🔏Rate Limits & API Key

Learn about our rate limits and how to obtain and configure an API key.

Our API is free to integrate but rate-limited.

If not authenticated per API key, the default rate limits will be applied:

• 200 requests in 2 hours to /quote or /routes

• 20 rpm (request per minute) for all other requests combined

If authenticated via API key, the rate limits are as follows:

• 200 * 120 requests in 2 hours to /quote

• 200 RPM for all other requests

If you're using the API directly, you can configure the API key as described here.

If you're using our SDK, you can configure the API key as described here.

If you're using the Widget, you should not use an API key.
