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.

Hunter API + MCP

Returns 451 for people who asked not to be processed. Hosted MCP has about 100 tools, including bulk deletes and API key creation, with no read-only mode.

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

Hunter API + MCP

  1. Treat 451 as final. The person opted out and retrying won't help
  2. Back off on 403 with a rate-limit message. 429 means the plan's credits are gone
  3. Send the key in X-API-Key, never as ?api_key=
  4. Use test-api-key to check request shapes without spending credits
  5. Use the hosted MCP at mcp.hunter.io/mcp, not the deprecated local npm package
