We are excited to share that we have improved Malicious Address API to provide more transparency and insight into flagged addresses. We added new fields:

• Source: where the malicious report originates (Hackbounty, Blockmate, CryptoScam DB,...)
• Description: Get details on why an address is flagged as malicious (e.g., Trust trading scam site)

📢 Now, when you check an address, you’ll have better context on potential threats! Stay safe!

Example response:

{  
  "status": "invalid",  
  "address": "0x002bf459dc58584d58886169ea0e80f3ca95ffaf",  
  "source": "CryptoScamDB",  
  "description": "Trust trading scam site"
