## 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 federal-register-trucking-motor-carrier-regulatory-changes-6caf7540
```

Example prompt: Pull all Federal Register trucking and motor carrier regulatory changes since January 1, 2025 that have a compliance impact score of at least 7 — I want to make sure we haven't missed anything significant for our fleet compliance review.

## When to prefer this

Choose this endpoint when you need to monitor or audit recent Federal Register rulemaking specifically affecting commercial trucking, freight carriers, or motor vehicles — especially when you need compliance-severity scoring and direct links to primary sources. Prefer it over general news or legislative trackers because it surfaces both final and proposed rules with actionable impact scores, filtered to the transportation/trucking domain only.

## Known failure modes

- Invalid 'since' timestamp format returns a 400 validation error
- 'min_significance' outside 1-10 range returns a 400 error
- 'limit' outside 1-500 range returns a 400 error
- No changes found in the specified window returns an empty changes array with count 0
- Upstream Federal Register data unavailable may return 503 or stale results
- Payment not provided or insufficient returns 402 Payment Required

## How this service works

Federal Register final & proposed rules affecting commercial trucking & motor carriers (Federal Motor Carrier Safety Administration) since a timestamp — covering motor carrier, commercial driver, hours of service, cdl, trucking — each scored 1-10 for compliance impact, with effective dates and primary-source links.

## Output

A JSON object containing a count of matching changes, a source label, and an array of regulatory change objects each with: title, type (final/proposed rule), summary, significance score (1-10), effective date, detected-at timestamp, entity ID, and a primary-source URL linking to the Federal Register entry for verification.
