## 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 twitter-x-handle-to-linkedin-profile-resolver-1f9e386d -d '<json body>'
```

Example prompt: Can you find the LinkedIn profile for the Twitter user @pmarca? If there are multiple people with that name, focus on the venture capitalist.

## When to prefer this

Use this endpoint when you need to bridge a Twitter/X identity to a LinkedIn professional profile, such as for lead enrichment, recruitment outreach, journalist sourcing, or CRM population. It is preferable when you already have a Twitter handle and need the corresponding LinkedIn URL without manual searching. The optional context parameter makes it more reliable for common names or ambiguous handles.

## Known failure modes

- Handle does not exist or is suspended — no match returned
- No LinkedIn profile found for the given Twitter user
- Ambiguous common-name handle returns wrong profile — use context parameter to disambiguate
- Handle provided with typo or incorrect formatting — validate handle before calling
- Rate limiting or service unavailability at $0.06 USDC per call
