RoxyAPI vs Prokerala API: Complete Astrology API Comparison for 2026
Detailed comparison of RoxyAPI and Prokerala astrology APIs. Features, pricing, domains, AI readiness, and documentation compared side by side.
RoxyAPI vs Prokerala API: Complete Astrology API Comparison for 2026
Prokerala is one of the most established names in astrology APIs. Operating since 2006, it has served as a reference standard for Vedic astrology calculations for nearly two decades. If you have ever evaluated astrology APIs, Prokerala was probably on your list.
RoxyAPI is a newer entrant that takes a fundamentally different approach: instead of focusing on one domain, it bundles six spiritual domains under a single API key and builds AI-native from the ground up.
Both are serious options. But they serve different needs and different product visions. This comparison lays out the facts so you can choose the right one for your project.

Domain Coverage: The Biggest Difference
This is where the two providers diverge most significantly.
Prokerala focuses on astrology. It does astrology very well. Vedic kundli generation, dasha calculations, panchang, matchmaking, and Western birth charts are all covered. If your app only needs astrology and nothing else, Prokerala is a capable choice.
RoxyAPI covers six domains: Western astrology, Vedic astrology, tarot, numerology, I-Ching, and dream interpretation. Every plan includes every domain. There is no per-domain pricing.
Why this matters in practice:
The highest-grossing spiritual apps in 2026 combine multiple modalities. Users who check their horoscope also pull tarot cards. Users who calculate their birth chart also want their life path number. Apps that offer this variety have higher engagement, longer sessions, and better retention.
With Prokerala, adding tarot means finding and integrating a second API provider. Adding numerology means a third. Adding I-Ching and dreams? Good luck finding providers at all.
With RoxyAPI, all six domains are one integration, one API key, one bill.
Vedic Astrology: Head to Head
Both providers offer strong Vedic astrology coverage. Here is the detailed comparison:
| Vedic Feature | RoxyAPI | Prokerala |
|---|---|---|
| Kundli generation | Yes | Yes |
| Nakshatras (27) | Yes | Yes |
| Vimshottari Dasha | Yes | Yes |
| Dasha sub-periods | Yes | Yes |
| Panchang | Yes | Yes |
| Ashtakoota matching | Yes | Yes |
| Manglik Dosha | Yes | Yes |
| Kaal Sarp Dosha | Yes | Yes |
| Sade Sati | Yes | Yes |
| Divisional charts | Yes | Yes |
| KP System | Yes | Partial |
| Multiple Ayanamsas | Yes | Lahiri primarily |
| Yoga detection | Yes | Yes |
The Vedic coverage is comparable. Prokerala has the advantage of a longer track record and is widely used as an accuracy reference. RoxyAPI adds KP system support and multiple ayanamsa options, which matter for developers serving different astrological traditions.
Western Astrology: Head to Head
| Western Feature | RoxyAPI | Prokerala |
|---|---|---|
| Birth chart | Yes | Yes |
| Planetary positions | Yes | Yes |
| House systems | Multiple | Multiple |
| Aspects | Yes | Yes |
| Zodiac signs | Yes | Yes |
| Tropical zodiac | Yes | Yes |
| Sidereal zodiac | Yes | Yes |
| Transits | Yes | Yes |
Both providers cover Western astrology fundamentals. No significant gaps on either side for core chart calculations.
AI and Agent Readiness
This is where the difference is stark.
RoxyAPI:
- Ships with an MCP server for AI agent integration
- Provides llms.txt for AI discoverability
- OpenAPI documentation with Scalar (interactive, detailed field descriptions)
- Every response field has descriptions written for both humans and AI agents
- Structured JSON designed for tool-call consumption
Prokerala:
- Standard REST API
- No MCP server
- No llms.txt
- Basic API reference documentation
- Not designed for AI agent consumption
In 2026, this matters. The agentic AI market is projected to reach $52 billion by 2030. 40% of enterprise apps will embed AI agents by year end. If you are building anything with AI, chatbots, agents, LLM-powered features, MCP support and AI-optimized documentation are not nice-to-haves. They are requirements.
Documentation Quality
Prokerala provides functional API documentation with endpoint descriptions, parameter lists, and response examples. It gets the job done. Developers can integrate without major issues.
RoxyAPI uses Scalar-powered OpenAPI documentation with interactive API exploration, detailed field descriptions that explain what each value means and how to use it, and examples throughout. The documentation is explicitly designed for two readers: human developers and AI agents.
For developers who want to integrate quickly, the documentation quality difference translates to faster onboarding and fewer support requests.
