Rate limits
In addition to the method whitelist, the following rate limiting is in place:
User starts out with 1,000 credits
Credits are reset 60 seconds after the first request
Single RPC requests costs 2 credits
Batch RPC requests costs 1 credit per message in batch
These limits are visible in the X-RateLimit-Limit, X-RateLimit-Remaining and X-RateLimit-Reset headers.
In addition to the rate limits that are transparent with the headers, there is a limit of 25,000 credits per 12 hours, and an absolute maximum of 2,500 POST requests per 5 minutes.
If you surpass these limits your requests will be throttled.
The rate limits of our free service is subject to change at any time without notice.
