Preguntas frecuentes sobre precios
¿Qué son los conjuntos de datos personalizados?
Puedes solicitar un conjunto de datos personalizado y adaptado a tus necesidades, entregado a petición o programado. Adecuado para empresas con requisitos y dominios específicos que no están en el mercado de conjuntos de datos de Bright Data.
¿Qué son los conjuntos de datos del mercado de Bright Data?
Extractores listos para usar de los sitios web más populares, creados, mantenidos y validados por Bright Data. Los datos históricos y recientes están disponibles para su compra inmediata. Los conjuntos de datos se pueden personalizar para adaptarse a cualquier requisito empresarial, lo que reduce los costes y permite la adquisición precisa de datos.
¿Cómo funciona la API de Dataset?
Los 3 puntos finales principales de la API tienen distintos propósitos en el flujo de trabajo de recopilación de datos, lo que facilita un proceso estructurado y eficiente para obtener conjuntos de datos personalizados.
- Solicitar una recopilación: el paso inicial es definir los datos que deseas recopilar. Esto se usa para especificar los parámetros de una nueva colección de conjuntos de datos, por ejemplo, para definir el ID y el tipo del conjunto de datos, o para descubrir nuevos datos o especificar colecciones de URL.
- Comprobar el estado de la recopilación: este paso implica consultar la información de una solicitud de recopilación de datos existente para conocer su estado actual. Se utiliza para comprobar el estado o los detalles de una solicitud de recogida, como el número total de líneas, la frescura de los datos u otros datos pertinentes.
- Iniciar una recopilación: este paso desencadena la recopilación de datos y pasa de la fase de solicitud a la fase de recopilación de datos real. Se usa después de definir los parámetros de recopilación y cuando está listo para iniciar el proceso de recopilación de datos.
La diferencia entre una compra única y una suscripción
Las compras únicas se calculan de acuerdo con el coste mínimo por registro con los descuentos aplicables. El modelo de precios de suscripción es el mismo, pero los descuentos son más ventajosos debido al compromiso con las compras continuas.
¿Con qué frecuencia actualizas tus conjuntos de datos?
- La frecuencia de actualización de nuestros conjuntos de datos personalizados depende de los requisitos del cliente, que pueden especificarse a través de nuestra API, plataforma o configuración de suscripción.
- Para nuestros conjuntos de datos de mercado, la cadencia de actualización varía. Una parte de los datos se actualiza diariamente a través de nuestra red, mientras que el resto se actualiza según un cronograma determinado por nuestro equipo de administración de datos.