Pricing Comparison
Prokerala Pricing
- Free tier: 50 queries/month
- Paid plans: approximately $0.05-0.15 per call (varies by plan)
- Covers astrology only (Vedic + Western)
RoxyAPI Pricing
- Starter: $39/month (5,000 requests, all 6 domains)
- Professional: $149/month (50,000 requests, all 6 domains)
- Business: $349/month (200,000 requests, all 6 domains)
- Enterprise: $699/month (1,000,000 requests, all 6 domains)
Cost Scenarios
Scenario 1: Astrology-only app, 5,000 requests/month
| Provider | Monthly Cost |
|---|---|
| Prokerala | $250-750 (at $0.05-0.15/call) |
| RoxyAPI | $39 (Starter plan) |
Scenario 2: Astrology + Tarot + Numerology app, 10,000 requests/month
| Provider | Monthly Cost |
|---|---|
| Prokerala + separate tarot + separate numerology | $500-1,500+ (3 providers) |
| RoxyAPI | $39-149 (one plan, all included) |
Scenario 3: High-volume astrology app, 50,000 requests/month
| Provider | Monthly Cost |
|---|---|
| Prokerala | $2,500-7,500 (at $0.05-0.15/call) |
| RoxyAPI | $149 (Professional plan) |
The pricing advantage shifts heavily toward RoxyAPI at scale, and even more so when multiple domains are involved.
The Free Tier Question
Prokerala offers 50 free queries per month. RoxyAPI does not have a free tier. For prototyping and testing, this gives Prokerala an advantage. You can validate your concept without spending anything.
However, 50 queries is extremely limited for any real testing. A single user session might generate 3-5 API calls. That gives you 10-15 test sessions before you need to pay anyway.
When to Choose Prokerala
Choose Prokerala when:
- You only need astrology (Vedic and/or Western) and nothing else
- You want a free tier to prototype before committing any budget
- You value a long track record and established reputation
- Your app serves a Vedic astrology audience exclusively
- You do not need AI agent features, MCP, or llms.txt
- Your request volume is very low (under 50/month for the free tier)
Prokerala is a solid, mature astrology API. It has earned its reputation over nearly two decades. If astrology is all you need and you do not care about AI-native features, it remains a viable choice.
When to Choose RoxyAPI
Choose RoxyAPI when:
- You need multiple spiritual domains (astrology + tarot + numerology + more)
- You are building AI agents, chatbots, or LLM-powered features
- You want MCP server support and AI-discoverable documentation
- You need both Vedic and Western astrology with multiple ayanamsa options
- You want KP system support
- You want one API key, one integration, one bill for everything
- Your request volume makes subscription pricing more economical than per-call
- You value premium documentation with interactive exploration
RoxyAPI is designed for builders who want to ship fast, cover multiple domains, and stay ready for the AI-native future.
Migration Considerations
If you are currently using Prokerala and considering switching:
What transfers easily: Both APIs accept similar inputs (birth date, time, latitude, longitude, timezone). Response data covers the same astrological concepts. The core integration pattern is the same: send birth details, receive chart data.
What changes: Endpoint paths and response structure differ. Field names will be different. You will need to update your API client code. Plan for 1-2 weeks of migration work depending on how deeply integrated your current solution is.
What you gain: Additional domains (tarot, numerology, I-Ching, dreams) without new integrations, MCP server for AI features, and potentially significant cost savings at scale.
The Bottom Line
Prokerala and RoxyAPI solve the same core problem (astrology calculations for apps) but target different product visions:
- Prokerala is for apps that need astrology and only astrology, built with traditional REST integration.
- RoxyAPI is for apps that need a complete spiritual intelligence layer, built for the AI-native era.
The market is moving toward multi-domain, AI-native products. The top-grossing spiritual apps combine multiple modalities. AI agents need structured, discoverable APIs. If your product roadmap points in this direction, choosing RoxyAPI now saves you from a migration later.
Frequently Asked Questions
Q: Is RoxyAPI as accurate as Prokerala for Vedic astrology? A: Both providers use high-precision ephemeris engines for planetary calculations. RoxyAPI has been validated against Prokerala outputs through end-to-end testing. For core calculations (planetary positions, nakshatras, dashas), accuracy is comparable. Always verify against reference charts for your specific use case.
Q: Does Prokerala offer tarot or numerology? A: No. Prokerala focuses exclusively on astrology (Vedic and Western). For tarot, numerology, I-Ching, or dream interpretation, you would need additional providers.
Q: Can I use both providers together? A: Yes. Some developers use Prokerala for specific Vedic calculations and RoxyAPI for additional domains (tarot, numerology) or AI features. However, managing two providers adds complexity. Most teams prefer consolidating to one.
Q: Which provider has better uptime? A: Prokerala has a two-decade track record. RoxyAPI provides production-grade infrastructure. Both serve production traffic reliably. Check each provider's status page for current uptime metrics.
Q: Is Prokerala cheaper for low-volume usage? A: Prokerala offers 50 free queries/month, which is cheaper than any paid plan for extremely low volumes. However, once you exceed the free tier, RoxyAPI's subscription model ($39/month for 5,000 requests across all domains) is typically more economical than Prokerala's per-call pricing.
Q: Which is better for building an AI chatbot? A: RoxyAPI, definitively. It ships with an MCP server for AI agent integration, llms.txt for discoverability, and documentation designed for AI consumption. Prokerala does not offer AI-native features. Building an AI chatbot with Prokerala requires significantly more custom integration work.
