Top blockers
Prioritized findings for malformed 402 metadata, network or price drift, stale manifests, facilitator gaps, and discovery mismatch.
Fix the payment bug before an agent pays.
A focused human review for one public x402 endpoint or repository. Ontario turns the free evidence into a prioritized repair memo covering payment challenge, discovery metadata, security edge cases, debugging, and launch readiness.

A repair decision you can act on
Concrete remediation
Code- and configuration-level guidance for the highest-impact fix, without requesting private source, secrets, or wallet credentials.
Launch checks
Review missing tests, CI assertions, idempotency, retry behavior, and the evidence an agent should retain before payment.
Bounded recheck
One follow-up check against the same public target after the agreed repair, with a refreshed evidence summary.
Use the evidence ladder first
01 · Verify
Run the free x402 readiness verifier and save the public report ID.
02 · Scan
Run the free repository scanner or the $0.01 machine audit.
03 · Review only the gap
Request this review when the remaining blocker affects a real launch and written remediation is worth more than another scan.
04 · Scale later
Use the $199 launch pack for multi-surface catalog, MCP, README, and registry work.
Scope boundary
Useful evidence, not a safety claim
Ontario reviews observable public behavior and metadata. The review does not certify safety, guarantee settlement, promise traffic, or replace an independent security audit.
Public target only. No private repositories, production deployment, wallet custody, private keys, seed phrases, raw payment signatures, or customer data.
