Introduction

API Reference

The Frogcast API provides an easy way to integrate your weather forecast data with any external system.

The API is organised around REST semantics, uses JSON to encode objects, and relies on standard HTTP codes to signal operation outcomes.

The Frogcast API doesn't support bulk updates. You can work on only one object per request.

we release new versions and tailor functionality. Log in to see docs customized to your version of the API, with your key and data.

If you find any features missing or have any suggestions, please contact us.

Free Usage and Paid Subscription

Registration is free and access is immediate.
New users are granted a single location, regardless of their geographic area.
Once these free requirements are exhausted, users will be offered a paid subscription and can upgrade their locations.
See our pricing and plans page for more details.

Authentification

Frogcast uses a simple token-based authentication.
All API requirements must be authenticated and made via HTTPS.

Your token is automatically generated when you register on the app.frogcast.
Once you sign in, you can access it here https://app.frogcast.com/fr/api/
The token must be added in the header.

Key

Value

Authorization

Token {your token}

Your API token has the same privileges as your user account, so be sure to keep them secret!
Do not share your secret API keys in publicly accessible areas.
API requests without authentication will fail.

Errors

Frogast uses conventional HTTP response codes to indicate the success or failure of an API request.

In general:

Codes in the 2-- range indicate success.
Codes in the 4-- range indicate an error that failed given the information provided (e.g., a required parameter was omitted, a charge failed, etc.).
Codes in the 5-- range indicate an error with Frogcast's servers.

Set of requests

All the requirements are presented in this section.
You will find everything you need to create your first request very simply.

In the FROGCAST API, a Locationt is called a System.

Main API url https://api.frogcast.com/api/v1/

GET

Weather forecasts

1. Frogcast by request

Once you’ve taken out a Frogcast by request subscription, you can obtain forecasts by querying the forecast endpoint with the latitude and longitude parameters you require.

API endpoint https://api.frogcast.com/api/v1/forecast/

2. Frogcast by location

If you’ve opted for Frogcast by location and created your first location, the corresponding UUID {system_uuid} can be found in your account.
With this parameter you can start using the API right away.

To get the forecast for a location, extend the endpoint URL using the UUID of the location in question (available on your account).
The API supports several additional settings that the user can adjust to modify the retrieved forecast.
The available parameters are described in the Settings section.

API endpoint https://api.frogcast.com/api/v1/forecast/{system_uuid}/

GET

All fields

To get a detailed list of all variables available on the Frogcast platform.

Each variable is identified by it's "id" field. Use that value when you want to request a new variable for a location for example

API endpoint https://api.frogcast.com/api/v1/allfields/

GET

Unused fields

Gives you a list of fields that are not unused in your {system_uuid} location.
Allows you to quickly retrieve the missing "ids" fields to add them to your PATCH requests

API endpoint https://api.frogcast.com/api/v1/system/{uuid}/get_unused_fields/

POST

Location

Frogcast by location only

To add a location.

The ability to add one or more of the locations depends on your subscription contract.

The parameters of Location must be specified in a POST request with following requirements.
Requested parameters:

title : limited to 128 characters
name : limited to 32 characters
Latitude and longitude coordinates must be specified in decimal degrees (°).
is_favorite : favorite status. Must be specified in boolean.
is_active: Designates whether this object should be treated as active. Unselect this instead of deleting the location.Must be specified as a boolean.
subscribed_fields (or weather forecasts variables) must be specified by their respective id; the correspondance between the variables names and their id can be retrieved via this request.
location : Localisation of the system. Latitude and longitude coordinates must be specified in decimal degrees (°).
altitude is in meters (m).
tags :string denoting a tag for this system, for example a project name or a category.

API endpoint https://api.frogcast.com/api/v1/system/
