## 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 devmatch-pay-per-call-engineer-hiring-1e65bd12 -d '<json body>'
```

Example prompt: Can you pull up the DevMatch profile for the engineer with login 'karpathy' — I want to see their bio and where they rank based on open-source contributions?

## When to prefer this

Choose this endpoint when you need verified, contribution-ranked engineer profiles sourced from public open-source activity, especially when pay-per-call microtransaction billing (USDC on Base) or monthly-credit API key billing is acceptable. Prefer it over generic job boards or LinkedIn-style lookups when you need programmatic, agent-friendly access to ranked developer talent with verifiable public work history.

## Known failure modes

- HTTP 402 returned for unauthenticated or unpaid calls — requires USDC payment on Base via x402 protocol or valid API key/OAuth token
- Invalid login name returns no matching profile
- Missing or expired API key results in authentication failure
- Network or upstream service unavailability may cause timeouts
- Insufficient USDC balance causes payment challenge failure

## How this service works

Pay-per-call access to engineers who uniquely fit a role, matched on open-source contributions and other public work, with evidence.

## Output

A JSON object containing the engineer's login name, bio, and a profile view field (e.g. {login_name, bio, view: 'profile'}), reflecting their verified open-source contribution rank and public work history.
