How this service works
x402 pay-per-call APIs, MCP servers and practical AI field guides from a veteran-owned lab. Verify the provider, then pay per accepted call.
Output
A JSON object containing a count of checked items, overall status, and per-artifact results including trust state, an evidence-derived verdict, and the current registry or publisher-verified version. Also includes the price in USDC and an accepted_delivery flag.
Example use cases
Lock file freshness audit for CI pipeline
“Before I cut a release, verify all 20 packages in my lock file — mix of npm and PyPI — against live registry evidence and flag any that are stale or where my held version doesn't match the current publisher-authoritative one.”
Supply chain tamper detection
“I want to check the integrity of these 10 npm packages my mirror is caching — can you run them through CANON with the integrity hashes I have and tell me if any have been tampered with compared to what the publisher is signing?”
Publisher domain trust verification
“We're onboarding a new vendor library — can you verify that the publisher domain scriptmasterlabs.com and its Ed25519 keyset check out for the artifact 'canon-sdk' on npm, and confirm it's the current authoritative version?”
Technical details
Endpoint
POSThttps://scriptmasterlabs.com/api/canon/batch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to validate multiple packages or artifacts in a single pay-per-call request rather than making individual checks. It is especially well-suited for CI/CD pipelines, supply chain audits, or dependency lock file reviews where you need publisher-authoritative freshness data and tamper detection across npm, PyPI, API artifacts, or documentation artifacts simultaneously.
Side effects
- Invalid or unrecognized package identifier — returns an error or unknown verdict for that item
- Unsupported artifact type — rejected if 'type' cannot be inferred and is not one of npm/pypi/api/doc
- Array exceeds 100 items — request rejected with validation error
- Registry or publisher manifest unreachable — verdict may be inconclusive or stale
- Payment not accepted — x402 payment failure blocks delivery
- Integrity value format mismatch — held_integrity field not parseable against supported hash formats
