Developer documentation

Your workspace API.

Authentication, balances and the current availability of Quick Solver API.

hCaptcha solving is live: POST /api/v1/solve returns a token from a real browser session, verified with siteverify before it leaves the engine. Failed attempts are not charged.

Overview

Base URL: https://quicksolverapi.com. All requests use HTTPS. Account balances belong to the API key used for authentication.

Authentication

Send your API key in the x-api-key header. Obtain your Regular or VIP key from your dashboard. Regenerating a key invalidates its previous value and preserves its remaining balance.

x-api-key: YOUR_API_KEY

Quick start

Create your account.
Open API Keys and copy your Regular or VIP key.

Solve

POST /api/v1/solve

Submits one hCaptcha challenge. The engine solves it in a real Chrome session and the token is verified with siteverify before it is returned. One solve is charged to the key only when a token is returned.

{"sitekey":"5dec8bf6-1326-4a56-b8a4-d724f7a681f0","url":"https://example.com/login","proxy":"user:pass@host:port"}

{
  "success": true,
  "token": "P1_...",
  "verified": true,
  "tier": "regular",
  "ms": 6400,
  "remaining_solves": 99
}

Optional proxy routes the session through your own IP, url is the target page, rqdata is forwarded for enterprise sitekeys.

Errors: 401 bad key, 402 no balance, 429 over 60 solves/minute, 502 no token this attempt (not charged).

Balance

GET /api/account/balance

Returns the authenticated key’s remaining allowance, display prefix, tier and account mode. A missing, revoked or invalid key returns HTTP 401.

{
  "success": true,
  "remaining_solves": 100,
  "api_key_prefix": "qs_live_…",
  "tier": "regular"
}

Thread availability

No processing worker pool is connected. The dashboard’s thread limits describe account configuration; active thread usage remains zero while processing is unavailable.

console.log(await response.json());

Go example

package main

import (

func main() {
    req, err := http.NewRequest("GET", "https://quicksolverapi.com/api/account/balance", nil)
    if err != nil { panic(err) }
    req.Header.Set("x-api-key", "YOUR_API_KEY")
    client := &http.Client{Timeout: 20 * time.Second}
    response, err := client.Do(req)
    if err != nil { panic(err) }
    defer response.Body.Close()
    body, err := io.ReadAll(response.Body)
    if err != nil { panic(err) }
    fmt.Println(response.StatusCode, string(body))
}

USDT ERC20 payments

Create a payment quote in Billing, use the receiving address displayed there, and submit your Ethereum transaction hash. Support checks the deposit and credits the selected Regular or VIP key. A submitted hash alone does not credit your account.
