RoxyAPI bundles 18 domains and 258 endpoints on one flat plan and publishes a NASA JPL Horizons benchmark. Asterwise adds a permanent free tier, Rajju and Vedha vetoes, Lal Kitab and Varshaphal, and a median deviation of 0.046 arcseconds against the same reference.

By Asterwise

Facts about RoxyAPI were read from its own pages on 7 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

RoxyAPI puts 18 domains, 258 endpoints and 255+ MCP tools on one flat plan with no credit weighting, and publishes a NASA JPL Horizons benchmark with data and script. It has no free plan, no Dashakoot, Rajju or Vedha, no Lal Kitab or Varshaphal, and runs its own engine rather than Swiss Ephemeris. Asterwise has a permanent free tier, the deeper Vedic matchmaking set, and a median deviation against the same JPL reference of 0.046 arcseconds to RoxyAPI's 1.5.

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?AsterwiseRoxyAPI
The exact price of a callYes. $10 ÷ 10 = $1.00; $30 ÷ 50 = $0.60; $100 ÷ 300 = $0.33.₹59.98 or $0.78 (Starter); ₹20.00 (Professional, ₹9,999 for 500,000); ₹8.33 (Business, ₹24,999 for 3,000,000); one request is one quota unit on REST and MCP
What computes the positionsYes. Swiss Ephemeris with the full data files."Roxy Ephemeris", described by the vendor as an in-house engine using "analytical planetary theory"; the vendor states it does not use Swiss Ephemeris
How accurate the positions areYes: 80 positions checked against NASA JPL Horizons, median 0.046 arcseconds, raw data and script published.Yes: 210 positions across 21 charts (1879 to 2011) against NASA JPL Horizons DE441, run 2026-07-30: median 1.5 arcseconds, 95th percentile 11.2, maximum 16.6; data and Python script published (MIT)
The full API contractYes, public at api.asterwise.com/openapi.json.Yes, OpenAPI 3.1 at roxyapi.com/openapi.json (licence marked Proprietary)
Try it without payingYes. 500 calls a month, no card, does not expire.No free API plan published; four paid tiers only. The vendor's FAQs say "No credit card required for testing" and that the interactive API reference returns real responses; a keyless API call returned HTTP 401 on the date checked. A keyless docs-only MCP server exists

Where a cell says not published, it means we could not find the fact on the vendor's pages on 7 September 2026. It is not a claim that the fact is bad, only that you cannot check it before you build.

Choose RoxyAPI if

  • You want one key for tarot, numerology, Human Design, BaZi, feng shui, I Ching and more alongside astrology.
  • You want output in Turkish, German, Spanish, Hindi, Portuguese, French, Russian or Chinese.
  • You need a PHP, Go or C# SDK, or a WordPress plugin and drop-in UI components.

Choose Asterwise if

  • You want to try before paying: 500 free calls a month with no card; RoxyAPI publishes no free plan.
  • You need Dashakoot, Rajju and Vedha vetoes, Papasamyam or Porutham; RoxyAPI's document has Ashtakoot and Manglik only.
  • You need Lal Kitab, Varshaphal, Yogini, Ashtottari or Char dasha; none appear in RoxyAPI's OpenAPI document.
  • You want Swiss Ephemeris with the full data files and a published check against NASA JPL Horizons with a median of 0.046 arcseconds; RoxyAPI's own benchmark against the same reference reports 1.5.
  • You want signed responses and a Python or TypeScript SDK generated from the OpenAPI document.

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 7 September 2026.
