## 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://dot-prequalified-contractor-records.pages.dev/d/n/cles.json` — the name-index keys
- `https://dot-prequalified-contractor-records.pages.dev/d/n/<key>.json` — names starting with that key -> [identifier, name, city, state, type]
- `https://dot-prequalified-contractor-records.pages.dev/d/r/<fragment>.json` — records; fragment = hash of the identifier: 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 identifier.
- No individuals.
- Two States so far. Illinois work categories are shown as IDOT's own codes. Phone numbers, e-mail addresses and bid addresses in the State files are not shown. A prequalification is not a contract.
- This site ranks no one.
