Why do we have rate limits?​

Rate limiting is used by the API to prevent abuse and ensure a reliable experience for all consumers.

What are the rate limits for the 0x APIs?​

The current limit for the Free Tier of our APIs is approximately 1 Request Per Second (RPS) and 100K API calls per month globally. You can view rate limits for all tiers on the pricing page.

How are rates calculated?​

The following is shared to help your team to maximize your app setup. The example below uses the 1 RPS Free Tier limit; however, the same logic applies to all tiers.

  • The 1 RPS is 1 call per chain (aka per endpoint)
  • The 1 RPS is per fixed 1 second window; in other words, the API has fixed 1 second windows and will allow 1 call per chain any where within that 1 second window
  • You can view your current usage and limits on the 0x API Dashboard.
