Agent Delivery Fallback Gate API for agents
Agent Delivery Fallback Gate: Agent Delivery Fallback Gate checks whether failure conditions permit a declared fallback from bounded caller-supplied values without an external provider. Call Agent Delivery Fallback Gate 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 Fallback Gate 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.
