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.

ZoomInfo API + MCP

Search, lookup and similar-record calls cost no credits, and a free account with 1,000 data and 1,000 AI credits needs no card. OAuth carries 20 scopes and limits are published per package. The Licence Terms and Conditions bar disclosing benchmark results, and the two documentation sites disagree on batch sizes and rate-limit headers.

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

ZoomInfo API + MCP

  1. Call Lookup first and pass the returned IDs to Search. Unknown industry, metro or topic strings are rejected with a 422
  2. Search before Enrich. Search is free, and each newly enriched record costs one data credit
  3. Request only the scopes the task needs in the scope parameter of the token call. Omitting it grants every scope configured on the app
  4. On 429 read X-RateLimit-Rejected-Bucket and wait for Retry-After. An exhausted hourly window can mean a wait of several hundred seconds
  5. Turn off model training in the AI client before connecting the MCP server. ZoomInfo prohibits MCP data being used for training
