Which one, for what

People Data Labs B

Good for Products and pipelines that enrich or search person and company records at volume and can write Elasticsearch or SQL queries.

Ahead on

  • Reliability, 78 against 64
  • Agent ergonomics, 77 against 72
  • Security & auth, 43 against 34
  • Payments & pricing, 35 against 10
  • Maintenance & community, 79 against 31
  • Transparency & trust, 67 against 58

Watch for

No OpenAPI file was found. The machine-readable material is a Postman collection and Elasticsearch mappings

RocketReach API D

Good for Teams that already hold a RocketReach plan and want an agent to search people and companies, reveal emails and phones, and verify single addresses over MCP.

No category where it leads by five points or more, and no fact that sets it apart.

Watch for

The pricing page is drawn by script and was not read, and the docs tell users without a paid plan to email for an API plan

Verdicts

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.

RocketReach API

The hosted MCP server has nine documented tools, OAuth 2.1 with dynamic client registration and machine-readable error codes, and searches cost no credits. Plan prices were not readable, the docs send API plan requests to email, the terms require a human account holder, and the account tool returns the account's API key to the model.

Before you call either

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

RocketReach API

  1. Search first with person_search or company_search, which cost no credits, then look up only the profile IDs needed
  2. Treat status: "pending" as normal. Poll check_person_status after at least 3 seconds, and polling is free
  3. Do not echo the account tool's output to users or logs. It includes the account's API key
  4. Send the key in the Api-Key header. The api_key query parameter is deprecated
  5. Bulk lookup takes 1 to 100 queries and needs a webhook. Results arrive at the webhook, signed in X-RocketReach-Signature
  6. Do not loop on unknown from email_verify, or on lookup_failed and not_found. The last two are terminal
