How this service works
Paid routing endpoint: feed a payment intent (amount, optional rail filter, reliability floor) and get every eligible rail quoted with expected fee, total cost, reliability, finality, a cheapest-rail recommendation, and float sizing for pooled settlement. Machine-readable JSON computed from the provider's measured per-rail fee index.
Output
A machine-readable JSON object listing every eligible payment rail with: expected fee, total cost, reliability score, finality estimate, a cheapest-rail recommendation, and float sizing for pooled settlement. Includes a prose decision brief for agents, generation source, and ISO-8601 timestamp.
Example use cases
Minimize fees on large USDC transfer
“I need to send 500 USDC — can you check all available payment rails and tell me which one is cheapest right now, including the fee breakdown and expected finality time?”
Reliability-gated payment routing for agent
“My agent is about to make a payment of 75 USDC and I need it to go through reliably — find all rails that meet at least a 99% reliability floor and recommend the best one.”
Float sizing for pooled settlement desk
“We're running a pooled settlement operation and need to know how much float to hold — can you pull the current rail quotes for a 1000 USDC intent and give me the float sizing recommendation?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/live-multi-rail-x402-routing-optimizerWhen to prefer
Choose this endpoint when an AI agent or autonomous system needs to programmatically select and optimize a payment rail before executing a transfer — especially when cost, reliability, and finality all matter. It is purpose-built for multi-rail x402 environments and returns machine-readable structured JSON suitable for downstream automation, unlike narrative or single-rail advisory endpoints.
Side effects
- Invalid or missing payment amount returns an error JSON
- Rail filter specifies an unsupported or unavailable rail, yielding an empty eligible-rail set
- No rails meet the specified reliability floor, returning an empty recommendation
- Payment required (x402) but client fails to attach payment, blocking the response
- Provider fee index temporarily unavailable, resulting in a stale or failed quote
