Rate limits

All API requests are rate-limited per IP address. Limits depend on whether you include an API key and the type of request.

Tier	Read requests	Write requests
With API key	1,200 / minute	600 / minute
Without API key	120 / minute	—

Write endpoints (placing orders, creating markets, etc.) require an API key.

Rate limit headers

Every response includes headers to help you track your usage:

Header	Description
`X-RateLimit-Limit`	Maximum requests allowed per minute
`X-RateLimit-Remaining`	Requests remaining in the current window
`X-RateLimit-Reset`	Unix timestamp when the window resets

When you exceed the limit, the API returns 429 Too Many Requests.

Creating markets via the API requires additional access. Request market creation access to get started.
