Estimated time: under 2 minutes. This guide assumes you already have an Uniblock project. If not, follow the Uniblock Quickstart Guide first.
1

Copy your API key

Open your Uniblock dashboard and navigate to your project. Your API key is displayed on the Overview page — click the copy icon next to it.
2

Open the API Tester

In the left sidebar of your project, go to Endpoints → API Tester. This opens the Uniblock Explorer in a new tab.
3

Authorize your API key

On the Explorer page, click the Authorize button at the top. Paste your Uniblock API key into the X-API-Key field and click Authorize, then Close. All subsequent requests in this session will use your key.
4

Select an endpoint

Find and expand the /token/metadata endpoint. Click Try it out to enable the input fields.
5

Execute the request

Example values are pre-filled in the required fields. You can use them as-is or enter your own chainId and token address. Click Execute to send the request.
6

View the response

The response body appears below the Execute button with a 200 status code and the token metadata JSON. That’s it — you’ve made your first authenticated Unified API call.

Continue on to the other guides in the Unified API section for more detail on authentication, analytics, and auto-routing features.
