[3-LEG] Local three-leg environment chain, one location (?loc=): leading air quality (AQI) -> current precipitation, rain and 30-day dry-wet -> realized nearest river stage and streamflow (confirmation gate). A chain, not one reading: confidence = how many legs are lit, in order. Sources: EPA/CAMS, ERA5, USGS. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.25 per call.

Caveats

Things to know before drawing strong conclusions

  • · Calls and volume are 30-day cumulative figures from the source facilitator. Daily breakdowns are not yet available — see /methodology.
  • · Volume = price × calls. If the server publishes multiple price tiers, only the first accepts[] entry is used.
  • · "Last call" is what the source last reported, refreshed every 60 seconds.
