If you know your application will query data only from specific smart contracts or address sources, please add those addresses to your Contract Address Allowlist.
When an address is added to the allowlist, any API requests with query addresses beyond that will be rejected.
The following interfaces use contract address parameters:
/v1/contracts/contract_address/events /(event)|(events)/contract/contract_address /(event)|(events)/contract/[a-zA-Z0-9]+/[a-zA-Z0-9]+ /(event)|(events)/contract/[a-zA-Z0-9]+/[a-zA-Z0-9]+/[a-zA-Z0-9]+ /walletsolidity/triggerconstantcontract /wallet/triggersmartcontract /wallet/triggerconstantcontract

Any compatible request methods with non-allowlisted addresses alone as parameters will be rejected.
