Score, ordered fix plan and a ready-to-publish server.json. $0.25 per call. Not charged for errors or "need more detail" answers.
• POST/recalls$0.02Is this product or vehicle recalled? US government recall notices: CPSC consumer products by brand + model or UPC, NHTSA vehicles by year/make/model.

• POST/paycheck$0.1Will an agent's payment to your x402 endpoint go through? One unpaid call: checks the 402 and payment request (v1/v2), the token's EIP-712 domain against the contract on-chain (the usual cause of invalid-signature payments), network, amount, payTo, timeout, CORS for browser agents, resource URL and Bazaar discovery, with exact fixes. Never pays. $0.10 per call. Not charged for errors or "need more detail" answers.

• POST/packet$1.5Dispute evidence for an AI-agent purchase: given a Tethered Trust receipt_id, one printable page and JSON with the suitability decision made before buying, the products checked, sources with dates, the linked order / AP2 mandate / ACP or UCP checkout, records and recall notices that changed since, reported outcomes and Ed25519 signature verification. $1.50 per call. Not charged for errors or "need more detail" answers.
• POST/verify$0.1Independent check that a public web page actually works before an agent reports it done: it loads, given text is visible (desktop or mobile), a link or button leads to the expected address, no script errors, no broken same-site links. Pass / fail / couldn't-verify per check, a screenshot and a signed receipt. Read-only. $0.10 per call. Not charged for errors or "need more detail" answers.
• POST/lwatch$3Keep an MCP server findable: a daily launch check for 30 days (health, official MCP Registry version, Glama, x402 Bazaar, npm, PyPI, discovery files) with a signed webhook when anything changes. $3 per 30 days, renew with watch_id. $3.00 per call. Not charged for errors or "need more detail" answers.
• POST/verify_mcp$0.1Is this MCP server actually working? We connect as an MCP client (initialize + tools/list), check every tool has a usable inputSchema and description, that named tools exist, and optionally run one sample call on a read-only tool. Pass / fail / couldn't-verify per check with a signed receipt. We never sign in or call tools that change things. $0.10 per call. Not charged for errors or "need more detail" answers.
• POST/checkout$0.25Check a UCP / ACP agent checkout (or plain line items) right before paying: safe_to_checkout, what to resolve first (adapters, questions), per-line decisions and a signed receipt. $0.25 per call. Not charged for errors or "need more detail" answers.
