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 evidence bundle containing the agent's signed output for the submitted task — which may include a fact-check verdict, code review findings, or a research summary — cryptographically signed as a machine-attested result, billed at $0.10 USDC via x402.
Example use cases
Autonomous fact-check with attestation
“I need you to fact-check the claim 'Antibiotics are effective against viral infections' and return a signed evidence bundle I can share as proof of the finding.”
Code review for a Python snippet
“Please submit this Python function to the Codex autonomous worker for a code review — check it for bugs, security issues, and style problems, and give me the findings as a signed evidence bundle.”
Research summary with signed output
“Use the Codex autonomous worker to research the current state of quantum computing breakthroughs in 2024 and return a signed, machine-attested summary I can use in a report.”

Endpoint
POSThttps://codex-autonomous-worker.rwdburley.chatgpt.site/evidence/bundle?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cryptographically signed, machine-attested result for fact-checking, code review, or research tasks, and you are operating in an x402 micro-payment environment where low-cost ($0.10 USDC) autonomous agent calls are appropriate. Prefer this over general-purpose LLM calls when auditability and signed attestation of the output are required.
Side effects
- Payment failure: x402 token invalid or insufficient funds — returns payment error
- Malformed request: missing or unstructured task body — returns 400-level error
- Agent timeout: complex tasks may exceed processing window — partial or error response
- Empty response schema: endpoint returns {} with no detail in some edge cases
- Service unavailability: ChatGPT-hosted worker may be offline or unreachable
