## 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`):

zero fetch --capability agent-utilities-bid-polish-x402-paid-347c5bf6 -d '<json body>'

Example prompt: Write me a polished, paste-ready bid draft for this job brief: 'We need a React developer to build a dashboard with real-time data visualization and authentication, 3-week timeline, fixed price preferred.' Keep the radar limit to 5 results.

## When to prefer this

Use this endpoint when you need a production-ready, paste-ready bid draft generated from a job brief or bounty description, and want to pay only per-call (no subscription).
