## 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 locus-rental-registration-check-60be38b6 -d '<json body>'
```

Example prompt: Can you check the official rental registration status for 1531 Belmont Ave, Seattle, WA 98122 — I want to know if it's actively registered, how many licensed units it has, and whether there are any enforcement records on file?

## When to prefer this

Choose this endpoint when you need official, source-cited rental registration or housing-enforcement records for a specific building address in Seattle, Minneapolis, or New York City. It is ideal for tenant due diligence, investor compliance checks, or pre-lease verification where exact-building matching matters. Prefer it over general property lookup endpoints when the specific goal is rental licensure or registration status. Do not use it as a legal compliance determination — results are source-bounded reference data.

## Known failure modes

- Address outside covered jurisdictions (Minneapolis, NYC, Seattle) returns a not-covered or uncovered coverage status
- Ambiguous or malformed address may fail to match or resolve to wrong parcel
- No registration records found returns no_records status — not a legal confirmation of non-registration
- Enforcement data not published by source for some jurisdictions returns not_published_by_source status
- Result is source-bounded and explicitly not a legal-rental or compliance decision — misuse as such is a user-side failure
- Address too short (under 5 chars) or too long (over 200 chars) will fail input validation

## How this service works

Exact-building rental registration or license records for Minneapolis, New York City, and Seattle, plus each source's published housing-enforcement components. Returns recorded registration status, dates, units, record ids, query limits, citations, and verify-next questions. Excludes owner, contact, property-name, apartment, narrative, and nearby-address fields. A checked no-match is source-bounded, not a legal-rental or compliance decision.

## Output

Returns a structured JSON object including: jurisdiction and matched address details, registration status (records_found, no_records, not_covered, etc.), individual registration records with record IDs, source status, licensed unit counts, expiration dates, source citations and URLs, enforcement component status and records, condemned/boarded record counts, coverage status, observation metadata (match method, result limits, records examined), and caveats clarifying scope limitations.
