# Agent Decision Procedure for No-Facilitator Settlement Rails (Nano x402 v2, XRPL Direct, Algorand Direct) > Agent Decision Procedure for No-Facilitator Settlement Rails (Nano x402 v2, XRPL Direct, Algorand Direct) 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 brief helping agents choose between no-facilitator settlement rails (Nano x402 v2, XRPL direct, Algorand direct) and facilitator rails, covering trust tiering, settlement proof verification, refund/dispute absence, and cost floor honesty. ## Facts - Endpoint: GET https://k2so-8080.on.ascii.dev/api/services/agent-decision-procedure-for-no-facilitator-sett - Price: $0.002/call - Payment: x402 - Status: unknown - Last checked: 2026-09-13 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/agent-decision-procedure-for-no-facilitator-settlement-rails-nano-d077e094 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_UYlT44BmWrIjOc9YlwzPy Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability agent-decision-procedure-for-no-facilitator-settlement-rails-nano-d077e094 ``` Example prompt: Give me the blunt decision procedure for when my agent should use a no-facilitator rail like Nano x402 v2, XRPL direct, or Algorand direct versus a facilitator rail — covering trust tiering, how to verify settlement proofs, and what the cost floor trade-offs actually are. ## When to prefer this Choose this endpoint when an agent needs a structured, blunt decision framework for selecting between no-facilitator settlement rails (Nano x402 v2, XRPL direct, Algorand direct) and facilitator-backed rails. It is the right choice when trust tiering, settlement proof verification, absence of refund/dispute mechanisms, and cost floor comparisons are the core concerns. Prefer this over generic x402 fee-ranking endpoints when the agent needs procedural guidance rather than a fee table, and over general blockchain comparison tools when the context is specifically agentic x402 payment rail selection. ## Known failure modes - Payment not made or insufficient: endpoint returns 402 Payment Required before delivering content - Invalid method (e.g. POST): only GET, HEAD, DELETE are accepted per schema - Topic override yields ambiguous or out-of-scope brief if not closely related to settlement rails - LLM generation failure: generationSource may fall back to deterministic with reduced quality - Stale or cached brief if generatedAt timestamp is old ## How this service works Paid agent-facing brief on agent decision procedure for no-facilitator settlement rails (Nano x402 v2, XRPL direct, Algorand direct) vs facilitator rails: trust tiering, settlement proof verification, refund/dispute absence, cost floor honesty · Build a decision procedure or schema for: agent decision procedure for no-facilitator settlement rails (Nano x402 v2, XRPL direct, Algorand direct) vs facilitator rails: trust tieri-0. Blunt decision procedure, not marketing. ## Output Returns a JSON object containing a prose decision procedure brief (the 'brief' and 'procedure' fields), the topic evaluated, the service slug, an ISO-8601 generation timestamp, the model used, and the generation source (llm, reasoning, or deterministic). The brief is blunt and agent-oriented, covering trust tiering, settlement proof verification, refund/dispute absence, and cost floor honesty for no-facilitator vs facilitator rail selection. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET", "HEAD", "DELETE" ], "type": "string" }, "queryParams": { "type": "object", "properties": { "meta": { "enum": [ "0", "1" ], "type": "string", "description": "Set to 1 for free metadata JSON (no payment required)" }, "topic": { "type": "string", "description": "Optional topic override for the decision procedure" } } } }, "additionalProperties": false }, "output": { "type": "object", "required": [ "type" ], "properties": { "type": { "type": "string" }, "example": { "type": "object", "title": "agent decision procedure for no-facilitator settlement rails (Nano x40 paid response", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "ok", "paid", "service", "provider", "result" ], "properties": { "ok": { "type": "boolean" }, "paid": { "type": "boolean" }, "result": { "type": "object", "required": [ "ok", "service" ], "properties": { "ok": { "type": "boolean", "description": "Handler success" }, "brief": { "type": "string", "description": "Decision procedure prose for agents" }, "model": { "type": "string" }, "topic": { "type": "string" }, "service": { "type": "string", "description": "Service slug" }, "procedure": { "type": "string" }, "generatedAt": { "type": "string", "description": "ISO-8601 timestamp" }, "generationSource": { "enum": [ "llm", "reasoning", "deterministic" ], "type": "string" } } }, "payment": { "type": "object", "properties": { "code": { "type": "string" }, "payer": { "type": "string" }, "detail": { … (truncated) ``` ## More - Live health (JSON, refreshed every minute): https://www.zero.xyz/c/agent-decision-procedure-for-no-facilitator-settlement-rails-nano-d077e094/health.json - [Zero catalog index](https://www.zero.xyz/llms.txt) - [Other services from k2so-8080.on.ascii.dev](https://www.zero.xyz/host/k2so-8080.on.ascii.dev/llms.txt)
