How this service works
Deterministic decision procedure for an agent about to settle a service contract: detect subjective or ambiguous acceptance language (as agreed, satisfactory, best effort, complete) before approving final payment. Inputs: contract terms, deliverable description, quoted final payment, counterparty history. Checks: flag every subjective acceptance phrase, require an objective, verifiable acceptance test per deliverable, bind the payment trigger to a passing test rather than an invoice or elapsed
Output
A JSON object containing a plain-prose decision procedure brief (120+ words) for pre-settlement contract term vetting, including the model used, generation timestamp, generation source (llm/reasoning/deterministic), the topic, and service slug. The 'brief' and 'procedure' fields carry the actionable guidance text.
Example use cases
Agent-to-agent service contract review
“Before my agent finalizes this x402 service agreement, walk it through the pre-settlement contract term vetting procedure so I know what clauses to flag or accept.”
On-chain smart contract term audit
“I'm about to settle a smart contract on Base — can you run the pre-settlement contract vetting decision procedure and give me a plain-prose brief on what to watch out for?”
Merchant onboarding contract screening
“My autonomous merchant agent is reviewing a new supplier contract before settlement — run it through the pre-settlement contract term vetting procedure and summarize the key decision steps.”

Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-facing-pre-settlement-contract-term-vettin?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an autonomous agent needs a structured, prose-form decision procedure for vetting contract terms before any settlement action — especially in x402 or on-chain contexts where no human lawyer is in the loop. It is preferable to generic legal APIs because it is purpose-built for agent-to-agent and agent-to-merchant contract scenarios, returns a ready-to-act brief rather than raw legal text, and integrates natively with x402 micropayment flows.
Side effects
- HTTP 402 returned if payment has not been settled — agent must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Missing or malformed 'input' object returns a validation error
- Invalid method (POST, PUT, PATCH) rejected — only GET/HEAD/DELETE accepted
- If topic override is malformed or too long, the service may fall back to default topic
- Occasional LLM generation failures may result in ok:false with an error detail field
