your agent card?
An agent introduces itself with a card published at /.well-known/agent-card.json. It is the only document another agent reads before deciding to call you. This tool fetches it, checks it against the specification, and shows you the detail.

Paid in USDC on Base via the x402 extension: send the order arguments (email, product_type, product_id, item_id — same contract as https://blinkcodes.com/openapi.json) to get a Task in state input-required carrying x402.payment.required, then send the signed payload back with the same taskId.
