the problem usually isn’t missing facts. it’s that null means different things in different counties — no flood map vs no flood risk, wrong parcel, owner fields

the problem usually isn’t missing facts. it’s that null means different things in different counties — no flood map vs no flood risk, wrong parcel, owner fields that don’t map cleanly.
if the API returns absent/failed instead of making the model guess, that’s actually a really good design choice.
curious how often those cases show up on normal residential parcels vs the messier commercial/infill sites.
- anshchokshi 1mo agoin our fetch api every field comes with ok / absent / failed. it never returns a bare null and lets you/your agent assume. credit is not charged in case the api returns absent value. for ask api, the null is shown to the model as value: NULL plus an instruction — "acknowledge the gap explicitly. do not state, estimate, or infer a value for it from general knowledge or from the coordinate." so models never make any data up. empty fields are rare on houses and commercial lots (~5%) and common on rural land (~29%), but on rural land empty usually means "nothing's there," while on houses and lots it usually means "the county didn't publish it.
