Agent Decision Procedure for Pre-Signature EVM Transaction Simulation
x402
Agent Decision Procedure for Pre-Signature EVM Transaction Simulation is a paid API for AI agents from k2so-8080.on.ascii.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).
Returns a blunt, LLM-generated decision procedure telling autonomous agents which EVM transaction simulator to use per chain, how to classify revert risk, and what to do when simulation fails or is unavailable before signing.

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 prose decision-procedure brief generated by an LLM or reasoning engine covering: which EVM transaction simulator to use per chain and context, how to classify revert risk, how to handle approval and slippage checks within the simulation, and explicit fallback instructions when simulation reverts or is unavailable. Response also includes metadata such as model used, generation source (llm/reasoning/deterministic), ISO-8601 timestamp, and service slug.
Example use cases
Simulator selection before DeFi swap
“I'm about to submit a Uniswap swap transaction on Ethereum mainnet — tell me which simulator my agent should use to check for reverts and how to interpret slippage risk before signing.”
Revert risk triage for batch agent execution
“My agent is queuing several EVM transactions across Base and Arbitrum. Give me the decision procedure for classifying revert risk on each chain so I know which ones to simulate first and which are low-priority.”
Fallback policy when simulation is unavailable
“My simulation endpoint is returning errors right now — what should my agent do? Should it skip and sign anyway, retry, or abort? I need the standard procedure for handling unavailable simulation before settling.”
Technical details
Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/agent-facing-decision-procedure-for-pre-signaturWhen to prefer
Choose this endpoint when an autonomous agent needs a structured, opinionated decision procedure for EVM transaction simulation prior to signing — especially when the agent lacks internal policy for simulator selection across chains, revert-risk triage, or simulation failure fallback. Prefer over generic documentation when you need a blunt, agent-consumable procedure rather than marketing prose. Best suited for agents operating on EVM chains (Base, Ethereum, Arbitrum, etc.) that must make real-time signing decisions under uncertainty.
Side effects
- Payment not settled — returns 402 requiring x402 micropayment before content is delivered
- Simulation topic unavailable — brief may be generic if topic override is not recognized
- LLM generation failure — ok field returns false with no brief content
- Rate limiting or provider downtime on ascii.dev infrastructure
- Malformed query params — schema validation error if unsupported params are passed
