A drop-in recognition API for image classification, drag & drop and area select challenges. One credit per solve, per-key thread limits, and real-time statistics on every request.
| Type | Solves | Success rate |
|---|
Point your existing client at this host — the endpoint is wire-compatible with the standard recognition API.
# submit a challenge curl -X POST http://HOST/v1/recognition/hcaptcha \ -H "X-API-Key: sk_your_key" \ -H "Content-Type: application/json" \ -d '{"data": {...}}'
One credit equals one solve. Failed jobs are refunded automatically, so you only ever pay for answers you actually received.
Every API key carries its own concurrency cap. Requests over the limit get a clean 429 instead of degrading everyone's latency.
Success rate, average latency and per-type breakdowns update in real time on both the customer dashboard and the admin panel.
