## Which one, for what

### LeadMagic API + MCP (C)

Good for: Verification and email or mobile finding in automated pipelines, especially at volume on the plans with credit-free search.

Ahead on:
- Schema & documentation, 93 against 72
- Security & auth, 60 against 34
- Payments & pricing, 20 against 10
- Maintenance & community, 65 against 31
- Transparency & trust, 63 against 58

Watch for: No free tier or trial credits, plans from $99 a month

### 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 55
- Agent ergonomics, 72 against 61

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

**LeadMagic API + MCP.** RFC 9457 problem-details errors with `request_id`, and Retry-After on 429. No free tier or trial credits, plans from $99 a month.

**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

### LeadMagic API + MCP

1. Call `preview_cost` before bulk work. It's free
2. Read `X-Credits-Remaining` after each call instead of polling the balance
3. Treat 402 as out of credits and wait out Retry-After on 429
4. Keep credit-free search under 13,333 calls a day per account
5. Retry `unknown` validations later. They cost nothing

### 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
