## 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 fiber-ai-api-fiber-ai-twitter-handle-to-linkedin-profile-resolver-ad594aea -d '<json body>'
```

Example prompt: I have a Twitter handle @pmarca — can you find the LinkedIn profile URL that belongs to that person?

## When to prefer this

Use this endpoint when you have a Twitter/X username and need to find the corresponding LinkedIn profile for outreach, enrichment, or identity resolution. Ideal for sales and recruiting workflows where contact discovery starts on Twitter but requires LinkedIn for professional context. Prefer this over general person search when you already have the Twitter handle and want a direct, low-latency single-record lookup.

## Known failure modes

- No LinkedIn profile linked to the given Twitter handle — no result returned
