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
