What is ilovecaptcha?

ilovecaptcha is a REST API that solves CAPTCHA challenges automatically. A client sends the challenge parameters over HTTPS, the solving engine processes them, and the API returns the token or text the target site expects. It is aimed at developers who hit CAPTCHA walls inside automated test suites, monitoring jobs and data-collection pipelines.

Why is automated CAPTCHA solving needed?

Because a CAPTCHA stops an unattended pipeline dead, and because solving one costs real time. Cloudflare measured an average of 32 seconds per challenge and, extrapolating to 4.6 billion internet users seeing roughly one CAPTCHA every ten days, estimated the global cost at about 500 human years per day.

How does the solving API work?

In three steps, over a single HTTPS connection. You submit the challenge or its site parameters to the API, the engine solves it asynchronously in the background, and your client retrieves the resulting token or text and injects it into the request that was blocked. The submit and retrieve steps are separate so that a slow challenge never holds an HTTP connection open on your side. Submit the challenge.

How do I integrate the API into my stack?

With plain HTTPS requests and JSON payloads, authenticated by an API key. Any language able to make an HTTP call can drive it, with no SDK to install and no proprietary transport to learn.

What counts as acceptable use?

Work you are authorised to perform. The API is built for testing and monitoring your own applications, QA and accessibility automation, availability checks, academic research, and collecting publicly available data in line with the target site's terms and applicable law. Credential stuffing, spam, payment fraud and any activity a target site's terms prohibit are outside the intended scope and will not be supported.
