Rate limits & quotas

What is enforced, and how to pace yourself.

Rate limits and quotas

Limits are per token, with an hourly ceiling per account so extra tokens are not a way to go faster. Any authenticated response carries X-RateLimit-Limit and X-RateLimit-Remaining, so you can pace yourself without waiting for a rejection. A 429 adds Retry-After.

A 401 is the exception: authentication fails before the throttle runs, so those carry no rate-limit headers.

Reads 300 per minute
Component writes 60 per minute
Asset uploads 30 per minute
Project creation 10 per hour, per account
All requests 1000 per hour, per account

Separately, writes are bounded by the designer's own account: their storage quota and their project cap. Call /me to read both before a large sync.
