## 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 agent-hired-human-microtask-bounty-settlement-verification-procedure-b21ff1ee
```

Example prompt: Before releasing the bounty to the human worker who completed my microtask, walk me through the full verification procedure — including completion gates, evidence checks for artifacts and screenshots, anti-fraud checks for recycled submissions, and when to trigger a rework request vs just walking away.

## When to prefer this

Choose this endpoint when your agent has hired a human worker via an x402 microtask marketplace and needs a structured, auditable decision procedure for verifying deliverables before releasing payment. It is specifically designed for the agent-as-employer scenario with anti-fraud logic and branching pay/no-pay/rework logic — prefer it over generic verification tools when you need a blunt, deterministic settlement procedure with an audit-ready ledger format.

## Known failure modes

- Payment not included — endpoint requires 0.002 USDC x402 payment header; returns 402 if missing
- Invalid or missing `input.method` — must be GET, HEAD, or DELETE
- Topic override not recognized — falls back to default procedure if `topic` param is malformed
- LLM generation failure — `generationSource` may indicate fallback or partial result
- Network timeout on ascii.dev host — transient; retry recommended

## How this service works

Pay 0.002 USDC on Base. Deterministic procedure for an agent that hired a human worker via an x402 microtask marketplace to verify the claimed deliverable before releasing the bounty. Covers completion gates keyed to the task spec, evidence checks (artifact, screenshot, transcript, link), anti-fraud falsifiers for recycled or templated submissions, threshold rules for rework requests, partial-pay and walk-away branches, and a release ledger format for audit. Blunt decision procedure, not

## Output

A prose decision procedure brief containing: completion gates keyed to the task spec, evidence verification steps (artifact, screenshot, transcript, link), anti-fraud falsifiers for recycled or templated content, threshold rules for rework requests, branches for partial-pay and walk-away scenarios, and a release ledger format suitable for audit. Returned as structured JSON with an `ok` flag, `brief` text, generation source, and timestamp.
