## 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 2s-io-b810a26c
```

Example prompt: Can you pull up all open HPD violations for the building at 123 West 125th Street in Manhattan — specifically any Class C immediately hazardous ones — so I can check the landlord's code enforcement history?

## When to prefer this

Use this endpoint when you need structured, filterable HPD violation data for NYC multi-family buildings — especially for tenant rights research, landlord background checks, code enforcement analysis, or real estate due diligence. Prefer this over generic NYC open data portals when you need a clean, agent-friendly API with per-call pricing and no authentication setup.

## Known failure modes

- No results returned if BBL or address does not match any HPD-registered building
- Invalid BBL format (must be exactly 10 digits) may return empty results or error
- classCode must be exactly A, B, or C — other values rejected
- offset/limit out of range returns 400 or empty set
- Address substring too vague returns many unrelated results
- Network or upstream HPD data unavailability returns 5xx

## How this service works

NYC Housing Preservation & Development (HPD) violations — every notice of violation issued at a multi-family building. Search by `bbl` (10-digit) or `address` (street_name substring). Filter by `classCode` (A=least severe, B=hazardous, C=immediately hazardous) and `currentStatusOnly=true` to limit to open violations. Each row carries violation id, building id, full address + apartment + story, inspection + approved + certify-by + correct-by dates, current status + status date, and the narrative NOV description. Use for landlord-history, code-enforcement, and tenant-rights agents.

## Output

A paginated list of HPD violation records for the queried building, each containing violation ID, building ID, full address with apartment and story, inspection/approved/certify-by/correct-by dates, current status and status date, and the full Notice of Violation narrative description. Results can be filtered to only open violations and to specific severity classes.
