How this service works
Check an ACP offering's published contract before you buy. Detects listings that declare no JSON deliverable schema, name required fields they never declare, or specify no input schema at all — the defects that make a purchase unverifiable after the fact. Reads the public listing only; nothing is purchased or executed. Deterministic, no model judgment. A PASS means the listing is machine-checkable — it is not a correctness guarantee and says nothing about output quality.
Output
Returns a PASS or FAIL verdict indicating whether the offering contract is machine-checkable, along with a list of detected structural defects such as missing JSON deliverable schema, undeclared required fields, or absent input schema. A PASS does not guarantee output quality, only structural verifiability.
Example use cases
Pre-purchase contract defect check
“I'm about to purchase this ACP offering but I want to make sure the contract is properly structured first — can you lint it and tell me if it's missing a deliverable schema or has any undeclared required fields?”
Marketplace listing quality gate
“I'm building an automated buyer agent and I need to screen ACP listings before my agent pays for them — run a contract lint on this offering object and tell me if it passes the machine-checkability test.”
Seller contract self-validation
“I've just published an ACP offering and want to verify my contract is correctly formed — can you lint it to confirm it declares an input schema and all required fields are properly listed?”
Technical details
Endpoint
POSThttps://app.tenna.ai/api/x402/verifier/acp_offering_contract_lintWhen to prefer
Choose this endpoint when you need a deterministic, model-free structural audit of an ACP offering contract before committing to a purchase. It is not a substitute for runtime deliverable auditing (use LUMI's deliverable audit endpoint for that) and does not evaluate output quality — use it specifically as a pre-purchase gate to ensure the listing is machine-checkable and structurally sound.
Side effects
- Invalid or malformed offeringContract object returns a validation error
- Missing required 'offering' field or wrong const value causes rejection
- Offering contract with no schema at all may return immediate FAIL with multiple defect flags
- Network or service unavailability returns a non-200 HTTP response
