?>Production support — solved through the generic image API. See /supported-captchas for the live capability matrix.
Our AI-powered OCR achieves up to 99.9% accuracy on standard text and number captchas, even with distortion or noise.
We support JPG, PNG and GIF uploads (max 5MB) via the /api/process.php endpoint.
Median response is ~1.2 seconds (p95 ~2.5s, max 10s), measured on our standard distorted-text test set of 1,000 labeled images (Aug 2026). Methodology: /benchmarks.
• Low accuracy: keep text on a single line and upscale tiny images 2× — heavy rotation or overlapping characters reduce OCR accuracy.
• The response is synchronous — set your HTTP client timeout to at least 10 seconds.
• Failed requests (4xx) are not billed; only successful solves are charged.
Use this solver only on systems you own or are explicitly authorized to test (QA automation, accessibility tooling, research, load testing). You are responsible for complying with each target site's Terms of Service and applicable law. Details: Terms of Service.
