Verdicts

Lusha API + MCP

API key on every plan, including Free with 40 credits a month. At least 1 credit per request even when nothing matches.

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

Lusha API + MCP

  1. Batch up to 25 contacts a request. A single bulk request costs 1 credit, not 1 per contact
  2. Ask for phones only when needed. A phone is 5 credits against 1 for an email
  3. Use the Buying Group endpoint. Decision Makers was retired on 2026-09-04
  4. Use /v3/lookalike/contacts for contact lookalikes
  5. Back off exponentially on 429. Free keys stop at 100 requests a day

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
