Verdicts

Crustdata API + MCP

Per-field credit prices, readable per account from /account/endpoints, and X-Credits-Used on every response. No status page and no SLA.

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

Crustdata API + MCP

  1. Always send x-api-version: 2025-11-01. Unpinned calls get the latest version
  2. Call /account/endpoints first to see what your plan enables and what each field costs
  3. Ask only for the premium field groups you need, since each one bills
  4. Poll GET /batch/{id} before submitting more batch jobs. Active jobs count against a cap of 5 to 30
  5. Read the crustdata://catalog resource before calling MCP tools

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
