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 200K 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.
