## Access points

Every HTML page has a Markdown twin at the same path with the `.md` extension. Example: `/how-to-read/` -> `/how-to-read.md`. Links inside the Markdown files already point to the twins.

Search index, served as JSON with open CORS:

- `https://ny-contractor-registry-records.pages.dev/d/n/cles.json` — the name-index keys
- `https://ny-contractor-registry-records.pages.dev/d/n/<key>.json` — names starting with that key -> [certificate, name, city, state, expiration]
- `https://ny-contractor-registry-records.pages.dev/d/r/<fragment>.json` — certificate records; fragment = hash of the certificate number: h = 0, then for each character h = (h*31 + character code) modulo 4096; in hexadecimal on 3 digits
- `/sitemap.xml` — every page

These paths are **version 1** and will not change without notice. Bulk access, an availability guarantee or a change feed goes through `/pro/`.

## What this site is NOT

- This is not the official register and does not replace consulting it.
- Holding a licence is the minimum legal requirement, not a quality mark.
- One record per certificate of registration; every certificate in the file is Active.
- The compliance answers are those held in the registry, not findings of this site.
- Not found is not 'unregistered': the file is a snapshot.
- This site ranks no one.
