How this service works
Single-fact wallet-safety check: is address X a known approval-drainer (malicious spender harvesting ERC-20 approvals to transferFrom-drain them — the JaredFromSubway $7.5M pattern) or a honeypot/bait token? Returns {flagged, as, risk_score, risk_band, top_flags} from the same live mainnet scanner + scorer as the premium counter-MEV feed. Check before you approve.
Output
Returns a JSON object with: flagged (boolean indicating malicious), as (classification label e.g. 'approval-drainer'), risk_score (numeric), risk_band (e.g. 'HIGH', 'LOW'), top_flags (array of strings describing detected issues), addr (the queried address), present (whether it's in the database), as_of_ms (timestamp), and detail_endpoint (URL for full detail).
Example use cases
Pre-buy honeypot check for token
“I'm about to buy this token at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 — can you quickly check if it's a honeypot or has any malicious flags before I put money in?”
Safe spender approval screening
“I got a DeFi prompt asking me to approve 0x68b3465833fb72A70ecDF485E0e4C7bD8665Fc45 to spend my WETH. Can you scan that address and tell me its risk band and whether it's known to drain approvals?”
Suspicious contract risk lookup
“Someone in a Telegram group shared a contract address 0xd9Db270c1B5E3Bd161E8c8503c55cEABeE709552 and told me to approve it — can you check if it's flagged as a drainer or scammer and what the risk score looks like?”
Technical details
Endpoint
GEThttps://api.seneschal.space/v1/q/address-riskWhen to prefer
Use this endpoint when an AI agent or wallet UI needs a fast, single-address pre-approval safety check before a user grants ERC-20 token approval to a spender contract, or before buying an unfamiliar token. It is powered by the same live mainnet scanner as Seneschal's premium counter-MEV feed, making it more current than static blocklists. Prefer this over generic token screeners when the threat model is specifically approval-draining or honeypot attacks on Ethereum mainnet.
Side effects
- Address not in database — returns present: false with low/no risk score
- Invalid address format (not 0x…) — likely 400 error
- Payment not included or insufficient — 402 Payment Required
- Network timeout querying live mainnet scanner — 503 or timeout
- Address is newly deployed and not yet indexed — may return low risk despite being malicious
