Find a person's email or phone

Find a person's email or phone

Starts a lookup that finds a person's verified email, phone number or LinkedIn profile, or verifies an email you have, and returns an id to fetch the result with.

Note: Runs asynchronously: fetch the result with GET /enrich/{enrichId} or pass a webhookUrl. Each enrichment spends credits, so confirm before running it on many people.

Set up

Use the first option your agent supports.

CLI (official)

Install the command and sign in with it, then confirm it runs.

npm install -g @lemlist-official/cli
lemlist --version

Run lemlist api POST /enrich.

API (official)

• Base URL: https://api.lemlist.com/api
• Endpoint: POST /enrich
• Auth: send the header Authorization: Basic $LEMLIST_API_KEY
• Get a key: https://app.lemlist.com/settings/integrations
• Docs: https://developer.lemlist.com/api-reference/getting-started/authentication

Note: LEMLIST_API_KEY holds the base64 of :<api key>, an empty username and the key; 20 requests every 2 seconds per key.

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

Rules

• Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
• Never print API keys.
