  utilpeek: offline geocoding over the GeoNames cities15000 table. Input: either `place` alone or `lat` and `lon` together. `place` matches cities of 15,000+ people offline ("City" or "City, CC" with an ISO country code or a US state code); no match is a 404 place_not_found (not charged). Cities only (no street addresses). Typically under 0.1 s (first call up to 1 s). Price: USD 0.001. Free: 10 utilpeek calls per IP per UTC day. Data: GeoNames (geonames.org) cities15000, CC BY 4.0; credit it when you show or republish it (the `attribution` field carries the text).

  weatherpeek: hourly weather forecast for a point or a city. Input: either `lat` and `lon` together, or `place` alone, plus optional `hours`. Returns `location`, `updated_at`, `units` and `hourly` rows, plus `cached` and `attribution`. `place` matches cities of 15,000+ people offline ("City" or "City, CC" with an ISO country code); no match is a 404 place_not_found (not charged). Upstream errors are a 5xx and are not charged. Typically 0.1-2 s. Price: USD 0.002. Free: 5 weather forecasts per IP per UTC day. Data: MET Norway and GeoNames, both CC BY 4.0; credit them when you show or republish it (see `attribution`). Forecasts are numerical weather model output and can be wrong: not for safety-critical decisions (aviation, marine, severe-weather warnings); use official services for those.

• 2026-10-09satellite_passeschangeddescription
  before

  skypeek: Predict satellite passes over a location. Returns the passes of a satellite (default the ISS) over a point in the next 1-3 days: start, highest and end times with azimuth and elevation, duration, and whether the pass is visible to the eye. Input: `lat`, `lon`, optional `alt_m`, `norad_id`, `days`, `min_elevation` and `visible_only`. SGP4 predictions, not observations, from CelesTrak orbital elements (only derived pass times are returned; no endorsement by CelesTrak implied). Satellites: CelesTrak's 'stations' and 'visual' groups plus NOAA 15 / 18 / 19; another NORAD id is a 422 (not charged). At most 40 passes. A cold orbital-data cache or an upstream outage can be a 503 (not charged; retry). Typically under 1 s; with a cold orbital-data cache up to a minute or more (a 503 when too slow, not charged: retry). Price: USD 0.002. Free: 5 skypeek calls per IP per UTC day.

• 2026-10-09aurora_forecastchangeddescription
  before

  skypeek: Aurora forecast: the chance of visible aurora at a location in the next 30-90 minutes. Returns the chance (0 to 100 percent) of visible aurora overhead at a point from NOAA SWPC's OVATION model for the next 30-90 minutes, with the current Kp, the Sun's altitude and whether it is dark enough. Input: `lat` and `lon`. Data: NOAA Space Weather Prediction Center (public domain), a derived copy, not an official NOAA product; no endorsement by NOAA or the National Weather Service is implied. The model assumes a dark, clear sky: cloud, moonlight and light pollution are not modelled. Cached up to 10 minutes. An upstream outage is a 503 upstream_unavailable (not charged). Typically under 1 s cached, a few seconds on a refresh. Price: USD 0.001. Free: 5 skypeek calls per IP per UTC day.
