Example use cases

Example prompt

Technical details

Endpoint

GEThttps://mpp.orthogonal.com/precip/api/v1/cloud-cover-hourly?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need hyperlocal, site-specific hourly cloud cover data at a precise GPS coordinate — particularly useful for solar irradiance estimation, agricultural planning, drone operations, or any time-sensitive application requiring granular sky condition data at sub-regional resolution. Prefer this over general weather APIs when precision at a specific point matters more than broad regional forecasts.

Side effects

Invalid or missing latitude/longitude returns a 400 error
Requested time range outside available historical or forecast window returns an error or empty result
Location in an unsupported geographic region may return no data
API authentication failure returns a 401 unauthorized error
Rate limit exceeded returns a 429 error
