## 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 coresignal-employee-multi-source-profile-by-id-0a1ffff3
```

Example prompt: Pull the full Coresignal multi-source employee profile for the person with ID 309627871 — I need their complete work history, education, skills, and any social profile links.

## When to prefer this

Use this endpoint when you already have a Coresignal numeric employee ID (e.g. from a prior search endpoint result) and need the richest possible profile data aggregated from multiple platforms. Prefer this over single-source lookups when you need comprehensive work history, education, and skills in one call. Not suitable for discovering new profiles — use search endpoints first to obtain IDs.

## Known failure modes

- Invalid or non-existent employee ID returns a 404 or empty result
- Rate limiting or payment failure returns a 402 or 429 error
- Profile may be stale if Coresignal's underlying data hasn't been refreshed recently
- Some fields may be missing or null if the person has limited public data across sources

## How this service works

## Output
