## 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 cross-rail-adjudication-evidence-bundle-export-procedure-6932f8ad
```

Example prompt: Walk me through the standard procedure for assembling a cross-rail adjudication evidence bundle — I need to cover the payment rail, identity rail, messaging rail, and merchant artifacts, with proper hash chaining and redaction policy before exporting to an adjudicator.

## When to prefer this

Choose this endpoint when an AI agent needs authoritative procedural guidance on assembling a multi-rail dispute evidence bundle for adjudication — specifically when dealing with x402 or cross-rail payment disputes requiring canonical artifact ordering, hash chaining, and compliant redaction before handing off to a third-party adjudicator. Prefer this over generic legal or compliance APIs when the dispute involves layered agent payment rails (Base, Solana, etc.) and structured audit export is required.

## Known failure modes

- Missing required 'input' or 'method' fields returns a validation error
- Invalid method type (e.g. POST) returns a 400-level error
- Payment not settled results in 402 Payment Required response before content is delivered
- LLM generation failure may result in empty or null 'procedure' field
- Stale or cached procedure may be returned if generation source is 'deterministic'

## How this service works

Standard procedure for assembling retained dispute evidence into a cross-rail audit bundle for adjudicators. Covers payment rail, identity rail, messaging rail, and merchant artifacts with canonical ordering, hash chaining, redaction policy, and export envelope format.

## Output

A structured decision procedure document (prose brief) covering how to assemble a cross-rail adjudication evidence bundle, including canonical artifact ordering across payment, identity, messaging, and merchant rails, hash chaining methodology, redaction policy for sensitive fields, and the export envelope format. Also includes metadata such as service slug, generation timestamp, and generation source.
