RoxyAPI vs Prokerala: Astrology API Comparison 2026

Choosing between RoxyAPI and Prokerala comes down to four questions: how each one prices API calls, how many spiritual domains you need, whether you are building for AI agents, and which specialized features matter to your audience. Prokerala is an established Kerala-based astrology API that has served Indian astrology content for well over a decade, with deep Vedic and regional-language coverage. RoxyAPI is a newer multi-domain platform that bundles 12 insight domains behind one key with flat pricing and Remote MCP. Both serve production traffic. They are built for different product visions. This comparison lays out live-verified 2026 facts so you can pick the right one, including the honest cases where Prokerala is the better choice.

How does each provider price API calls

The pricing models are structurally different. Prokerala sells a monthly pool of credits, and each endpoint deducts a different amount. RoxyAPI sells a monthly pool of requests, and every endpoint costs exactly one request. Verified on api.prokerala.com on June 11, 2026, the Prokerala paid tiers are Ruby at 999 rupees for 100,000 credits, Emerald at 2,499 rupees for 350,000 credits, and Sapphire at 4,999 rupees for 1,000,000 credits, with a forever-free 5,000-credit tier. Unused credits do not carry forward, and extra credits cost 2,500 rupees per 100,000 with three-month validity.

Because credit cost varies by endpoint, the effective cost per call depends entirely on which endpoints your app uses. Here are live-verified Prokerala credit costs converted to the effective cost per call at the Ruby base rate (0.00999 rupees per credit, roughly 0.000105 dollars per credit at an exchange rate near 95 rupees to the dollar):

RoxyAPI charges the same regardless of endpoint complexity. Across its four plans the flat per-request cost runs from about 0.00156 dollars on the 39-dollar Starter plan (25,000 requests) down to about 0.000233 dollars on the 699-dollar Enterprise plan (3,000,000 requests). A full natal chart and a single moon-phase lookup cost the same one request.

A worked cost scenario

Consider a kundli app where each session pulls an advanced Kundli (300 credits), Dasha Periods (200), Yoga Details (200), and an advanced Mangal Dosha (100), totaling 800 credits per session. At 10,000 sessions per month that is 8,000,000 credits. Even at the cheapest published Sapphire per-credit rate, that lands near 421 dollars per month, and at the add-on rate it approaches 2,105 dollars per month. A comparable RoxyAPI build calling roughly four endpoints per session is about 40,000 requests, which fits the 149-dollar Professional plan flat. The credit model rewards light, cheap endpoints and penalizes compound, feature-rich sessions.

Which spiritual domains does each provider cover

This is the largest practical difference. Prokerala is an astrology specialist with genuine depth in the Indian tradition. RoxyAPI is a multi-domain platform that treats astrology as one of twelve domains behind a single key.

Verified live on June 11, 2026, Prokerala covers Vedic astrology, Western astrology, numerology (Pythagorean and Chaldean), daily panchang, KP astrology, marriage matching, ten traditional Indian calendar systems, and PDF reports. It does not offer tarot, dream interpretation, I-Ching, crystals, angel numbers, or biorhythm.

RoxyAPI publishes 12 genuinely distinct domains: Western Astrology, Vedic Astrology, Numerology, Tarot Reading, Human Design, Forecast, Biorhythm, I-Ching Oracle, Crystals and Healing Stones, Dream Interpretation, Angel Numbers, and Location and Timezone, spanning more than 145 endpoints under one subscription. The practical impact: if your roadmap pairs horoscopes with tarot pulls or dream journaling, RoxyAPI is one integration and one bill, whereas Prokerala would require sourcing those domains from a second provider. For Vedic depth in regional languages and Indian calendars, the balance tips the other way, as covered below.

How do RoxyAPI and Prokerala handle AI agents and SDKs

RoxyAPI is built AI-native. It publishes a Remote MCP server for every one of its 12 domains over Streamable HTTP, so agents in Claude, Cursor, VS Code, or ChatGPT can discover and call endpoints as tools with no local install and no Docker. It ships typed SDKs for TypeScript, Python, and PHP, an llms.txt discovery surface, an AGENTS.md playbook for coding agents, and free MIT-licensed starter templates you can clone and white-label. As of June 11, 2026, Prokerala publishes no Remote MCP server and no llms.txt surface, and integrates through a conventional REST API with official client libraries.

RoxyAPI also publishes its accuracy work: calculations run on the in-house Roxy Ephemeris engine, verified against NASA JPL Horizons with 3,805 automated tests including 828 gold-standard checks, plus a public MIT-licensed benchmark of 210 planet positions across 21 charts (median 16 arcsec, max 32 arcsec). If you are grounding an LLM on verified data through MCP, see the MCP documentation. If you only need server-to-server REST calls and no agent tooling, that gap will not affect you.

How to fetch a Vedic birth chart with RoxyAPI

Every coordinate-dependent endpoint starts with a location lookup so users never type latitude or longitude. Call the location search first, then feed the coordinates and timezone into the birth-chart endpoint. The fields below are verified against the live OpenAPI spec.

