## How to call it through Zero

```

Example prompt: I have partial info on a lead — her name is Sarah Chen, she works at Stripe in San Francisco. Can you look her up in People Data Labs and return up to 20 possible matching profiles with confidence scores so I can identify the right person?

## When to prefer this

Use this endpoint when you have incomplete or partial person data (e.g. just a name and employer, or a name and city) and need to discover candidate matches with confidence scores before committing to a full enrichment. Prefer this over the Person Enrich endpoint when you are not confident you have a unique identifier and want to see multiple possible matches ranked by likelihood rather than a single resolved profile.

## Known failure modes

- Insufficient input data to return any candidates — requires at least one meaningful identifier
- No matches found for the provided partial information — returns empty candidate list
- Rate limit exceeded — HTTP 429
- Invalid or missing API key — HTTP 401
- Ambiguous query returning low-confidence results — all candidates below useful threshold

## How this service works

Broad person lookup returning up to 20 candidate matches with confidence scores. Useful when you have partial info and want multiple possible matches.

## Output

Returns up to 20 candidate person profiles ranked by confidence score, each containing available identifying information such as name, email, phone, LinkedIn URL, job title, company, and location — allowing the caller to select the most likely match from partial input data.
