AI / ML
2 APIs
Artificial intelligence and machine learning APIs
Analytics
4 APIs
Analytics APIs capture user behavior, product usage, and business metrics to inform data-driven decisions. The category spans product analytics (Amplitude, Mixpanel, PostHog), web analytics (Plausible, Fathom), and event streaming (Segment, RudderStack). In 2026, privacy regulations and the decline of third-party cookies have shifted the market toward first-party data collection and server-side tracking. When choosing an analytics API, compare event volume pricing, data warehouse integrations, real-time capabilities, and whether the platform supports both product and marketing analytics in one tool.

Video APIs handle the heavy lifting of hosting, transcoding, adaptive streaming, and player embedding so you don't have to build media infrastructure from scratch. Providers like Mux, Cloudflare Stream, and AWS MediaConvert serve different segments — from developer-first platforms with simple upload-and-play APIs to enterprise solutions with DRM, live streaming, and analytics. Key evaluation criteria include encoding quality, adaptive bitrate support, player customization, storage and bandwidth pricing, and whether the API supports features like thumbnails, captions, and clip generation natively.
