Agent Delivery Dedupe Key API for agents
Agent Delivery Dedupe Key: Agent Delivery Dedupe Key derives a stable non-secret key from operation and caller item identity from bounded caller-supplied values without an external provider. Call Agent Delivery Dedupe Key before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for Agent Delivery Dedupe Key as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.

One command, attributed.
The source header follows this discovery route through challenge, payment and delivery without exposing the buyer or request body.
