Best Astrology APIs for Developers in 2026: Complete Comparison Guide

Choosing the right astrology API can make or break your product. Pick the wrong one and you are stitching together three different providers, paying triple, and still missing tarot and numerology. Pick the right one and you ship a full-featured spiritual app in a weekend.

The astrology API market has exploded. There are now over 15 providers, each with different strengths, pricing models, and domain coverage. Some only do Vedic astrology. Some only do horoscopes. Some are adding AI features. And one covers six spiritual domains under a single API key.

This guide compares the top astrology APIs available to developers in 2026, based on real features, real pricing, and real technical capabilities. No hype, just data.

What to Look for in an Astrology API

Before diving into specific providers, here is what actually matters when choosing an astrology API for production use:

• Domain coverage: Does it cover just astrology, or also tarot, numerology, dreams, I-Ching? Building a spiritual app with one provider is far simpler than juggling three.
• Vedic and Western support: Many apps need both systems. Some APIs only support one.
• Accuracy: Planetary position calculations must be precise. Look for Swiss Ephemeris or equivalent precision.
• AI and MCP readiness: If you are building AI agents or chatbots, you need structured JSON responses, MCP server support, and AI-discoverable documentation.
• Documentation quality: Can an AI agent read your docs? Can a developer integrate in under an hour?
• Pricing model: Per-request vs subscription vs per-domain pricing changes your unit economics dramatically.

Vedic Rishi

Best for: Indian astrology app developers building kundli-based products on a budget.

Popular among Indian developers for its affordable pricing and Vedic-specific features including panchang, nakshatra, dasha, and matchmaking tools. Supports Hindi and regional languages.

Pricing: Affordable tiered plans, generally lower cost than competitors.

Strengths: Budget-friendly, regional language support, strong Vedic focus. Limitations: Vedic only, no Western astrology, no other spiritual domains. Basic documentation.

Vedika.io

Best for: Teams building conversational AI chatbots that need natural language astrology queries.

Vedika is the newest entrant, positioning as the first "AI-native" astrology API. It accepts natural language questions like "When will I get married?" and returns synthesized astrological analysis. Supports 30 languages.

Pricing: $0.25-0.87 per call depending on volume and complexity. No free tier (sandbox with mock data only).

Strengths: Conversational AI interface, multi-language support, natural language queries. Limitations: Vedic astrology only. Expensive per-call pricing. No tarot, numerology, I-Ching, or dreams. Higher latency (1-3 seconds for AI synthesis).

Pricing Comparison: What Does Full Coverage Actually Cost?

Here is the real question most developers face: what does it cost to cover the domains your app needs?

Scenario	RoxyAPI	Multiple Providers
Astrology only (5,000 calls/mo)	$39/mo	$29-79/mo (one provider)
Astrology + Tarot + Numerology	$39/mo (included)	$87-237/mo (2-3 providers)
All 6 spiritual domains	$39/mo (included)	Not possible (no single alternative covers all)
50,000 calls across all domains	$149/mo	$447-750/mo estimated (multiple providers)

The math is clear. If you need more than just astrology, a multi-domain provider saves significant cost and integration complexity.

AI Agent and MCP Readiness

This is the fastest-growing consideration for API selection in 2026. Gartner predicts 40% of enterprise applications will embed AI agents by the end of this year. If you are building any kind of AI-powered product, your API choice must support agent workflows.

What AI-ready means in practice:

• MCP server: Your AI agent can discover and call the API through the Model Context Protocol standard
• llms.txt: AI systems can read your documentation and understand your capabilities automatically
• Structured JSON: Predictable, well-documented response schemas that agents can parse reliably
• OpenAPI with descriptions: Every field documented so agents know what data they are working with

Currently, RoxyAPI is the only astrology API provider offering MCP server support and llms.txt. Vedika offers partial AI readiness through their conversational interface, but it is designed for end-user queries rather than agent-to-API tool calls.

