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.

People Data Labs

Monthly dated release notes, a free sandbox with synthetic data, response headers that report credits and rate limits, and a free plan of 100 records a month make the API easy to start with. No OpenAPI file was found, keys carry no scopes and may travel in the URL, and the agreement allows changes without notice.

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

People Data Labs

  1. Send the key in the X-Api-Key header. The api_key query parameter puts the secret in URLs and logs
  2. Build and test queries against https://sandbox.api.peopledatalabs.com/v5/... first. It costs no credits and allows five calls a minute
  3. Set size deliberately on search. Every record returned costs one credit, and responses over 1 MB fail
  4. Treat 404 on enrichment as no match, not an error, and 402 as credits exhausted. Neither is worth a retry
  5. On 429, wait until the x-ratelimit-reset time. Limits are fixed-window per key and per endpoint
