## 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-x402-unhappy-path-dispute-adjudication-escalation-procedure-6165029f
```

Example prompt: Walk me through the full decision procedure for escalating an x402 payment dispute to a third-party adjudicator — specifically how to frame the dispute question, assemble the evidence bundle, and record the binding outcome when proof alone hasn't resolved things.

## When to prefer this

Use this endpoint when an AI agent operating in the x402 payment ecosystem encounters a payment dispute that cannot be resolved by on-chain proof alone and needs a structured, actionable escalation procedure. Prefer this over general dispute guides when you specifically need the framing, evidence bundle, and adjudicator submission steps in a machine-readable decision brief. It complements the sibling cross-rail evidence bundle export endpoint but focuses on the decision logic rather than the export format.

## Known failure modes

- Payment not included or rejected (402 response) — agent must pay 0.002 USDC via x402 before content is returned
- Invalid or malformed query parameters return an error response
- LLM generation failure may result in ok:false with no brief field populated
- Network timeout on the ascii.dev host
- Topic override produces irrelevant or off-topic procedure if poorly specified
