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 JSON object containing a 120+ word plain-prose decision procedure brief (field: `brief`/`procedure`) that an AI agent can follow step-by-step to evaluate a token contract's safety before a transaction. Includes the LLM model used, generation source (llm/reasoning/deterministic), ISO-8601 timestamp, topic, service slug, provider name (K-2SO), and payment confirmation fields (payer, transaction hash, selfPay flag).
Example use cases
DeFi bot pre-trade token screening
“My trading agent is about to buy a newly listed token — can you generate the decision procedure it should follow to screen the token contract for safety before the swap goes through?”
Wallet agent allowlist enforcement
“I'm building a wallet agent that needs to decide whether to approve a token contract interaction — give me the standard decision procedure it should run through before approving any new contract.”
On-chain risk gate for agent pipeline
“Before my autonomous agent signs any transaction involving an unfamiliar token, I need a structured screening procedure it can follow to catch rug pulls, honeypots, and other contract-level risks — what's the recommended decision process?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-decision-procedure-for-pre-transaction-tokWhen to prefer
Choose this endpoint when an autonomous agent needs a ready-made, LLM-generated decision procedure specifically for pre-transaction token contract safety screening — particularly in x402 pay-per-call pipelines on Base where no account setup is desired. Prefer over static checklists when you want reasoning-model-quality prose that adapts to topic overrides. Best suited for agents operating in DeFi or on-chain contexts that need structured risk guidance without building their own screening logic.
Side effects
- HTTP 402 returned if USDC payment not yet settled — agent must pay exact $0.002 USDC and retry with PAYMENT-SIGNATURE header
- Payment signature mismatch or replay results in 402 rejection
- Invalid or unsupported HTTP method returns error
- LLM generation failure may result in ok:false with empty brief
- Network timeout on Base blockchain settlement delays retry loop
- meta=1 returns free metadata JSON but no decision procedure content
