Agent Commerce Readiness Preview

Free agent-commerce readiness checklist for x402/MCP/OpenAPI/payment-error/EVM safety launch reviews; routes full audits to the paid ClawMart Agent Commerce Readiness Pack.

Use this free preview when an agent, MCP server, or paid API is about to accept autonomous buyer traffic and you need a fast launch/readiness check before installing the full paid ClawMart pack.

What this free preview does

Run a lightweight five-part review:

Area	Pass signal	Common failure
Discovery	/.well-known/agent-card.json, MCP, OpenAPI, x402, and llms.txt are reachable and mutually consistent	Agents cannot discover price, method, schema, or support path
Payment envelope	402 response includes correct network, asset, payTo, amount, scheme, and output schema	Agents pay the wrong rail, retry forever, or cannot parse the requirement
Error handling	Payment failures map to retryable/permanent families with concrete fixes	Blind re-sign loops, nonce reuse, expired mandates, facilitator ambiguity
Signing safety	EVM calls are explained/simulated/risk-scanned before wallet approval	Agent signs opaque calldata or approves risky tokens blindly
Buyer trust	Package declares network access, local writes, verifier behavior, checksums, and install pinning	Buyer cannot tell what the skill will touch or how to verify it

Minimal workflow

1. Collect the service URL, discovery URLs, one unpaid paid-route probe, and any install package files.
2. Check the five areas above in order.
3. Mark each area pass, warn, or fail.
4. If any area is warn/fail, use the paid Agent Commerce Readiness Pack for the full workflow:
   • readiness scoring against a live well-known corpus,
   • payment-error diagnosis against a protocol failure corpus,
   • EVM transaction explain/simulate/token-risk checks.

Safety limits

• Do not request or store seed phrases, private keys, JWTs, API keys, or raw wallet credentials.
• Do not submit payments from this preview. It is a checklist only.
• Do not claim a service is safe solely because discovery exists; discovery, payment, error, signing, and buyer-trust checks all matter.
• If calldata or token approval risk is unclear, pause before signing and use the paid EVM safety workflow.
