MCP/x402 endpoint audit

Turn crawler attention into a buyer-safe paid endpoint path.

If agents, directories, or developer tools can find your MCP or x402 endpoint but nobody buys, the problem may be trust evidence: price metadata, payment challenge, manifest quality, MCP discovery, and proof that a wallet can safely decide before spending.

Who this is for

Paid API owners

You expose an endpoint agents could pay for, but the payment story is unclear or unproven.

MCP tool builders

You want agent hubs and directories to understand what your tool sells and how payment works.

x402 marketplace candidates

You need public evidence before a listing, submission, or buyer handoff makes sense.

Teams with attention but no conversion

You have crawler hits, clicks, or stars, but no qualified buyer request or paid call yet.

Audit scope

Run the local proof path first

Ontario keeps the first step free and evidence-based. Check whether a machine can understand the endpoint before asking any wallet to sign.

Revenue truth boundary

This page is an owned public distribution surface. It can create crawler and click evidence, but it is not customer revenue. Ontario should count revenue only after a real mini-check request, buyer reply, signup, paid call, or payment is recorded. The audit is not a guarantee of future revenue, safety, legal compliance, listing acceptance, or marketplace approval.

Reference proof

Ontario's own live rail proof is the benchmark example. It proves the rail can settle; it does not prove external buyer demand.
