Peak (Peak Solutions)

CAPTCHA-solving API for Cloudflare Turnstile and the 5-second challenge — a token in about a second, and you pay only for solves that land

Peak (Peak Solutions) is a developer-first CAPTCHA-solving API focused entirely on Cloudflare. Where most solvers spread across dozens of CAPTCHA types and make you submit a job then poll a second endpoint for the result, Peak does one thing well: it solves Cloudflare Turnstile and the Cloudflare 5-second (managed) challenge with a single synchronous POST request that returns the token in about a second. The billing model is simple and low-risk: you pay only for solves that land, and failed solves cost nothing. Pricing is pay-as-you-go, starting at $1 per 1,000 successful solves and dropping toward $0.40 at volume, with free trial credit and no credit card required to start. Peak ships official, maintained SDKs for Python, Node.js, Go, Rust, and C#, so most integrations are a few lines of code. The API returns a standard cf-turnstile-response token for Turnstile, and the cf_clearance cookie plus matching headers for the 5-second challenge. It's built for developers doing legitimate work — automation, public-data scraping, QA and end-to-end testing, and synthetic monitoring of sites you own or are authorized to test. Full documentation and an active support channel are available. Peak's focus on Cloudflare, single-call speed, and success-only pricing make it a fast, predictable choice for teams that keep hitting Turnstile.
