How this service works
Decision procedure for an autonomous agent that must settle x402 or MPP micropayments onchain: select gas limits and priority fees, decide when to batch multiple micropayments into one transaction, choose between ERC-4337 paymaster and native sponsorship, forecast base fee across time windows, and bound total settlement cost for a spend session.
Output
A structured decision procedure brief (prose and/or structured fields) covering: gas limit and priority fee selection logic, batching thresholds for micropayments, ERC-4337 paymaster vs native sponsorship selection criteria, base fee forecasting across time windows, and cost bounding strategies for a spend session. Includes metadata like generation source (llm/reasoning/deterministic), model used, topic, and ISO-8601 timestamp.
Example use cases
Gas limit selection for micropayment agent
“My agent is about to settle a series of x402 micropayments onchain — can you give me the decision procedure for choosing the right gas limits and priority fees so I don't overpay or get stuck?”
Batching threshold decision for spend session
“I'm running an autonomous agent that makes frequent small onchain payments and I need to know when it makes more sense to batch multiple micropayments into one transaction versus sending them individually — walk me through the decision logic.”
Paymaster vs native sponsorship choice
“My agent needs to decide between using an ERC-4337 paymaster or native sponsorship for covering gas on x402 settlements — what's the decision procedure for picking the right option and keeping total session cost within budget?”

Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/agent-onchain-settlement-cost-engineering-decisiWhen to prefer
Choose this endpoint when an autonomous agent needs structured, actionable guidance for optimizing onchain settlement costs specifically for x402 or MPP micropayments on EVM chains. Prefer this over generic gas estimation APIs when the agent needs a holistic decision procedure covering batching, paymaster selection, and fee forecasting together, rather than a single gas price lookup.
Side effects
- Payment required but not provided — returns 402 with payment details
- Invalid topic override format — may return default procedure
- Service temporarily unavailable — 5xx response
- Malformed request parameters — returns validation error
- LLM/reasoning generation failure — result may be missing 'brief' or 'procedure' fields
