Welcome MesoWest Users

Explore the Weather API

Build queries, explore endpoints, and visualize real-time weather observations from thousands of stations.

Welcome to our interactive Weather API demo page! Here you can take a test run of our Weather API using the Query Builder, learn more about the types of queries you can make in the Endpoints section, view station selection parameters, see examples, and read frequently answered questions. Get started below!

Weather API Query Builder

Use our query builder tool to test out our API services and parameters. Follow the prompts below to see how the API responds to various inputs. You’ll need an API token to run specific examples. You can get a token by going to customer.synopticdata.com, creating an account, and navigating to Data Credentials.

How to Use the Query Builder

The blue sections in the left-hand column below provide descriptions of the API services and inputs.

The light areas are interactive. Make selections and fill in values here. Once you have looked through all the possible arguments and refinements, click the request button to call the API.

We use several icons to assist you in understanding our API arguments. They indicate the category of the task that the argument performs.

A form of authentication, usually an API token, sometimes an API key.
Filter returned stations or observations. Remember that all filters are cumulative.
Change the information returned (e.g. change output units)
Change the behavior of the API (e.g. list tokens instead of create)
Change the order of returned stations

1. Enter your API Token

Enter the API token associated with your Synoptic account. Make sure to use a token generated from your API key — not the key itself. You can generate tokens at customer.synopticdata.com. Don't have an account? Sign up for a free 14-day trial and gain access to Synoptic's Weather API.

Your token authenticates every request to the API. As you configure parameters below, your token will be included automatically in the generated URL.

Your API Request URL

As you configure your request below, your API URL is built automatically and displayed here. When you are ready, click the request button to execute it live against the API and see the response.

2. Select your service

Which API service would you like to try out? Think of a service as what kind of information you want to get from the API. Do you want metadata? Do you want a timeseries of observations?

You can only utilize one service at a time (per request) from the API, so we'll start by picking which service you want to try/use.
