# reverseEmailLookup

`POST /v1/email-to-person/single`

**Tags:** `Email lookup`

Find person by email (single)

**Endpoint:** `https://api.fiber.ai/v1/email-to-person/single`

## Description

Given an email address, find the person's LinkedIn profile and personal details.
If the person's name, company, or other identifiers are also available, use the Kitchen Sink endpoint instead — it accepts all available signals and produces better matches.
To avoid 429 errors, space requests evenly (such as 1/60th the rate limit per second) rather than bursting them all at once.

⚡ Rate limit: 3500 requests per 1 minute

💰 Cost: 2 credits per email lookup ⓘ

⏱ Recommended timeout: 1 minute ⓘ
