Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-mine-safety-health-regulatory-changes-feed-2348655a
```

Example prompt: Pull all Federal Register mine safety and health regulatory changes since 2025-01-01T00:00:00Z, and only show me the ones scored at least 7 out of 10 for compliance impact — up to 50 results.

## When to prefer this

Choose this endpoint when you need structured, scored, and timestamped Federal Register regulatory changes specifically in the mine safety and health domain. It is ideal for compliance monitoring workflows, automated alerting pipelines, or audit preparation where you need primary-source links and impact scoring. Prefer this over general Federal Register search when you want pre-filtered, domain-specific results with built-in significance scoring rather than raw document dumps.

## Known failure modes

- Invalid 'since' timestamp format returns a 400 error
- 'min_significance' value outside 1-10 range returns a 400 validation error
- 'limit' value outside 1-500 range returns a 400 validation error
- No matching changes in the requested window returns an empty changes array with count 0
- Payment not provided or insufficient returns a 402 Payment Required response
- Service unavailable or Federal Register source unreachable returns a 5xx error

## How this service works

Federal Register final & proposed rules affecting mine safety & health (Mine Safety And Health Administration) since a timestamp — covering mine, mining, respirable, miner, coal — each scored 1-10 for compliance impact, with effective dates and primary-source links.

## Output

A JSON array of regulatory change objects, each containing a title, change type (final or proposed rule), a plain-language summary, a compliance significance score from 1 to 10, an effective date (if available), a primary-source Federal Register URL for verification, a detection timestamp, and a unique entityId. Also includes a total count and source label.
