User Agent Parser API

br0ski777/user-agent-parser-x402

Parses user agent strings to extract browser, OS, device type, and bot detection signals, served over SSE with x402 micropayment integration. The repository is sparse on implementation details, but the remote endpoint at user-agent-parser.api.klymax402.com suggests a hosted service model. You'd use this when building analytics pipelines, A/B testing systems, or bot filtering layers where you need structured data from raw user agent headers. The x402 payment layer means you're paying per parse rather than running your own UA-WHM or Browscap setup. Useful if you want to offload parsing logic and don't want to maintain regex patterns as new browsers and devices ship.
