## 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-6ba4fb55
```

Example prompt: Can you fetch the standard cross-rail adjudication evidence bundle export procedure so I know the canonical ordering, hash chaining, and redaction policy for assembling a dispute bundle that covers the payment rail, identity rail, messaging rail, and merchant artifacts?

## When to prefer this

Choose this endpoint when an AI agent or compliance system needs authoritative procedural guidance for assembling multi-rail dispute evidence bundles (payment, identity, messaging, merchant) and needs the canonical ordering, hash-chaining, redaction policy, and export envelope specification in a single machine-readable brief. Prefer this over general legal or compliance databases when the specific context involves x402-based agent merchant transactions on Base.

## Known failure modes

- Payment not provided — returns HTTP 402 requiring USDC micropayment via x402 protocol
- Invalid or unsupported HTTP method — schema only allows GET, HEAD, DELETE
- Malformed query parameters — unrecognized topic override or meta flag value may be ignored or cause an error
- Service unavailable on k2so.wrong.systems — endpoint may be intermittently offline
- LLM generation failure — generationSource may fall back or result in empty brief field

## 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

Returns a structured object containing a prose decision procedure brief for agents, the service slug, generation timestamp, generation source (llm, reasoning, or deterministic), and optionally a topic label — all describing how to assemble, order, hash-chain, redact, and format a cross-rail adjudication evidence bundle.
