## 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 x402-quote-change-report-ad2f0781 -d '<json body>'
```

Example prompt: Can you run a quote-change report comparing our stored public quote observations to see what changed between the two dates — use public data class with nonpersonal metadata only?

## When to prefer this

Use this endpoint when you need to compare two dated stored unpaid quote snapshots and receive a structured change report, especially when working with public or synthetic nonpersonal data. Prefer this over real-time quote feeds or live pricing APIs when you need historical diff analysis on previously recorded observations rather than current prices. Best suited for audit, reconciliation, or drift-detection workflows where continuous uptime is not assumed.

## Known failure modes

- Input exceeds 32 KiB limit — request rejected
- dataClass value not in allowed enum (public, synthetic) — validation error
- nonpersonalMetadata not set to true (const) — schema validation failure
- No stored quote observations found for the specified dates — empty or error response
- Output exceeds 65 KB — truncation or rejection
- Stale or missing observations due to sparse sampling — incomplete diff

## How this service works

Compare dated stored unpaid quote observations; sparse samples are not continuous uptime, buyer calls or delivery. Public/synthetic nonpersonal input only; 32 KiB input, 65 KB output. Result retention: 24 hours; minimal receipt metadata: 90 days. No model calls or factual certification.

## Output

Returns a structured report (up to 65 KB) comparing two dated stored quote observations, highlighting what changed between them — including changed values, timestamps of observations, and difference metadata. Results are retained for 24 hours; minimal receipt metadata is kept for 90 days.
