More from Truth Bear & similar services
Truth Bear · Gauge Ruler
api.truthbear.co
Add-on, the official ruler: the band and threshold ladder published by the source agency, its classification, and distance-to-action. NOT every line has an official ruler - pure market quotes do not. When it does not, you get 422 with no_charge:true and reason:no-ruler-for-this-line and you are NOT billed. Never a bag of nulls you paid for. Every record carries an offline-recomputable record_hash. $0.0050 per call.
Truth Bear · Gauge
api.truthbear.co
[SIGNAL+PROOF] One official signal record for any signal_id and entity: current reading against the OFFICIAL threshold ladder (band, distance-to-action) plus a 5-year same-season percentile so you can tell routine from unusual. 180+ signals across macro, weather, hazard, shipping, filings, crypto and lifecycle lines. Free coverage check first at /gauge/coverage. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.01 per call.

No data -> 422 no_charge, not billed. $0.25 per call.
