# Escrow Evaluator

> 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 to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability escrow-evaluator-df567477
```

Example prompt: Check whether this blog post (https://example.com/my-article) meets the job spec 'minimum 500 words, covers SEO basics, includes at least 3 subheadings' with a pass threshold of 80, and give me the signed attestation I can use for ERC-8183 escrow release.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
