# Peak Solutions

> Peak Solutions is a CAPTCHA-solving API focused on Cloudflare. It solves Cloudflare Turnstile and the Cloudflare 5-second (managed) challenge with a single POST request that returns a token in about one second. You are billed only for solves that land. Official SDKs: Python, Node, Go, Rust, C#.

Peak is a specialist, not a generalist: it solves Cloudflare Turnstile and the Cloudflare 5-second challenge, not a broad catalog of CAPTCHA types. The API is a single synchronous endpoint (POST /solve) rather than a submit-then-poll model, so integration is one call and latency is low.
