What it does
The specific capability behind this listing, and where to get it.
Astronomy calculations for any place and date: sun and moon rise/set times, planet positions and visibility, Mercury and Venus apparition events, solar and lunar eclipses, lunar phases, dark-sky observing windows, and place lookup. Eleven tools over a 29-endpoint REST API, covering 1700-2200. Streamable HTTP, no install. Tool calls need a CycleCalcs API key from RapidAPI (the Basic plan is free); browsing the tool list needs nothing. Astronomy, not astrology.

Pricing & plans
Observed public pricing for Astronomy, benchmarked against comparable providers. Plans, tiers, history and scenario below.
$5 /mo
The current price sits below the comparable median.
$5 sits below the observed Pro flat range ($24.65–$33.35) — around the 25th percentile of observed prices. It reads as a value play; make sure the margin still works.

Is Astronomy good value?
How its price compares with genuinely comparable providers.
Below the comparable median for its buyer tier.
Basis: Pro flat plans at the same billing unit (3 providers), USD monthly, pricing observed 2026-08-11. The Pro plan ($5/mo) sits 82.8% below that median of $29. Thin evidence: fewer than five comparable providers, so treat the position as indicative. Other cohorts on this page (niche-wide tier peers, nearest products by capability) are labelled where they appear.
Compared with Weather Data API
Positioned against the observed p25 / median / p75 of comparable providers at the same buyer tier and billing unit (the basis is stated with each verdict above). See the plans above for the percentile and its cohort size, and the full niche market for peers.
