Rate limit

A rate limit is a cap on the number of requests a client may issue within a time window, enforced by a provider to protect shared infrastructure from overload.

Providers cap requests per second or per window so one client cannot starve others; exceeding the cap returns a throttling error you handle by backing off and retrying. Rate limits shape how you design bulk work — paging eth_getLogs by block range, spacing trace calls — so you stay within the ceiling. On our platform, usage is also metered as credits against your prepaid balance across tiers C1 to C4, so cost and throughput are tracked from one accounting model rather than separate quotas.
