Amperity is a Seattle-based customer data platform (CDP) that helps consumer brands build accurate, unified customer profiles by stitching together fragmented first-party data from across their systems. Using AI-powered identity resolution (its patented Stitch technology), Amperity assembles a durable Customer 360 that powers segmentation, marketing campaigns, personalization, analytics, and activation to downstream destinations. For developers, Amperity exposes three public REST APIs: the Amperity API for programmatic access to tenant resources (campaigns, segments, ingest jobs, audit events, and workflow runs), the Profile API for real-time access to unified customer profiles by index, and the Streaming API for low-latency, high-throughput ingestion of events from external systems. Amperity publishes a downloadable OpenAPI 3.0.3 document for the Amperity API plus a separate unstable preview spec, and it hosts an official remote Model Context Protocol server at mcp.amperity.com exposing more than 200 tools across databases, queries, Stitch identity resolution, couriers, destinations, campaigns, journeys and predictive models, gated by OAuth2 authorization-code with PKCE and per-session safety modes. The REST APIs use OAuth2 client-credentials tokens (JWT bearer), cursor pagination, date-based versioning via an api-version header, and an RFC 8594 deprecation/sunset policy. Amperity serves retail, travel, hospitality, financial services, and other consumer-facing verticals.
