FAQ

Questions, answered plainly

Short answers about compatibility, billing and data. More detail is in the docs.

Is Solvecha compatible with NopeCHA?

Solvecha follows the request and response formats, the error codes and the endpoint paths of NopeCHA's recognition API. A client that lets you set the base URL can talk to Solvecha: replace the base URL and use your Solvecha API key. Only JSON and url-encoded form bodies are supported, not multipart.

How fast is it?

On Google's public reCAPTCHA demo (one data-center IP, 12 to 13 October 2026) our model got a token on 77.5 % of challenges (248/320, margin of error ±4.6 points) and NopeCHA on 68.2 % (225/330, ±5.0). The difference is +9.3 points, 95 % confidence interval +2.5 to +16.1. A random-answer control got 0 %. The median solver time per round was 0.46 s versus 7.95 s for NopeCHA, from an earlier run of the same demo in October 2026 (324 and 331 rounds). Solver time does not include your network. Results on other sites, IPs and captcha settings can differ.

How is usage counted?

Only successful solutions count against your daily quota. A request that could not be answered is not charged. The quota resets every day at 00:00 UTC.

What happens when my quota is used up?

New requests fail with error 16 (Out of credit) until the quota resets at 00:00 UTC. On the v1 paths this is HTTP status 403.

What are the rate limits?

Each plan has a limit for create requests per minute: Starter 60, Basic 300, Professional 600, Enterprise 1200. Requests above the limit fail with error 11 (Rate limit reached).

Which captcha types are supported?

reCAPTCHA image grids (3x3, 4x4 and 1x1), text captchas, GeeTest sliders and FunCAPTCHA (tile selection and match). See the captcha types page for the input and output of each type.

Is there a free plan?

No. You can create a free account and get an API key, but a key cannot solve anything until a plan is active. Paid plans open soon. We e-mail you when checkout is live.

What happens to the images I send?

Images are processed to produce an answer. Details are in the Privacy Policy.

Can I get a refund?

Refund terms are not published yet. They will be part of the Terms of Service before paid plans open.

Is Solvecha affiliated with NopeCHA?

No. Solvecha is an independent service. We name NopeCHA only to describe API compatibility and to compare prices.

What am I allowed to use it for?

Use Solvecha only for legitimate purposes, such as accessibility, testing your own sites, and places where you have permission. We may suspend keys that are used against the Terms of Service.
