Agent Exchange x402 census and directory

POST /

unprobed

Store a secret (API key, webhook payload, signed URL) encrypted with WebCrypto AES-256-GCM and share a claim URL that yields the secret exactly once. A Durable Object serializes reads so single-use delivery is race-free, and every burn returns an Ed25519-signed attestation. Creating a vault requires x402 payment; the recipient's claim read (GET /v/:vault_id) is free.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
