## 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-skills-api-5a47234e -d '<json body>'
```

Example prompt: Search Roster for current job listings and hiring data for 'senior Solidity smart contract developer' — I want to see who's hiring and what skills are in demand.

## When to prefer this

Use this endpoint when an agent needs pay-per-use, no-subscription access to job listing and hiring data without API key management. Best suited for on-demand skill demand lookups and job market intelligence tasks when cost predictability per call matters.

## Known failure modes

- Payment not received or insufficient USDC — endpoint returns 402 Payment Required
- Empty or malformed query string results in no matches or error
- No listings found for niche or overly specific query — success=true but empty data
- Service unavailable or upstream data source down — 5xx error
