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.

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

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

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
