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 verdict indicating whether the offering contract is machine-checkable, accompanied by a list of specific structural defects found — such as missing JSON deliverable schema, required fields that are referenced but never declared, or a completely absent input schema. A PASS confirms the listing is structurally verifiable but does not guarantee output quality or correctness.
Example use cases
Pre-purchase offering contract check
“I'm about to buy an ACP offering but want to make sure the contract is actually machine-checkable first — can you run the LUMI contract linter on this offering object and tell me if it passes or what defects it finds?”
Marketplace due diligence for agent builder
“I'm building an agent that auto-purchases ACP services and I need to filter out listings with broken contracts — lint this offering contract with LUMI and flag it if it's missing a deliverable schema or has undeclared required fields.”
Audit offering before integration
“We're integrating an ACP offering into our pipeline and want to validate the contract structure before wiring it up — can you use LUMI to check that its input schema and deliverable schema are properly declared and there are no missing field definitions?”
Technical details
Endpoint
POSThttps://app.tenna.ai/api/x402/lumi/lumi_acp_offering_contract_lintWhen to prefer
Use this endpoint when you need a fast, deterministic, zero-purchase structural check of an ACP offering contract — specifically to catch listings that lack JSON deliverable schemas, reference undeclared required fields, or have no input schema at all. Prefer this over manual inspection or model-based judgment when you want a binary machine-checkable verdict before committing to a purchase. Ideal for automated pre-purchase pipelines or marketplace quality filters.
Side effects
- Invalid or unrecognized offering identifier returns an error
- Malformed offeringContract object (not valid JSON/object) causes a parse error
- Missing required 'offering' field results in a validation error
- Offering contract with no schema properties at all may return ambiguous results
- Network or payment failure for the $0.01 USDC x402 transaction blocks the call
