# ZoningVerdict Rules API

> ZoningVerdict Rules API is a paid API for AI agents from zoningverdict.com, paid per call via x402, $0.01/call, status healthy (last checked 2026-10-14).

Returns independently reviewed, cited zoning ordinance rules for a given municipality, optionally filtered by district code and topic category.

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 zoningverdict-rules-api-cf0996f6
```

Example prompt: What does the Rochester Hills zoning ordinance actually say about ADUs in the R-1 district? I want the exact citation and source URL, not just a summary.

## When to prefer this

Use this endpoint when you need the actual text of a zoning ordinance with an authoritative citation and source URL, not just a database record or summary. Ideal when you need verified, human-reviewed interpretations of what a rule says (not just what's on file), with traceability. Best for the 64 covered municipalities across 6 states; check coverage before relying on it for other jurisdictions.

## Known failure modes

- Municipality slug not in the 64-municipality coverage set — returns empty or 404
- District code not found within the municipality — returns empty rules array
- Topic enum value misspelled or not matched — no results returned
- Municipality coverage gap — some districts or topics may not yet be reviewed
- Rate limit or payment failure via x402 — call not processed

## How this service works

Reviewed zoning rules for one published municipality, optionally narrowed by district and topic. Coverage: 64 municipalities in 6 states. Returns body_md, ordinance citation, source_url, pack_version, and last_reviewed_at. Positioning: Records tell you what's on file; ZoningVerdict tells you what the ordinance actually says, independently verified, with the citation. Responses include source citations and last-reviewed dates. Price: $0.01/call.

## Output

Returns a JSON object with a 'meta' block (municipality name, last_reviewed_at, pack_version, disclaimer) and a 'rules' array where each item contains district_code, topic, body_md (full Markdown text of the rule), citation (ordinance section reference), and source_url pointing to the original document — all independently verified by ZoningVerdict.
