Escrow Evaluator is a paid API for AI agents from gogeta2-u35175.vm.elestio.app, paid per call via x402, $0.25/call, status unknown (last checked 2026-10-29).
Evaluates a deliverable (text, JSON, or URL) against a job specification and returns a pass/partial/fail verdict, score, checked criteria, and a signed EIP-712 attestation for ERC-8183 escrow compatibility.

How this service works
Evaluate a deliverable (text, JSON or URL) against a job spec (free text or JSON criteria): verdict pass/partial/fail, score, checked criteria, and a signed EIP-712 attestation whose digest is the ERC-8183 complete/reject reason. No funds held.
Output
Returns a verdict (pass, partial, or fail), a numeric score (0–100), a list of checked criteria with individual pass/fail results, and a signed EIP-712 attestation whose digest encodes the ERC-8183 complete or reject reason — enabling on-chain escrow resolution without the service holding any funds.
Example use cases
Freelance article quality gate
“I have a freelance writing job spec that requires at least 400 words, a clear introduction, and a conclusion. The writer submitted this text: 'Lorem ipsum... [full article]'. Evaluate it with a pass threshold of 75 and give me the verdict and score so I know whether to release payment.”
On-chain escrow attestation for code deliverable
“Before I trigger the ERC-8183 escrow release on Base mainnet for job ID 42 at contract 0xAbC123..., evaluate whether this GitHub README URL (https://github.com/user/repo/blob/main/README.md) meets my spec: 'must describe installation steps, include a usage example, and have a license section'. Set pass threshold to 85 and give me the signed EIP-712 attestation.”
Automated AI output grading pipeline
“I'm running an automated pipeline where an AI generates structured JSON reports. Evaluate this JSON output against the criteria {"criteria":[{"type":"min_words","value":200},{"type":"required_field","value":"summary"}]} and tell me if it passes with a score, the individual criteria results, and the attestation digest.”

Endpoint
GEThttps://gogeta2-u35175.vm.elestio.app/agents/v1/escrow/evaluate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both a human-readable quality verdict AND a cryptographic on-chain attestation (EIP-712 / ERC-8183) for escrow automation. It is uniquely suited for decentralized gig economy workflows where an agent must verify a deliverable and produce a signed reason digest for smart-contract escrow release — without any funds being held by the evaluator. Prefer it over generic LLM-based graders when you need a signed, auditable, blockchain-compatible attestation alongside the verdict.
Side effects
- Deliverable URL is not publicly accessible — returns fetch error
- Spec is ambiguous or unmeasurable — may produce unreliable criteria scoring
- Invalid chain_id or contract address format — returns validation error
- Score threshold out of range (not 1–100) — rejected by schema validation
- Malformed JSON spec or deliverable — parse error returned
- Service unavailable (upstream compute failure) — 5xx error
- Payment not fulfilled (x402 protocol) — 402 Payment Required before evaluation
