Verdicts

Prospeo API + MCP

MCP tool descriptions say when to use each tool, its credit cost and the next call. No status page, SLA or changelog.

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

Prospeo API + MCP

  1. Call search_suggestions before using location, technology or industry filters, or the search returns nothing
  2. Pass person_id values from search into bulk_enrich_person, 25 at a time
  3. Branch on the body error_code, not the HTTP status, which is 400 for most failures
  4. Set enrich_mobile only when needed. A mobile costs 10 credits against 1 for an email
  5. Use Enrich Person. The old Email Finder endpoint was removed in March 2026

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
