Returns hourly surface concentrations from the CAMS European air-quality ensemble for a point in the cached DACH and Central Europe area. Available pollutants are CO, NO2, NO, O3, PM2.5, PM10 and SO2. Values come from the nearest 0.1 degree model cell and are labelled as a regional forecast rather than a street-level sensor reading. The local cutout is refreshed independently of paid calls, so Copernicus processing latency is not passed to the caller.

Sums enhancement_ppm×pixel_area, multiplies by wind speed, plume orientation, and a caller-supplied conversion factor, and reports the resulting proxy and optional kg/h estimate. It does not retrieve satellite data, remove background, solve atmospheric transport, determine source location, or validate the conversion factor.

Takes a kind 9735 receipt directly or fetches it from relays by event id, then runs eight named checks and reports each one separately with its reason. The receipt signature and the signature of the zap request enclosed in the description tag are verified per BIP-340. The invoice is decoded and its amount is compared against the amount tag of the zap request, since those two can disagree and only the invoice was payable.

Airdrop Sybil Score analyses only the evidence supplied by the caller. It does not claim to query a chain, identify a legal status or replace an independent audit. Missing signals lower confidence and are listed explicitly; every classification includes the exact thresholds used.

Parser-blocking script budget audit fetches current public evidence from the supplied target and evaluates the documented criterion. It returns the observation, threshold, verdict, exact evidence source, limitations and a mode-specific action. The check is passive: no login attempt, payload injection, exploit, purchase, form submission or load test is performed.

Continuous load is the sum of the running watts of all appliances marked as simultaneous. The surge check adds the largest single starting surge on top of the continuous load, which is the case that trips an inverter; simultaneous starts of two motors are reported separately as a second figure. Starting factors and power factors are design rules of thumb per appliance class and are stated in the response, they are not device data.
