Facts about FreeAstrologyAPI were read from its own pages on 5 September 2026; every row in the full table below carries its source, and the page ends with how to report an error.

The short answer

FreeAstrologyAPI is the cheapest paid option here and its free plan allows more calls per month than ours. It covers planets, divisional charts, panchang, Vimshottari and Ashtakoot, with SVG charts. Asterwise covers Dashakoot, Rajju and Vedha, KP, Lal Kitab, Varshaphal, four dasha systems, Western transits and synastry, numerology and tarot, and ships an MCP server, SDKs and an OpenAPI document.

What you can verify before you write a line of code

An astrology API is a promise about astronomy, coverage and price. The fastest way to compare two of them is to ask what each lets you check in advance.

Can you check this before signing up?AsterwiseFreeAstrologyAPI
The exact price of a callYes. $10 ÷ 10 = $1.00; $30 ÷ 50 = $0.60; $100 ÷ 300 = $0.33.$0.30 (Mercury), $0.20 (Venus), $0.15 (Saturn)
What computes the positionsYes. Swiss Ephemeris with the full data files.not published
How accurate the positions areYes: 80 positions checked against NASA JPL Horizons, median 0.046 arcseconds, raw data and script published.not published
The full API contractYes, public at api.asterwise.com/openapi.json.not published
Try it without payingYes. 500 calls a month, no card, does not expire.50 requests a day, 1 request a second

Where a cell says not published, it means we could not find the fact on the vendor's pages on 5 September 2026. It is not a claim that the fact is bad, only that you cannot check it before you build.

Choose FreeAstrologyAPI if

  • You need exactly what it lists, planets, vargas, panchang, Vimshottari, Ashtakoot, and price per call is everything.
  • You want chart SVGs in North Indian, South Indian and wheel styles.
  • You need very high burst rates on a paid plan.

Choose Asterwise if

  • You need matchmaking beyond Ashtakoot: Dashakoot, Rajju and Vedha vetoes, Papasamyam, Kerala and Tamil Porutham.
  • You need KP, Lal Kitab, Varshaphal, Yogini, Ashtottari or Char dasha, Western transits, synastry, returns or progressions.
  • You want an MCP server for Claude and Cursor, typed SDKs, and an OpenAPI document; FreeAstrologyAPI publishes none.
  • You want to know the engine and its accuracy before you build; FreeAstrologyAPI publishes neither.
  • You want your free calls without a daily cap: 500 a month, usable in one burst.

Start with 500 free calls a month, no card, no expiry. Connect the MCP server to Claude or Cursor in one line, or install the Python or TypeScript SDK. See pricing or connect the MCP server.

How to read the prices

Where a vendor publishes both a monthly price and a monthly call quota, the price per 1,000 calls is the first divided by the second, and the arithmetic is shown under the row. Where a vendor sells credits that cost different amounts per endpoint, or publishes no quota, no per-call price is given, because none can be derived.

How this page stays honest

Every statement about another vendor on this page is a statement about what that vendor's public pages said on the date shown, not a statement about the quality of its calculations or its service. Where a page did not say, the row reads not published, and that means only that we could not find it. Vendors change prices and features; verify anything that matters to you on the vendor's own page before you decide.

Report an error. Email support@asterwise.com with the row, the correct fact and a public page that shows it. We check it within five business days, change the row, and record the change in the corrections log on this page with the date.

Corrections log. No corrections have been requested for this page since it was published on 5 September 2026.
