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
A deterministic PASS or FAIL result indicating whether the ACP offering's contract is machine-checkable, accompanied by a list of specific defects found (e.g. missing JSON deliverable schema, undeclared required fields, absent input schema), each with evidence. A PASS confirms structural verifiability only, not output quality or correctness.
Example use cases
Pre-purchase ACP contract vetting
“I'm about to purchase this ACP offering — can you run the contract linter on it first to make sure it has a declared deliverable schema and proper input fields so I can actually verify what I'm getting?”
Marketplace listing quality audit
“I'm evaluating several ACP listings on the marketplace and want to filter out any that have schema defects — can you lint this offering's contract and tell me if it passes or fails the machine-checkability test?”
Developer self-check before publishing
“I just wrote an ACP offering contract — can you run the contract linter on it to catch any missing JSON output schemas or undeclared required fields before I publish it for buyers to see?”
Technical details
Endpoint
POSThttps://app.tenna.ai/api/x402/lumi/acp_offering_contract_lintWhen to prefer
Use this endpoint before purchasing or integrating any ACP offering when you need to verify that the listing is structurally machine-checkable — i.e., it declares a JSON deliverable schema, proper required fields, and an input schema. Prefer this over manual review when automating procurement pipelines or auditing multiple listings programmatically. It is a deterministic, model-free check, making it reliable and repeatable.
Side effects
- Malformed offeringContract object causes validation error
- Missing offering identifier field returns error
- Offering contract with unusual or non-standard structure may produce incomplete lint results
- Network or service unavailability returns HTTP error
