## How to call it through Zero

```sh
zero fetch --capability fastaf-linkedin-profile-lookup-cb956f0c
```

Example prompt: Can you pull the public LinkedIn profile for williamhgates — I need their full name, headline, location, and work history as structured data?

## When to prefer this

Choose this endpoint when you need structured JSON from a public LinkedIn person profile and want guaranteed no-charge on failures. Prefer it over generic web scrapers when you need reliably parsed fields like experience and education, and over LinkedIn's official API when you need quick pay-per-use access without OAuth setup.

## Known failure modes

- Invalid or non-existent profile slug returns an error rather than settling payment
- Private profiles with no public data may return empty or minimal fields
- Rate limiting or LinkedIn blocking may cause retrieval failure with no charge
- Malformed slug (e.g. full URL instead of slug) causes a validation error

## How this service works

LinkedIn public profile API for AI agents: retrieve a person by profile ID or slug for lead research and profile enrichment. Returns a JSON array with name, headline, location, public identifier and biography when available; public data only. Provided by FastAF LinkedIn Public Profiles. Price: $0.060000 USDC per successful call.

## Output

A JSON array containing the person's public LinkedIn data including fullName, headline, location, about summary, public_identifier, and arrays for experience and education entries — only data visible without login is returned.
