How this service works
Wallet intelligence: EOA-vs-contract, ETH+USDC balance, tx count, activity/risk flags.
Output
Returns a JSON object with an array of heuristic safety flags (empty if none), the total transaction count, ETH balance, USDC balance, a boolean indicating if the address is a smart contract, and an activity level string (e.g. 'active', 'inactive').
Example use cases
Example prompt
“Can you run a rug-pull safety check on the wallet 0xAb5801a7D398351b8bE11C439e05C5B3259aec9b and tell me if there are any suspicious flags, what the ETH and USDC balances are, and whether it's a contract or a regular wallet?”
Technical details
Endpoint
POSThttps://eltociear-tokenguard.hf.space/walletWhen to prefer
Use this endpoint when you need a quick, low-cost ($0.005 USDC) heuristic safety signal on an ERC-20 wallet or token address before interacting with it — especially for DeFi due diligence, bot-driven token screening, or pre-trade risk checks. Prefer this over full audit services when speed and cost matter more than exhaustive analysis.
Side effects
- Invalid or malformed wallet address returns an error
- Public RPC rate limiting may cause timeouts or stale data
- Address with no on-chain history may return zeroed balances and empty flags
- Network congestion may delay RPC response
- Heuristics may produce false positives or miss sophisticated rug pulls
