## 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 new-rail-staged-exposure-and-exit-procedure-6407b3d4
```

Example prompt: Walk me through the staged exposure and exit procedure for adopting Algorand x402 as a new payment rail — I need guidance on funding caps, settlement finality checks, and when to fall back or exit.

## When to prefer this

Choose this endpoint when an AI agent needs structured, step-by-step guidance specifically for onboarding a new x402 payment rail with risk controls — particularly when staged funding caps, settlement finality verification, and explicit exit criteria are needed. Prefer it over generic payment risk advice when operating in the x402 ecosystem (e.g., Algorand x402) and needing operationally grounded decision logic rather than static documentation.

## Known failure modes

- Missing or invalid method parameter returns an error
- Payment not settled results in 402 response requiring x402 payment
- Unknown topic override may yield generic procedure output
- Service downtime or handler failure returns ok: false with no brief
- Rate limiting or repeated unpaid calls may be rejected

## How this service works

Decision procedure for agents adopting a newly operational x402 rail such as Algorand x402. Covers staged funding caps based on cumulative settled volume, settlement finality verification before cap escalation, fallback retention on existing rails, and explicit exit conditions when the new rail underperforms.

## Output

A JSON object containing decision procedure prose (brief and procedure fields) tailored to the staged adoption of a new x402 rail, including the topic, generation timestamp, and generation source (llm, reasoning, or deterministic). The brief provides actionable guidance covering funding cap stages, settlement finality gating, fallback retention logic, and underperformance exit triggers.
