How this service works
Agent-facing brief specifying a deterministic procedure for selecting a cross-rail settlement layer (Base, Solana, or XRP Ledger) for x402 agent payments. Focuses on decision logic, not marketing.
Output
A JSON object containing a plain-prose decision procedure (120+ words) describing how an agent should select among Base, Solana, and XRP Ledger for x402 settlement, along with metadata including the generation source (llm, reasoning, or deterministic), model used, ISO-8601 timestamp, topic, and service slug.
Example use cases
New agent payment rail onboarding
“My agent is about to make its first x402 payment and I'm not sure whether to route it through Base, Solana, or XRP Ledger — can you walk me through the decision procedure so I pick the right rail from the start?”
Multi-rail agent switching logic
“I'm building an agent that needs to dynamically choose its settlement rail depending on context — give me the deterministic procedure for selecting between cross-rail x402 options so I can wire it into my routing logic.”
Non-EVM rail evaluation for agent payments
“I want to understand when my agent should prefer XRP Ledger or Solana over Base for x402 settlements — can you fetch the cross-rail selection procedure so I can evaluate the non-EVM options properly?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/cross-rail-settlement-selection-procedure-for-agWhen to prefer
Choose this endpoint when an agent needs a clear, prose-formatted decision framework for routing x402 payments across Base, Solana, and XRP Ledger rails. Prefer it over generic documentation when you need a deterministic, agent-consumable procedure rather than marketing content. Especially useful when building multi-rail payment routing logic or onboarding to x402 for the first time.
Side effects
- Payment not included — returns 402 with payment instructions
- Invalid query parameter values (e.g. meta not '0' or '1') — schema validation error
- Service temporarily unavailable — 5xx response
- Topic override not recognized — may return generic procedure
