## Which one, for what

### Clearbit (F)

Good for: Only for teams that already hold a Clearbit contract.

Ahead on:
- Transparency & trust, 66 against 58

Watch for: No public API or MCP server an outside agent can call

### RocketReach API (D)

Good for: Teams that already hold a RocketReach plan and want an agent to search people and companies, reveal emails and phones, and verify single addresses over MCP.

Ahead on:
- Reliability, 64 against 30
- Schema & documentation, 72 against 0
- Agent ergonomics, 72 against 0
- Security & auth, 34 against 8
- Payments & pricing, 10 against 0
- Maintenance & community, 31 against 4

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: The pricing page is drawn by script and was not read, and the docs tell users without a paid plan to email for an API plan

## Verdicts

**Clearbit.** There is no public API or MCP server an outside agent can call today. Clearbit's APIs still run for existing customers behind a login, and its free tools and Logo API were retired in 2025. HubSpot's Breeze Intelligence is the route for new buyers, through HubSpot rather than Clearbit.

**RocketReach API.** 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 either

### Clearbit

1. Don't plan to call Clearbit. Hand the task to a person with an existing Clearbit account, or use HubSpot's Breeze Intelligence through HubSpot
2. Replace logo.clearbit.com links, which stopped working after 8 December 2025

### RocketReach API

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
