How this service works
Pay-per-call services for the agent economy: a webhook the moment a Monero or Zcash payment lands at your address (view-key only), single-fact x402 data APIs, a paid public notice board, a stablecoin gas paymaster and a permissionless Ethereum block builder. No account, no API key — pay in USDC on Base or in XMR/ZEC.
Output
A JSON object with an as_of_ms timestamp and arrays of risk-scored records per category: malicious_spenders (addresses harvesting ERC-20 approvals), risky_tokens (honeypots, fake wrappers, fee-on-transfer/sell-revert traps), live dangling approvals, and bleeding bots — each row includes its risk score and the contributing score factors.
Example use cases
Wallet security check before trading
“Before I swap tokens on this DEX, can you check Seneschal for any risky approvals or honeypot tokens I should avoid? Give me anything with a risk score over 60.”
Monitor active approval exploits
“Pull the malicious spenders feed from Seneschal and alert me if any of the addresses I've previously approved are now on the bleeding bots or harvester list.”
DeFi bot token safety screening
“I'm about to trade a new token — run it through Seneschal's honeypot detector and show me if it has any fee-on-transfer traps, sell-revert blocks, or fake wrapper issues.”
Technical details
Endpoint
GEThttps://api.seneschal.space/v1/premium/counter-mev?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time, mainnet-sourced threat intelligence specifically about ERC-20 approval exploits, honeypot tokens, and MEV-related wallet-drain patterns. Prefer it over generic token scanners when you need pre-scored, multi-category risk data with granular score factors rather than simple blocklists. Best for DeFi security agents, wallet protection systems, or trading bots that need to screen approvals and tokens before execution.
