Nuevo soporte de API de reconocimiento de audio
¿Cuáles son los desafíos del "reconocimiento de audio"?
Los CAPTCHA de reconocimiento de audio son desafíos que generalmente requieren que el usuario escuche un clip de audio e ingrese correctamente la serie de letras o números que escuchan.
Para su conveniencia, implementamos soporte para la API de reconocimiento de audio. Si su software funciona con él y admite una configuración mínima, debería poder decodificar audios usando Death By Captcha en poco tiempo.
- Audio Recognition API: Proporcionando la cadena Base64 del archivo de audio y el idioma, la API devuelve el texto del audio que usará para enviar el formulario en la página con el desafío de audio.
Precios
Por el momento, el precio es de $0.59 por cada 1,000 desafíos de reconocimiento de audio resueltos correctamente. No se le cobrará por los audios informados como resueltos incorrectamente. Tenga en cuenta que esta tarifa se aplica solo a los nuevos desafíos de reconocimiento de audio, por lo que solo los clientes que utilicen esta API específica serán cobrados a dicha tarifa.
API de reconocimiento de audio Preguntas frecuentes:
- ¿Cuál es la URL de API de reconocimiento de audio?
-
Para usar la API de reconocimiento de audio deberá enviar una solicitud de publicación HTTP a http://api.dbcapi.me/api/captcha
- ¿Cuáles son los parámetros de publicación para la API de reconocimiento de audio?
-
- username: El nombre de usuario de su cuenta de DBC
- password: La contraseña de su cuenta de DBC
- type=13: El tipo 13 especifica que este es un API de reconocimiento de audio
- audio: Cadena codificada Base64 que representa los datos del archivo de audio. Actualmente admitimos solo el formato mp3.
- language: El lenguaje detectado del contenido de audio. Los idiomas compatibles son: en, fr, de, el, pt, ru
Ejemplo de audio de cadena codificado Base64:
