# Knockorno

Official or silence.

Ask once. If a public machine door exists, you get a hashed receipt. If it does not, you get no. Not a company. Not a seal.

Knockorno only fetches official public GET doors. It will not scrape a login, mint a stamp, or invent a number. Assistants add this door by URL. Humans knock on the page. We do not list in a catalog.

Doors on the page: heating oil, ENERGY STAR model, flood zone, NWS observation, USGS streamgage, NYS contractor registry, certified deed. Certified copies and apostilles are no. NWS is an observation receipt, not a forecast, not a warning. USGS is latest streamgage observation, not a flood forecast. Contractor registry is public-work registration, not a home-improvement license.
