URL Scanning API

1. Scans URLs and returns warnings if a URL indicates a possible phishing attempt. Warnings can be easily mapped for end-users. Examples include the URL being recently created or containing a wallet drainer
2. Verify that you are on an official web3 URL. Our allowlist, which contains 300+ verified web3 domains such as OpenSea, MetaMask, Coinbase, Bored Ape Yacht Club, and more.

Simulation APIs

Supports transactions and signatures

A note about both services

Our simulation APIs automatically integrate URL scanning as long as you provide an origin URL for the request. This allows us to provide the deepest insights into the safety of a transaction. For example, Set Approval For All is a perfectly reasonable signature for a website like OpenSea to ask for in order to list your NFTs. But if an unverified website is asking Set Approval for All, there is strong reason to believe that website could have malicious intent.
