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.
Give every AI agent a real inbox and one API to use it
Provision mailboxes on verified domains or a shared myagent.mx address, with clean JSON output that strips signatures and quotes.
Send over HTTP or SMTP using the same mailbox credential as a Bearer token and SMTP password, with Idempotency-Key retries and attachment support.
Bind keys to providers, delivery groups, weights, and quota windows so traffic stays inside the boundaries you set.
Signed webhooks for delivery and receipt events, an SSE stream for live mailbox clients, and typed change polling for resync.
