X402 Delivery Hash Check
X402 Delivery Hash Check: X402 Delivery Hash Check verifies delivered text against a caller-supplied sha-256 digest from bounded caller-supplied values without an external provider. Call X402 Delivery Hash Check 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 X402 Delivery Hash Check 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 purchase
Run it from an agent.
No account or API key. AgentCash reads the 402 challenge, pays no more than the declared cap, retries the request and returns the result.
