Asterwise vs Prokerala Astrology API

Prokerala publishes a thorough OpenAPI document and serves twenty languages. Asterwise charges per call instead of per credit, computes four dasha systems, and runs an official MCP server.

By Asterwise

Facts about Prokerala Astrology API 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

Prokerala publishes a thorough OpenAPI document, serves more than twenty languages and can match 500 profiles in one call. What it does not do is tell you what a call costs: credits per endpoint range from 10 to 20,000, so the same ₹999 buys anywhere from fifty calls to a hundred thousand. Asterwise charges per call, publishes what it computes with, and runs an official MCP server.

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?AsterwiseProkerala Astrology API
The exact price of a callYes. $10 ÷ 10 = $1.00; $30 ÷ 50 = $0.60; $100 ÷ 300 = $0.33.₹9.99 per 1,000 credits on Ruby; a per-call price is not derivable because endpoints cost from 10 credits (panchang) to 800 (Western charts), 2,000 for calendar and batch calls and 20,000 for raja-yoga, and non-English responses cost double
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.Yes, OpenAPI 3.0 at api.prokerala.com/spec/astrology.v2.yaml
Try it without payingYes. 500 calls a month, no card, does not expire.5,000 credits a month, 5 requests a minute, no card (the FAQ says 2,500 credits)

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 Prokerala Astrology API if

  • Your users need Vedic output in Hindi, Tamil, Telugu, Malayalam, Kannada, Bengali, Marathi, Gujarati or Punjabi.
  • You need batch matchmaking, PDF reports or a WordPress plugin.
  • Your usage is dominated by the cheapest endpoints, where Prokerala's credit pricing works in your favour.

Choose Asterwise if

  • You want a bill you can forecast: a call is a call, at $1.00, $0.60 or $0.33 per thousand depending on tier.
  • You need Yogini, Ashtottari or Char dasha, or Vimshottari deeper than three levels; Prokerala's OpenAPI document offers Vimshottari to Pratyantar only.
  • You need Rajju and Vedha as vetoes on the main Ashtakoot result rather than inside the Kerala Porutham response.
  • You want an official MCP server on the registry; Prokerala has none, only a personal third-party wrapper.
  • You want to verify accuracy before you commit: Asterwise publishes its ephemeris basis and a NASA JPL Horizons check; Prokerala publishes neither.

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.
