Data Sources and Limits

Last updated: 2026-07-15

This page and the application use the same versioned registry. It explains which providers back each mode, how old data may be, what fallbacks exist, and whether a value is an observation, cache, inference, or simulation.

Machine-readable source registry · Current mode health and freshness

Provider, product and license proper names remain unchanged so they can be found precisely and checked against the primary source.

Interpretation

Observation is a provider-issued measurement or catalog record.
Cache preserves the original observation time; receiving it again does not make it new.
Inference is a derived estimate and is shown as degraded.
Simulation is synthetic and is never presented as an observation.

Data right now

Current API records available to each mode. A globe may render a smaller performance-limited subset and labels that distinction explicitly.
