AI-powered CAPTCHA solving API built for scale
Supports reCAPTCHA v2/v3 and Enterprise, Cloudflare Turnstile and Bot Challenge, AWS WAF, GeeTest, Tencent CAPTCHA, Yidun, Text CAPTCHA and more.
Integrate with official libraries for C#, Python, JavaScript, Go, and PHP, or use the API of other services via compatibility.
Chrome and Firefox extensions detect and solve CAPTCHAs automatically in the background while you browse.
Most challenge types can be solved without supplying your own proxies, simplifying setup.
Build, test, and deploy production-grade voice AI agents over API
Configure speech recognition, an LLM reasoning layer and text-to-speech through one API instead of integrating several vendors separately.
The platform handles real-time audio streaming, interruption handling and call state so conversations feel natural and responsive.
Provision Vapi phone numbers or bring Twilio, Vonage or Telnyx, and support both inbound and outbound calling from the same agent.
Simulate calls before launch, then track transcripts, effectiveness metrics and compliance signals across every production call.
