Google Fonts

Google Fonts is a free, open-source library of over 1,500 font families maintained by Google, widely used to embed web-ready typography into websites and applications. The Google Fonts Developer API (also known as the Webfonts API) provides programmatic access to the complete metadata catalog served by Google Fonts, returning structured JSON data that includes font family names, available style variants (weights and italics), supported Unicode subsets and scripts, font file URLs, designer attribution, and category classification (serif, sans-serif, display, monospace, handwriting). Organizations use the API to automate font catalog auditing, build custom font pickers, synchronize font metadata into internal asset management systems, track the addition of new font families over time, and feed typography data into design toolchains or dashboards.

Prerequisites​

The Google Fonts Developer API uses API key authentication. You will need a Google Cloud project with the Google Fonts Developer API enabled and an API key generated for that project.

Create a Google Cloud Project and Enable the API​

  1. Sign in to the Google Cloud Console using your Google account.

  2. Click Select a project in the top navigation bar, then click New Project.

  3. Enter a descriptive name for your project (for example, "Nexla Fonts Integration") and click Create.

  4. Once your project is created, navigate to APIs & Services > Library in the left sidebar.

  5. Search for Google Fonts Developer API in the API Library search box.

  6. Select Google Fonts Developer API from the search results and click Enable to activate the API for your project.

Generate an API Key​

  1. After enabling the API, navigate to APIs & Services > Credentials in the left sidebar.

  2. Click Create Credentials and select API Key from the dropdown. Google Cloud generates a new API key immediately and displays it in a popup dialog.

  3. Copy the API key and store it securely — you will need it when configuring the credential in Nexla.

  4. Optionally, click Edit API key to apply restrictions to the key:

    • Under API restrictions, select Restrict key and choose Google Fonts Developer API from the list. This limits the key to only the Fonts API, reducing risk if the key is ever exposed.

    • Under Application restrictions, you may optionally restrict usage to specific IP addresses or HTTP referrers for additional security.

  5. Click Save to apply any restrictions.

Important

Store your API key securely and never share it publicly. If you believe your key has been compromised, regenerate it immediately from the Google Cloud Console under APIs & Services > Credentials.

The Google Fonts Developer API allows up to 10,000 requests per day per API key. For most font catalog and metadata use cases this limit is more than sufficient. Additional details are available in the Google Fonts Developer API documentation.

Authenticate​

Create a credential in Nexla​

  1. After selecting the data source type, click the Add Credential tile to open the Add New Credential overlay.

  2. Enter a name for the credential in the Credential Name field and a short, meaningful description in the Credential Description field.

  3. Enter the Google Fonts API key you generated in the Google Cloud Console in the API Key field. This key authenticates all requests Nexla makes to the Google Fonts Developer API and must correspond to a project that has the Google Fonts Developer API enabled.

    The API key is associated with your Google Cloud project. Ensure the key belongs to a project where the Google Fonts Developer API is enabled. For steps on generating or locating your key, see the Google Fonts Developer API documentation.

  4. Click the Save button at the bottom of the overlay. The newly added credential will now appear in a tile on the Authenticate screen during data source creation.

Use as a data source​

To create a new data flow, navigate to the Integrate section, and click the New Data Flow button. Select the Google Fonts API connector tile, then select the credential that will be used to connect to the Google Fonts API instance, and click Next; or, create a new Google Fonts API credential for use in this flow.

Endpoint templates​

Nexla provides a pre-built template that can be used to rapidly configure a data source to ingest data from the Google Fonts catalog. Select the endpoint from which this source will fetch data from the Endpoint pulldown menu. The available endpoint template is listed in the expandable box below.

List Webfonts

Retrieves the complete list of font families currently served by the Google Fonts Developer API, including all available style variants, supported Unicode subsets, font file download URLs, designer attribution, and category classifications (serif, sans-serif, display, monospace, handwriting). Use this endpoint to ingest a full snapshot of the Google Fonts catalog for auditing, font picker tooling, or design asset management.

  • Optionally, select a sort order for the returned font families using the Sort parameter. Available sort options are:

    • alpha — Sort families alphabetically by name.
    • date — Sort by the date the font family was added to Google Fonts, with the most recently added families first.
    • popularity — Sort by usage popularity across the web, with the most widely used families first. This is the default sort order used by the Google Fonts website.
    • style — Sort by the number of available style variants, with families offering the most variants first.
    • trending — Sort by families currently seeing the most growth in usage.

  • Optionally, select a font file capability using the Capability parameter to control what font file URLs are included in the response. Available options are:

    • CAPABILITY_UNSPECIFIED — Returns static TTF font file URLs (default behavior when no capability is specified).
    • WOFF2 — Returns WOFF2 (Web Open Font Format 2) font file URLs, which are compressed and optimized for web delivery.
    • VF — Returns variable font file URLs instead of static fonts instantiated at standard weights, where available.
    • FAMILY_TAGS — Includes classification tags that apply to the entire font family in addition to the standard font metadata.

The Google Fonts Developer API returns all font families in a single response — there is no pagination. Each record in the Nexset produced from this source corresponds to one font family and includes its variants, subsets, files, and metadata. For additional details about the API response structure, refer to the Google Fonts Developer API documentation.

Once the selected endpoint template has been configured, click the Test button to the right of the endpoint selection menu to retrieve a sample of the data that will be fetched. Sample data will be displayed in the Endpoint Test Result panel on the right, allowing you to verify that the source is configured correctly before saving.

Manual configuration​

Google Fonts API data sources can also be manually configured to send requests to any valid Google Fonts Developer API endpoint, including alternate query parameters or API versions not covered by the pre-built template. Select the Advanced tab at the top of the configuration screen, and follow the instructions in Connect to Any API to configure the API method, endpoint URL, date/time and lookup macros, path to data, metadata, and request headers.

The Google Fonts Developer API uses GET requests at the base URL https://www.googleapis.com/webfonts/v1/webfonts (for example, https://www.googleapis.com/webfonts/v1/webfonts?sort=popularity). Do not include the key query parameter in the URL — Nexla automatically appends your API key from the configured credential to every request.

The response is a single JSON object with a top-level items array and no pagination; enter $.items[*] in the Set Path to Data in Response field to treat each font family as an individual record. To retain the top-level kind field (webfonts#webfontList) alongside each record, specify its location in the Path to Metadata in Response field.

Once all of the relevant settings have been configured, click the Create button in the upper right corner of the screen to save and create the new Google Fonts API data source. Nexla will now begin ingesting data from the configured endpoint and will organize any data that it finds into one or more Nexsets.
