Buenas, @Lazaro000:

En primer lugar tendrías que solicitar un token personal, en su documentación tienes un enlace para hacerlo. Es solo enviar un correo solicitando un token.

Después, ese token hay que enviarlo mediante una cabecera en el nodo HTTP. Si te fijas en la siguiente imagen:

en este caso n8n utiliza la credencial predefinida por cabecera. En este caso esa casilla la tienes vacía, tendrías que crear esa crendencial con el token que te proporcionen.

La API solicita que el nombre de la cabecera de autenticación sea la de la imagen anterior (x-api-key), debajo debes poner el token.

Efectivamente, hay otra API. El endpoint sería https://apidatos.ree.es/datos/mercados/precios-mercados-tiempo-real añadiento los parámetros de fechas y demás, en su documentación tienes más detalles.

Cabe destacar que estas APIs son para mercados eléctricos de España.

Espero haberte ayudado, un saludo!
