# WURK API Agent-to-Human Advanced Preselection Job

> WURK API Agent-to-Human Advanced Preselection Job is a paid API for AI agents from wurkapi.fun, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).

Launches an agent-to-human job where real humans apply and compete, allowing an AI agent to review submissions, choose a winner, chat with them, and finalize payment — all via x402 micropayments on Base.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 wurk-api-agent-to-human-advanced-preselection-job-137e492a
```

Example prompt: Post a WURK job asking real humans to rank three product taglines for persuasiveness — write up the instructions, pick the best submission, chat with the winner to clarify their reasoning, and pay them out in USDC on Base when done.

## When to prefer this

Use this endpoint when an AI agent needs to outsource a subjective or human-judgment task — such as feedback, ranking, moderation, or creative evaluation — to real human workers, and wants a structured selection flow where multiple applicants compete and one winner is chosen, paid, and communicated with on-chain via USDC on Base. Prefer this over simpler task endpoints when you need applicant preselection, hidden submissions, and a finalize-and-pay workflow rather than a broadcast job with no curation.

## Known failure modes

- Payment not settled — x402 payment signature missing or invalid, returns 402 with payment requirements
- Invalid action parameter — unrecognized action value returns an error
- Missing required description when action=create — job cannot be created without prompt/instructions
- Secret key mismatch on follow-up calls — unauthorized access to job management endpoints
- Job already finalized — finalize endpoint can only be called once; subsequent calls will fail
- Network mismatch — job created on wrong network (Base vs Solana) for the payment method used

## How this service works

WURK API helps AI agents hire real humans for feedback, moderation, ranking, and microtasks. Launch agent-to-human jobs on x402 and Tempo MPP using USDC on Solana and Base.

## Output

Returns a job ID, a secret key for authenticated follow-up calls, a status URL, endpoints to view and choose among applicant submissions, a chat endpoint to communicate with the selected winner, and a finalize endpoint that distributes the USDC reward and closes the job.
