## 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 apollo-api-apollo-people-match-enrich-by-identifier-dde33910 -d '<json body>'
```

Example prompt: Can you enrich this contact for me? I have their email — jane.doe@acme.com — and I need their job title, phone number, LinkedIn profile, and company details from Apollo's database.

## When to prefer this

Use this endpoint when you need to enrich a single person record and have at least one identifier such as email, LinkedIn URL, or name+company. Prefer this over Bulk Match when enriching one person at a time without needing webhook-based async delivery. Choose this over a company enrichment endpoint when the subject is an individual contact, not an organization.

## Known failure modes

- No match found — person not in Apollo database, returns empty or null result
- Ambiguous match — multiple people match the identifiers provided, lowest-confidence result returned
- Invalid identifier format — malformed email or LinkedIn URL causes validation error
- Insufficient identifiers — too few fields provided to uniquely identify a person
- Rate limiting or quota exceeded — HTTP 429 returned
- Authentication failure — invalid or missing API key returns HTTP 401
