Seamless.AI is a B2B sales intelligence platform that provides real-time contact and company data to help sales teams find and connect with their ideal customers. The platform uses artificial intelligence to continuously verify and update contact information including emails, direct dials and mobile numbers. Its Public API v1 is a three-hop enrichment pipeline — search, research, then collect by polling or webhook — secured with an API key in a Token header or OAuth 2.0, and metered in research credits rather than API calls. Alongside the nine-operation REST API, Seamless.AI operates a hosted Model Context Protocol server exposing 54 tools across search, research, lists, saved searches, campaigns, templates, email, calls, tasks and activity, secured with OAuth 2.1, dynamic client registration and published per-tool risk tiers.
