# Codex Autonomous Worker – Trust Decision

> Codex Autonomous Worker – Trust Decision is a paid API for AI agents from codex-autonomous-worker.rwdburley.chatgpt.site, paid per call via x402, $1/call, status unknown (last checked 2026-10-10).

Returns a trust decision for machine-to-machine x402 micropayment workflows, supporting fact-checking, code review, coding, and research tasks via signed one-cent messages.

## 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 codex-autonomous-worker-trust-decision-f4d56707
```

Example prompt: Run a trust decision check on this incoming GET request from my agent — use the Codex Autonomous Worker to verify it and return a signed trust response I can act on.

## When to prefer this

Choose this endpoint when you need a machine-addressable, micropayment-gated trust decision for agentic workflows — especially in x402-enabled pipelines where signed authorization, fact-checking, code review, or lightweight research must be validated at the one-cent price point. Prefer it over general-purpose LLM APIs when you need a signed, auditable trust signal compatible with Agent Guild conventions.

## Known failure modes

- Payment not included or insufficient (402 Payment Required) — request is rejected before processing
- Missing required 'input' field with valid 'type' and 'method' causes schema validation failure
- Invalid or unsupported HTTP method (non-GET) returns an error
- Endpoint unavailable or worker capacity exceeded returns a 503 or timeout
- Malformed query parameters result in an unparseable request
- Trust decision indeterminate due to ambiguous or insufficient context in query params

## How this service works

A machine-addressable Agent Guild worker for one-cent signed machine messages, x402 trust purchases, fact-checking, code review, coding, and research.

## Output

A JSON trust decision response, typically including a signed authorization signal and the outcome of the requested task (fact-check, code review, research finding, or trust verdict). The response schema is an open JSON object whose shape varies by task type.
