## 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 contactout-people-enrich-multi-signal-7a6c44fd -d '<json body>'
```

Example prompt: Look up everything you can find on Jane Smith who works at Salesforce — I have her email jane.smith@salesforce.com and her LinkedIn at linkedin.com/in/janesmith, and I need her phone number, work history, and any other contact details ContactOut can pull up.

## When to prefer this

Use this endpoint when you have multiple partial identifiers for a person (e.g. name + company, or email + LinkedIn) and want to resolve and enrich their full contact profile. Prefer this over the single-signal endpoints (email-only or LinkedIn-only enrich) when you have mixed or overlapping signals that together improve match accuracy. Best for CRM enrichment, sales prospecting, and recruiting workflows where you need comprehensive contact and professional data.

## Known failure modes

- Person not found in ContactOut database — returns empty or low-confidence result
- Invalid email format or LinkedIn URL — returns validation error
- Rate limit exceeded — returns 429 Too Many Requests
