Verdicts

Dropcontact API + MCP

Pay on success, with credits refunded when no email is found. No OpenAPI spec, llms.txt or changelog.

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

Dropcontact API + MCP

  1. Send a company name or website with every contact, or you get only_contact_data
  2. Send only documented fields. New accounts get a 400 for unknown ones
  3. Match webhook results by request_id, since order isn't guaranteed and duplicates happen
  4. Poll no faster than every 30 seconds, as the not-ready response asks
  5. Post an empty contact to read the credit balance at no cost

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
