Amperity

description: '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. The APIs use OAuth2 client-credentials tokens
  (JWT bearer), 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.'
