## 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 people-data-labs-person-identify-0786f7da
```

Example prompt: Can you identify who 'Jane Thornton' is — she works at Accenture and I think she's based in Chicago? Return all possible matches with confidence scores.

## When to prefer this

Use this endpoint when you have partial or ambiguous information about a person and want multiple candidate matches ranked by confidence, rather than a single definitive result. Prefer this over exact-match lookups when the input data may be incomplete, misspelled, or uncertain. Ideal for prospecting, contact enrichment, and identity resolution workflows where you need to evaluate several possible matches before committing to one.

## Known failure modes

- Insufficient identifying information provided — returns empty or low-confidence matches
- Person not found in People Data Labs database — returns zero matches
- Invalid LinkedIn URL or profile format — query parameter rejected
- Rate limit or quota exceeded — HTTP 429 error
- Payment failure — HTTP 402 if USDC payment not processed
- Ambiguous inputs returning many low-confidence candidates requiring manual disambiguation

## 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 records ranked by confidence score, each potentially containing name, email addresses, phone numbers, LinkedIn profile, current and past companies, location, job title, and other professional details sourced from People Data Labs.
