Selects a published emissions factor by activity, region and source edition. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age. This is neither legal advice nor customs advice.

Returns the latest instantaneous values at a USGS streamgage, together with what makes them readable. A stage of three point four feet means nothing on its own, so each value is placed against the station own record for the requested reference period: the minimum, median and maximum, and the percentile the current reading falls at. The reference period is stated with the comparison, because a percentile without a window is not a statistic.

Propagates a circular two-body orbit from altitude, inclination, RAAN, and initial orbital phase; rotates Earth at a fixed sidereal rate; and samples ground-station elevation. It ignores eccentricity, perturbations, epoch-dependent Greenwich angle, refraction, ellipsoid shape, terrain, and antenna masks, so it is a planning estimate rather than operational ephemeris.

Standardizes each supplied value against its supplied mean and standard deviation, flips markers whose favorable direction is lower, and computes a weighted composite mapped to a bounded 0–100 index. The references and weights come entirely from the caller; this is not a validated longevity score, diagnosis, prognosis or medical advice.

Computes the observed germination rate and a Wilson score interval from germinated and tested counts using a supplied normal critical value. It does not correct sampling bias, test vigor, identify disease or predict field emergence.

Providers each build their signing string differently — some sign only the body, others prepend a timestamp, an id, or a version marker in a fixed order — and getting that order wrong produces a mismatch that looks exactly like an attack. This checks the signature the way the named provider actually specifies, with constant-time comparison, and returns the string that was signed so a mismatch can be debugged instead of guessed at.