When to Choose Each Provider

Choose RoxyAPI when:

• You need multiple spiritual domains (astrology + tarot + numerology + more)
• You are building AI agents or chatbots that need structured spiritual data
• You want one API key, one integration, one bill
• You need both Vedic and Western astrology
• You want MCP-native architecture

Choose Prokerala when:

• You only need Vedic astrology
• You want a free tier to prototype
• You need an established provider with a long track record
• Budget is extremely tight and you only need basic astrology

Choose AstrologyAPI.com when:

• You need the largest number of Vedic astrology endpoints
• You want pre-built SDKs in your language
• Matchmaking is a core feature of your app

Choose Vedika when:

• You are building a conversational chatbot specifically for Vedic astrology
• You need natural language query support built into the API
• Multi-language support (30 languages) is critical

Choose Vedic Rishi when:

• You are building for the Indian market specifically
• Regional language support matters
• You need the lowest possible per-call cost for Vedic features

The Multi-Domain Advantage

Here is what most comparison guides miss: the real cost of using multiple single-domain APIs is not just the subscription fees. It is the engineering time.

Every additional provider means:

• Another authentication system to manage
• Another set of documentation to learn
• Another error handling pattern to implement
• Another billing relationship to track
• Another point of failure in your production stack

If your app combines astrology readings with tarot pulls and numerology calculations (which is exactly what the top-grossing spiritual apps do), a single multi-domain API eliminates weeks of integration work.

For Developers: Getting Started

Ready to start building? Here is the fastest path to a working astrology integration:

1. Get an API key from your chosen provider
2. Read the API documentation and identify the endpoints you need
3. Start with birth chart generation as your first integration (it is the foundation for most astrology features)
4. Add domain-specific features like tarot, numerology, or daily horoscopes based on your product requirements

RoxyAPI provides comprehensive documentation with code examples for every endpoint. Check our API docs to see the full capability set.

Frequently Asked Questions

Q: What is the most accurate astrology API in 2026? A: Accuracy depends on the underlying ephemeris engine. Providers using Swiss Ephemeris (which provides NASA JPL-grade precision) deliver the most accurate planetary calculations. RoxyAPI, Prokerala, and AstrologyAPI.com all use high-precision calculation engines. Always verify accuracy by comparing output against established reference points.

Q: Which astrology API supports both Vedic and Western astrology? A: RoxyAPI and Prokerala both support Vedic and Western astrology systems. Most other providers focus exclusively on one system. If your app needs to serve users who follow different astrological traditions, choose a provider that covers both.

Q: Is there an astrology API with tarot and numerology included? A: RoxyAPI is currently the only API provider that bundles astrology (both Vedic and Western), tarot, numerology, I-Ching, and dream interpretation under a single API key. All other providers require you to use separate services for non-astrology domains.

Q: What does MCP support mean for an astrology API? A: MCP (Model Context Protocol) is the emerging standard for connecting AI agents to external tools and data sources. An astrology API with MCP support means AI agents (built with Claude, GPT, or other LLMs) can discover and call your astrology endpoints automatically, without custom integration code. This is increasingly important as AI-powered apps become the norm.

Q: How much does an astrology API cost for a startup? A: Costs vary widely. Free tiers exist (Prokerala offers 50 calls/month). Paid plans range from $29/month for basic astrology to $39/month for multi-domain coverage (RoxyAPI) to $0.25-0.87 per call for AI-native providers (Vedika). For startups, the key consideration is total cost across all domains you need, not just the per-call price for one domain.

Q: Can I use an astrology API to build a dating app? A: Yes. Compatibility and synastry (relationship chart comparison) endpoints are specifically designed for this use case. Look for APIs that offer birth chart comparison, aspect analysis between two charts, and compatibility scoring. The astrology dating app market is one of the fastest-growing segments in 2026.

Q: Which astrology API is best for AI chatbots? A: It depends on your architecture. If you want the API to handle natural language processing, Vedika is designed for conversational queries. If you want structured data that your own AI layer interprets (giving you more control), RoxyAPI provides well-documented JSON responses with MCP server support, letting your AI agent call specific endpoints as tools.
