Para qué sirve
Toda respuesta HTTP lleva un código de tres dígitos que indica al cliente qué ha ocurrido: 2xx para éxito, 3xx para una redirección, 4xx para un error del cliente y 5xx para un fallo del servidor. Esta herramienta incluye los códigos registrados ante la IANA junto con una descripción en lenguaje llano, para que puedas comprobar qué significa un código o encontrar el adecuado que devolver sin salir de tu editor.
Cómo se usa
- Escribe un código de estado, su nombre o una palabra clave como "límite de solicitudes".
- Opcionalmente, filtra los resultados a una sola categoría (1xx–5xx).
- Lee la explicación breve del código coincidente.

Preguntas frecuentes
- ¿De dónde procede esta lista?
- De una tabla local con los códigos registrados ante la IANA, que cubre todos los que suele devolver una API web o una interacción con el navegador. No realiza ninguna llamada a un servidor.
- ¿Cuál es la diferencia entre 401 y 403?
- 401 Unauthorized significa que la solicitud necesita credenciales de autenticación válidas; 403 Forbidden significa que el servidor sabe quién eres pero se niega a autorizar la acción de todos modos.
- ¿Por qué existe el 418?
- "Soy una tetera" procede de una RFC de broma del Día de los Inocentes de 1998. Rara vez se usa en serio, aunque alguna API lo emplea como guiño.
