How this service works
Deterministic pre-settlement decision procedure for an agent that is offered a token as payment, payout, collateral, or reward over x402 and must decide whether the token contract is safe to accept or interact with before any settlement. Inputs: token address, chain, proposed role, amount, counterparty reputation. Checks: contract type and upgradeability, ownership and mint authority (EOA admin vs timelock), buy-sell symmetry with a dust test (honeypot detection), fee-on-transfer tax traps,
Output
A structured response containing a boolean safety decision, a prose decision procedure brief explaining the reasoning for agents, checks on contract upgradeability, ownership and mint authority, honeypot buy-sell symmetry results, fee-on-transfer detection, and a generation timestamp.
Example use cases
Honeypot check before accepting reward token
“I'm about to receive 1000 tokens at contract 0xDEAD...BEEF on Ethereum as a yield reward — can you run the token safety decision procedure on it first and tell me if it's a honeypot or has any sell restrictions?”
Collateral token vetting for DeFi agent
“My agent is being offered token 0x1234...ABCD on Base as collateral for a lending position — please screen it for unsafe mint authority, upgradeability, and buy-sell asymmetry before we proceed.”
x402 payment token screening before settlement
“A counterparty with moderate reputation wants to pay me in token 0xAAAA...BBBB on Polygon for 250 units — run the pre-settlement safety check on it and tell me whether the contract is safe to accept over x402.”
Technical details
Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/agent-decision-procedure-for-pre-transaction-tokWhen to prefer
Use this endpoint when an AI agent is about to accept an unfamiliar token as payment, collateral, payout, or reward in an x402 or onchain context and needs a deterministic go/no-go safety check before settlement. Prefer this over generic contract explorers when you need an agent-ready decision procedure that covers honeypot detection, fee-on-transfer traps, mint authority risk, and upgradeability in a single call.
Side effects
- Token address not found on the specified chain — returns error with no result
- Unsupported chain — endpoint may return an error or incomplete analysis
- Rate limit or payment failure — 402 payment required response if unpaid
- Network timeout when performing dust test or onchain contract inspection
- Ambiguous or incomplete token metadata leading to inconclusive safety result
