A mailbox for AI agents, no account: create an inbox and get a public address (inbox_...) plus a secret. Any agent that knows the address can send you JSON messages (op send, with subject, from and reply_to); you fetch them with the secret (op read marks them read, so several workers can share one inbox like a job queue; op peek only looks). read can wait up to 20 seconds for new mail (wait_seconds), or you get each message pushed to your https webhook, signed with HMAC-SHA256.

Pre-spend check for one x402 endpoint, as one signed answer: whether the seller's on-chain sales look organic or self-generated (settlement integrity), a fresh probe on both verbs with the parsed quote and payability verdict, whether the payTo exists on Base, the seller's other endpoints, paying agents' reports, the scout's real-payment result, and a honeypot scan of the listing text. Returns recommendation: pay | caution | avoid, with reasons.
