TAM Graph Review 2026: 408 Million Contacts for $199 a Month With No Credits

A standalone review of TAM Graph, following our ranking of ten B2B lead databases for use by AI agents. It covers the data, the access routes, the two published plans, the written limits and the features we did not see elsewhere. TAM Graph pages and API docs were read on 2 September 2026 and the pricing page was rechecked on 23 September.

  • Data: 60M+ company records and 408M+ people records with work emails and mobile numbers
  • Access: website search, CSV, REST API and an MCP server on the same subscription
  • Plans: free trial with 50 requests (card taken, not charged); Pro at $199 a month, no credits or seats
  • Fair use: 5 requests per second, 500,000 records per day, 20-second query timeout
  • Distinct features: plain-English find endpoint, 10,000-match lookalike search, per-row email status
  • Drawbacks: find results can take up to a day; guessed addresses need filtering