# 1. Resolve the city to coordinates and timezone
curl -H "X-API-Key: your_key" \
  "https://roxyapi.com/api/v2/location/search?q=Mumbai"

# 2. Generate the Vedic birth chart (kundli)
curl -X POST "https://roxyapi.com/api/v2/vedic-astrology/birth-chart" \
  -H "X-API-Key: your_key" \
  -H "Content-Type: application/json" \
  -d '{
    "date": "1990-07-04",
    "time": "10:12:00",
    "latitude": 28.6139,
    "longitude": 77.209,
    "timezone": "Asia/Kolkata"
  }'

The timezone field accepts either an IANA string like Asia/Kolkata or a decimal offset like 5.5, and time uses HH:MM:SS. Full request and response schemas are in the Vedic birth chart reference. Accuracy methodology is documented on the methodology page.

When to choose Prokerala

Prokerala is the better pick for several honest cases, all verified live on June 11, 2026:

• You only need astrology, numerology, or panchang and nothing else. A single-domain Vedic or Western app does not benefit from RoxyAPI breadth, and the Prokerala free tier lets you prototype before spending anything.
• You need regional Indian language output. Prokerala returns many endpoints in Hindi, Tamil, Malayalam, and Telugu at the calculation layer.
• You need traditional Indian calendars. Prokerala offers Tamil, Malayalam, Shaka Samvat, Vikram Samvat, Amanta, Purnimanta, Hijri, Gujarati, Bengali, and Lunar calendar feeds.
• You need ready-made PDF reports. Prokerala generates white-label Vedic and Western PDF reports, which RoxyAPI does not offer.
• You run deep matrimonial matching. Prokerala supports batch compatibility against up to 500 profiles in one request, plus Kerala Porutham and Tamil Porutham systems.
• Your usage is light and cheap. If your app mostly calls low-credit endpoints like basic panchang at 10 credits, the credit wallet can be very inexpensive.

When to choose RoxyAPI

RoxyAPI fits a different set of needs:

• You need more than astrology. Tarot, dreams, I-Ching, crystals, angel numbers, and biorhythm are included on every plan, alongside Western and Vedic astrology and numerology.
• You want predictable billing. Every call is one request, so a feature-rich session costs the same per call as a simple lookup, with no credit math and no mid-month depletion.
• You are building AI agents. Remote MCP across all 12 domains, typed SDKs, llms.txt, and clone-and-ship templates remove the custom wrapper work.
• You serve mixed astrological traditions. Both Western tropical and Vedic sidereal with KP support live under one key.
• You want clean licensing. The calculation engine is in-house with no AGPL or copyleft exposure, verified against NASA JPL Horizons.

FAQ

What is the difference between RoxyAPI and Prokerala pricing? Prokerala uses a credit wallet where each endpoint costs a different number of credits, so the effective cost per call depends on your endpoint mix. RoxyAPI uses flat plans where every call is one request regardless of complexity. For apps that lean on compound endpoints like advanced kundli or Western transit charts, the flat model is easier to forecast.

Is Prokerala cheaper than RoxyAPI? For very low volume or cheap endpoints, the Prokerala forever-free 5,000-credit tier and 999-rupee Ruby plan can be cheaper. Once an app uses heavier endpoints across many sessions, credits deplete quickly and add-on packs at 2,500 rupees per 100,000 credits add up. RoxyAPI flat plans become more predictable and often cheaper at scale.

Does Prokerala offer tarot, dreams, or I-Ching APIs? No. Verified on June 11, 2026, Prokerala covers Vedic astrology, Western astrology, numerology, panchang, KP, and Indian calendars. For tarot, dream interpretation, I-Ching, crystals, or angel numbers you would need a separate provider, or RoxyAPI which includes all of them under one key.

Which is better for building an AI chatbot or agent? RoxyAPI is built for this. It ships a Remote MCP server for all 12 domains, typed SDKs, and an llms.txt surface, so agents discover and call endpoints with no custom wrappers. Prokerala publishes no MCP server, so AI integration requires writing and maintaining tool definitions yourself.

Is RoxyAPI a good Prokerala alternative for Vedic astrology? For multi-domain or AI-native builds, yes. RoxyAPI covers kundli, dasha, KP sub-lords, doshas, navamsa, and Guna Milan matching with flat pricing. For deep regional Indian features such as Tamil and Malayalam calendars, regional-language output, batch matrimonial matching, and PDF reports, Prokerala remains the more specialized choice.

Conclusion

Prokerala and RoxyAPI both calculate astrology accurately, but they target different builders. Prokerala suits single-domain Indian astrology apps that need regional languages, traditional calendars, or PDF reports on a credit wallet. RoxyAPI suits multi-domain and AI-native apps that want flat pricing and Remote MCP across 12 domains. Compare the Vedic Astrology API and check current pricing to see which model fits your roadmap.
