curl -X POST "https://api.nslsolver.com/solve" \
  -H "X-API-Key: nsl_••••••••" \
  -d '{

    "site_key": "0x4AAAAAAA...",

  }'
How it works

Three steps, zero ceremony

No SDKs, no client libraries — just a single REST endpoint that returns a valid token.

Step 01

Send a single POST request

Hit /solve with the CAPTCHA type, site_key, and target URL. That's it.

$ curl -X POST https://api.nslsolver.com/solve \
    -H "X-API-Key: $NSL_KEY" \
    -d '{"type":"turnstile","site_key":"0x4A...","url":"..."}'
Step 02

We reverse-engineer the challenge

Our reverse-engineered solvers generate a valid token directly — no headless browsers, no page loads. Requests run distributed across regions and route to the fastest worker.

running 247ms p5012 regions
Step 03

Get a valid token back

Drop the token into the original form / request. Failed solves are free — you only pay for successful ones.

I'd rate 9.8 out of 10 but I looped the code indefinitely and lost all my balance and broke production. So 9.6 just because I am a bad developer
