GET https://aeml-x402.zeabur.app/gauge/calibrated · 1 observation
Add-on, calibrated units: normalized_index and pct_to_action so readings compare across stations. When the line has no calibration basis you get 422 with no_charge:true and reason:no-calibrated-for-this-line, and are NOT billed. Every record carries an offline-recomputable record_hash.

[BATCH+PROOF] All entities for one signal at their latest reading, with band, frequency_label and percentile columns so you can rank across stations and screen for the unusual in one call. Cross-station comparison is the point: one river gauge alone tells you little, 200 of them ranked by distance-to-action tells you a lot. Descriptive only, never a forecast or advice.
