Rate Limits & API Key

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

Last updated 29 days ago

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, /routes or /stepTransaction

  • 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, /routes or /stepTransaction

  • 200 RPM for all other requests

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

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

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

You can obtain your API key by registering on .

If you encounter CORS issues after implementing the API key, please check this
