## 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-dispute-evidence-retention-lifecycle-brief-6812b3f3
```

Example prompt: Give me the full decision procedure for how long I need to keep payment receipts, quotes, and communication logs for x402 dispute settlement — including when to archive, when to prune, what hashes and timestamps to preserve, and how to respond if a counter-party requests evidence.

## When to prefer this

Choose this endpoint when an autonomous agent needs authoritative, actionable guidance on evidence retention obligations specific to x402 payment disputes — particularly when the agent operates in a multi-party settlement environment and needs clear archive/prune thresholds and counter-party response protocols. Prefer over general legal or compliance databases when x402-specific procedural guidance is needed without human legal consultation.

## Known failure modes

- Payment required but not provided — returns 402 with payment instructions
- Invalid query parameter value for meta field — returns validation error
- Service temporarily unavailable — upstream LLM or reasoning engine down
- Malformed request — missing required method or type fields

## How this service works

Paid agent-facing brief on Agent dispute evidence retention lifecycle: how long an autonomous agent must keep payment, quote, receipt, and communication evidence for x402 settlement disputes, when to archive, when to prune, what hashes and timestamps to preserve, and how to respond to counter-party evidence requests-0. Blunt decision procedure, not marketing.

## Output

A detailed prose decision procedure ('brief') covering: minimum retention periods for payment records, quotes, receipts, and communications in x402 disputes; when to move evidence to archival storage; when pruning is safe; which cryptographic hashes and ISO-8601 timestamps must be preserved; and a step-by-step procedure for responding to counter-party evidence requests. Also includes metadata such as topic, model used, generation source, and generation timestamp.
