Can the payment flow be understood?
Check HTTP 402 behavior, non-empty accepts entries, network and price consistency, facilitator metadata, and payment-oriented tests.
The x402 Implementation Audit is a bounded code-review-style check for a public endpoint and/or GitHub repository. It returns actionable payment, discovery, security, debugging, and launch findings: challenge gaps, network or price mismatches, missing tests, CI evidence, and credential filename hygiene.
Check HTTP 402 behavior, non-empty accepts entries, network and price consistency, facilitator metadata, and payment-oriented tests.
Check x402 manifest shape, OpenAPI evidence, MCP or registry metadata, buyer documentation, and the public route contract.
Reuse the bounded GitHub scan for implementation markers, challenge tests, CI gates, documentation, and sensitive-looking filenames. Source contents are not returned.
The paid result is designed for an agent or developer tool to act on immediately.

Start with the free readiness verifier, the free repository scanner, or the combined free catalog scorecard. Pay for this audit only when you need one fresh, task-specific implementation receipt after those checks.
Boundary: Ontario provides readiness and implementation evidence based on observable public behavior and metadata. It does not certify safety, guarantee settlement, promise agent traffic, or replace a security audit. The report never returns source contents, secret values, private keys, raw payment signatures, or wallet credentials.
If the audit finds a concrete blocker, the $49 x402 Code Review turns one public endpoint or repository into a prioritized repair memo and bounded recheck. Use the $199 Agent Catalog Launch Pack only when the remaining work spans catalog, MCP, README, and registry launch surfaces.
