## 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 orthogonal-fiber-contact-reveal-single-42402d55 -d '<json body>'
```

Example prompt: Can you find the email address and phone number for this person on LinkedIn: https://www.linkedin.com/in/william-h-gates — and please validate the email before returning it?

## When to prefer this

Choose this endpoint when you need fast, single-record contact enrichment from a LinkedIn URL and want both emails and phone numbers in one call. It is the best balance of speed, cost ($0.14 per call), and coverage for individual lookups. Prefer the batch endpoint when processing many records at once to optimize throughput, and prefer this single endpoint when you need results synchronously and immediately.

## Known failure modes

- LinkedIn URL not found or invalid slug — returns empty or error response
- Person has no findable contact data in the database — returns empty contact arrays
- Rate limiting or quota exceeded — returns 429 or payment error
- Invalid LinkedIn URL format — returns validation error
- Email validation service timeout — emails returned without validation status

## How this service works

Standard synchronous contact reveal. Returns emails and/or phone numbers for a person given their LinkedIn URL. Best balance of speed, cost, and coverage.

## Output

Returns an object containing one or more email addresses and/or phone numbers associated with the person at the given LinkedIn URL. If email validation was requested, each email includes a bounce-validation status indicating deliverability.
