Rate limits
At Ntropy, we implement a rate-limiting policy based on the computational cost of each endpoint and its possible use case. The rate limiting is calculated per API key, independent of the source of the request (i.e., IP).
For transaction enrichment, we have a system of credits for wherein each transaction deducts one credit from your API key. You can accumulate at most 100,000 credits which are refilled at a rate of 1000 per second. Additionally, there is a system to limit the number of concurrent enrichment operations running at any given time. You can have up to 10 concurrent enrichment operations.
If you are hitting rate limits of our API with your workloads, please contact us to increase them for your API key.
