How this service works
Paid agent-facing brief on Agent-facing decision procedure for pre-signature EVM transaction simulation: when an autonomous agent must simulate a transaction before signing/settling it, which simulator to use per chain and context, revert-risk classification, approval and slippage checks inside the simulation, and what to do when a simulation reverts or is unavailable.. Blunt decision procedure, not marketing.
Output
A JSON object containing a plain-prose decision procedure brief (120+ words) tailored to pre-signature EVM transaction simulation, including the model used, generation source (llm/reasoning/deterministic), topic, service slug, ISO-8601 generation timestamp, and payment confirmation metadata.
Example use cases
Pre-signing safety check for DeFi agent
“My DeFi trading agent is about to submit a swap transaction on Base — can you generate a decision procedure brief it should follow before signing to avoid approving risky or malicious calls?”
Smart contract call validation workflow
“I'm building an autonomous agent that interacts with smart contracts. Give me a decision procedure it should run every time it's about to sign a contract call, so it doesn't accidentally approve something harmful.”
Custom topic: NFT mint transaction approval
“Generate a decision procedure brief for an agent deciding whether to sign an NFT mint transaction on an EVM chain, focusing on the specific risks around mint contracts and gas estimation.”

Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-facing-decision-procedure-for-pre-signaturWhen to prefer
Choose this endpoint when an autonomous AI agent needs a structured, prose-format decision framework for evaluating EVM transactions before signing, particularly in x402 micropayment-native agent architectures where per-call USDC billing is acceptable. Prefer this over static rule sets when you want an LLM-generated, contextually reasoned procedure that can be topic-overridden for specific transaction types.
Side effects
- HTTP 402 returned if payment not settled — agent must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Invalid or missing method type causes schema validation failure
- Topic override may produce off-topic or low-quality brief if the string is ambiguous
- Service may return generationSource=deterministic if LLM is unavailable, potentially lower quality
- Network or provider downtime at k2so.wrong.systems results in connection errors
