To provide a quality of service to many users as possible, We have rate limiting policy for Vault API calls.
Minimum guaranteed requests
2 requests in every 0.25 seconds.
2 requests in every 0.25 seconds are always guaranteed as a minimum. The server will reject calls more than this limit if you try to send more.
Multiple requests in the same moment
11 Requests as maximum (Burst)
We provide a "burst" concept on the requests. So, in case of you need to send multiple requests at the same moment, You can call the server up to 11 requests as maximum. The server will reject calls more than this limit if you try to send more.
Total amount of requests allowed
400 calls / minute
The system doesn't allow to send more than 400 requests in a minute. If you exceeded this amount of calls, you'll be banned for 1 hour by the system and will be not allowed to send any requests during the ban period.
Whitelisting Vault IP
Vault might send multiple notifications if you have a high transaction volume on the blockchain. In order to prevent any firewall or rate limiting issues for webhook notifications you require to whitelist the Vault's IP address. The following IP address is the static IP address used by the vault for only outbound activities.
