NeuroCaptcha

Errors

Every error code of the API: errorId, errorCode, what it means and what to do.

이 섹션은 영어로 표시됩니다.

Every answer is HTTP 200 with errorId. 0 means success; otherwise there are errorCode and a human-readable errorDescription:

Error
{
  "errorId": 1,
  "errorCode": "ERROR_KEY_DOES_NOT_EXIST",
  "errorDescription": "Account authorization key not found in the system."
}
  • Check errorId != 0, not the HTTP status.
  • Branch on errorCode; errorDescription is for people and may change.
  • Ids 1–55 follow the Anti-Captcha registry, ids from 90 are codes of this service. An unknown failure is ERROR_INTERNAL (90) — never errorId: 0.
  • A failed task is not charged. 2Captcha names of the codes: 2Captcha compatibility.
