Verdicts

Enrich Layer API + MCP

Pay-as-you-go credits from $10, non-expiring unless idle for 18 months. Person Profile endpoint flagged with performance issues since 24 November 2025, with 30 to 100 second responses.

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

Enrich Layer API + MCP

  1. Top up once before testing. Trial keys run at 2 requests a minute
  2. Set the person profile timeout to at least 100 seconds
  3. Ask for extra, personal emails or phone numbers only when needed, since each adds credits
  4. Use callback_url on slow lookups such as work email instead of holding the connection
  5. Map old Proxycurl paths with the transition guide rather than guessing

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
