## 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 novapath-signal-edition-query-78e1e8ac -d '<json body>'
```

Example prompt: Pull up to 10 fleet signals from the October 18 NovaPath edition, starting at offset 0, and include the source links and dated receipts.

## When to prefer this

Use this endpoint when you need to query static, curated signal records from the fixed October 18 edition across one of five specific verticals (construction, fleet, FDA device, FDA food recall, NY healthcare). Prefer it over live data sources when you need stable, citable records with source links and dated receipts for research, auditing, or reference purposes. Not suitable if you need live bids, real-time updates, or editions other than October 18.

## Known failure modes

- Requesting an edition other than 2026-10-18 will fail since only that fixed edition is supported
- Limit values outside 1–20 will be rejected by schema validation
- Offset values above 20,000 will be rejected
- Invalid vertical enum values will cause a validation error
- No live or real-time data is available; only static October 18 snapshot records exist
- Payment failure (0.3 USDC not received) will block access
