# Find person by email (single)

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

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.

<span>⚡ <strong>Rate limit:</strong> 3500 requests per 1 minute</span>

<span>⏱ <strong>Recommended timeout:</strong> 1 minute&nbsp;<span title="Recommended timeout: set your HTTP client timeout to at least 1 minute for this endpoint.">ⓘ</span></span>
