# RocketReach API (slim)

> RocketReach is a contact and company database with people and company search, contact lookup, bulk lookup and single-address email verification. Agents reach it through a REST API (v2) with an account API key, or a hosted MCP server with OAuth.

Assessment: The hosted MCP server has nine documented tools, OAuth 2.1 with dynamic client registration and machine-readable error codes, and searches cost no credits. Plan prices were not readable, the docs send API plan requests to email, the terms require a human account holder, and the `account` tool returns the account's API key to the model.

## Before you call it

1. Search first with `person_search` or `company_search`, which cost no credits, then look up only the profile IDs needed
2. Treat `status: "pending"` as normal. Poll `check_person_status` after at least 3 seconds, and polling is free
3. Do not echo the `account` tool's output to users or logs. It includes the account's API key
4. Send the key in the `Api-Key` header. The `api_key` query parameter is deprecated
5. Bulk lookup takes 1 to 100 queries and needs a webhook. Results arrive at the webhook, signed in `X-RocketReach-Signature`
6. Do not loop on `unknown` from `email_verify`, or on `lookup_failed` and `not_found`. The last two are terminal
