## 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-engineer-profile-lookup-38472156 -d '<json body>'
```

Example prompt: Pull up the DevMatch profile for GitHub user torvalds — I want to see their bio and open-source contribution ranking before deciding whether to reach out.

## When to prefer this

Use this endpoint when you need to look up a specific engineer's profile by their GitHub handle and want contribution-verified ranking data from DevMatch. Prefer this over raw GitHub API calls when you need a pre-scored, talent-marketplace view of a developer's open-source credibility. Best suited for hiring workflows, contractor vetting, or contributor evaluation where a single developer lookup is needed per call.

## Known failure modes

- Missing or invalid GitHub handle returns a validation error
- Unknown GitHub handle not indexed in DevMatch returns an empty or not-found response
- Unauthenticated call without X-API-Key or OAuth triggers an HTTP 402 payment challenge requiring USDC on Base
- Expired or insufficient USDC balance causes payment failure and no profile returned
- Rate limiting or credit exhaustion on monthly billing plans may block calls

## How this service works

Pay-per-call access to engineers ranked by verified open-source contributions and other public work. Unpaid calls to the paid resource return an x402 HTTP 402 challenge (USDC on Base). Authenticate with OAuth or an X-API-Key for monthly-credit billing instead.

## Output

Returns a JSON object containing the engineer's GitHub login name, a bio, and a profile view with data reflecting their verified open-source contributions and public work ranking on DevMatch
