Verdicts

FullEnrich API + MCP

Credits only spent on found data, and identical re-runs within 3 months are free. Enrichment sources are third-party providers the vendor doesn't name.

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

FullEnrich API + MCP

  1. Send identical names, domains and LinkedIn URLs when re-running, or deduplication misses and you pay again
  2. Expect 30 to 90 seconds a contact. Use the webhook or poll get_enrichment_results
  3. Ask for mobiles only when needed. They cost 10 credits against 1 for a work email
  4. Call list_industries and list_seniorities before filtering search
  5. Use the 0-credit test contacts in the docs to check an integration

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
