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-food-safety-manufacturing-rules-feed-9c839c26
```

Example prompt: Show me all Federal Register food safety and manufacturing rule changes since January 1, 2025 that have a compliance significance score of at least 7 — include effective dates and links to the original documents.

## When to prefer this

Use this endpoint when you need machine-readable, significance-scored Federal Register food safety and manufacturing rule changes with primary-source links for a specific time window — especially for compliance monitoring workflows, alerting pipelines, or audit trails. Prefer over manual Federal Register search when you need structured data with impact scoring and need to filter by date and significance threshold.

## Known failure modes

- Invalid or missing 'since' date format returns a 400 validation error
- min_significance out of range (not 1-10) returns a 400 error
- limit exceeding 500 returns a 400 error
- No matching results returns an empty changes array with count 0
- Payment not provided or insufficient returns a 402 Payment Required
- Upstream Federal Register source unavailable causes 503 or timeout

## How this service works

Federal Register final & proposed rules affecting food manufacturing & safety (Food And Drug Administration) since a timestamp — covering food safety, food label, food additive, foodborne, dietary supplement — each scored 1-10 for compliance impact, with effective dates and primary-source links.

## Output

A JSON object containing a count of matching changes and an array of regulatory change records, each with a title, type (final/proposed rule), plain-English summary, significance score (1-10), effective date, detectedAt timestamp, entityId, and a primary-source URL linking to the Federal Register document.
