[BATCH+PROOF] All entities for one signal at their latest reading, with band, frequency_la

[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. No data -> 422 no_charge, not billed. $0.09 per call.
