## 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 roster-career-search-api-c042a420 -d '<json body>'
```

Example prompt: Search Roster for software engineer job listings — I have 4 years of experience, strong skills in Python and AWS, and my goal is to land a backend role at a growth-stage startup.

## When to prefer this

Choose this endpoint when an AI agent needs on-demand job listing data without requiring API key registration or subscriptions — ideal for pay-as-you-go agent workflows that need hiring data programmatically, especially when the agent can handle USDC micropayments via x402.

## Known failure modes

- Missing required 'role' field returns a validation error
- Overly niche or unrecognized role strings may return empty results
- Payment failure in USDC/x402 results in request rejection before data is returned
- Network timeout on the Vercel serverless function may occur under load
