Best Astrology APIs for Developers in 2026: Pricing, Features, and AI Integration Compared
Compare the top astrology APIs for developers in 2026. Side-by-side pricing, feature tables, AI agent readiness, and honest recommendations for every use case.
Best Astrology APIs for Developers in 2026: Pricing, Features, and AI Integration Compared
The astrology API market has grown significantly since 2024. More providers, more endpoints, more pricing models. For developers evaluating which API to build on, the choices can feel overwhelming. Some providers charge per credit, others per product, others per query, and a few charge a flat rate per request.
This guide compares seven major astrology API providers based on what actually matters for production applications: pricing predictability, feature coverage, documentation quality, AI agent integration, and long-term scalability.
Every claim in this comparison is based on publicly available pricing pages and documentation reviewed in February 2026. Pricing and features change, so verify directly with each provider before committing.
Quick Comparison: All Providers at a Glance
| Provider | Pricing Model | Starting Price | Domains Covered | AI Agent Support | Flat Pricing |
|---|---|---|---|---|---|
| RoxyAPI | Flat per-request | $39/mo (5K requests) | 6 (Western, Vedic, Tarot, Numerology, Dreams, I-Ching) | Native MCP | Yes |
| Prokerala | Credit-based | Free (5K credits) | 4 (Vedic, Western, Numerology, Panchang) | No | No |
| DivineAPI | Per-product subscription | ~$18/mo per product | 5 (Western, Vedic, Tarot, Numerology, Horoscope) | No | No |
| Astrology-API.io | Credit-based (premium tiers) | Free (50/mo) | 3+ (Western, Vedic, Tarot/Numerology at higher tiers) | No | Partial |
| AstrologyAPI.com | Per-domain subscription | Varies by domain | 4 (Vedic, Western, Horoscope, PDF) | No | No |
| Vedika.io | Per-query AI pricing | $0.15/query | 2 (Vedic, Western) | Built-in AI chat | No |
| FreeAstroAPI | Flat per-request | Free (80/day) | 3 (Western, Vedic, Chinese BaZi) | No | Yes |
Pricing Models: What You Actually Pay
The biggest source of confusion when comparing astrology APIs is pricing. Four different models exist in the market, and each has trade-offs.
1. Flat Per-Request Pricing
Every API call costs the same, regardless of endpoint complexity. A simple planet position call and a full birth chart with aspects, houses, and interpretations both count as one request.
Who uses this: RoxyAPI, FreeAstroAPI
Advantage: Fully predictable costs. You know exactly what your monthly bill will be.
Trade-off: Higher base price than free tiers or credit-based starters.
2. Credit-Based Pricing
You buy a pool of credits each month. Different endpoints consume different numbers of credits. A basic Panchang call might cost 10 credits while a Western natal chart costs 500 credits and a PDF report costs 350,000 credits.
Who uses this: Prokerala, Astrology-API.io (at Ultra+ tier)
Advantage: Low entry price. Prokerala offers a free plan with 5,000 credits.
Trade-off: Unpredictable costs. You cannot calculate your monthly spend without knowing exactly which endpoints your users will hit. Credit costs vary 35,000x between cheapest and most expensive endpoints on Prokerala (10 credits for basic Panchang vs 350,000 for a Saturn transit PDF).
3. Per-Product Subscription
Each domain or feature set requires a separate subscription. Want horoscopes? One subscription. Want Western astrology? Another subscription. Want Vedic Kundali? A third subscription.
Who uses this: DivineAPI, AstrologyAPI.com
Advantage: Pay only for what you use. If you only need horoscopes, you pay for horoscopes.
Trade-off: Costs stack fast for multi-domain apps. A developer who needs Western astrology + Vedic astrology + tarot + numerology on DivineAPI could pay four separate subscriptions totaling over $500/month for mid-tier plans.
4. Per-Query AI Pricing
Each query is priced based on AI model compute. Simple queries cost less, complex multi-chart queries cost more.
Who uses this: Vedika.io
Advantage: Pay-as-you-go with no monthly commitment.
Trade-off: Unpredictable costs at scale. A complex query costs $0.45, meaning 10,000 complex queries per month = $4,500. Response times are also slower (28-36 seconds per AI query) since every request goes through an LLM.
Pricing Comparison: Real Monthly Costs
Here is what each provider actually costs for common usage scenarios.
Scenario: Small App (5,000 requests/month)
| Provider | Plan Needed | Monthly Cost | Notes |
|---|---|---|---|
| RoxyAPI | Starter | $39 | All 6 domains included |
| Prokerala | Ruby (₹999) | ~$12 | 100K credits, but cost depends on which endpoints are called |
| DivineAPI | Natal Nova | ~$53 | Western only. Add ~$18 for Vedic Panchang, ~$18 for Kundali |
| Astrology-API.io | Pro Plus | $21 | 7K requests, standard endpoints only |
| AstrologyAPI.com | Varies | $50-150+ | Depends on which domains you subscribe to |
| Vedika.io | Pay-as-you-go | $750-2,250 | At $0.15-$0.45 per AI query |
| FreeAstroAPI | Entry | $8 | 50K requests, Western + Vedic + BaZi only |
Scenario: Production App (50,000 requests/month)
| Provider | Plan Needed | Monthly Cost | Notes |
|---|---|---|---|
| RoxyAPI | Professional | $149 | All 6 domains included |
| Prokerala | Sapphire (₹4,999) | ~$60 | 1M credits, but complex endpoints drain fast |
| DivineAPI | Natal Atlas | ~$107+ | Western only at this tier. Multi-domain = $300+ |
| Astrology-API.io | Business | $99 | 220K credits, but premium endpoints cost 2-100 credits each |
| AstrologyAPI.com | Custom | Contact sales | No public pricing for this volume |
| Vedika.io | Pay-as-you-go | $7,500-22,500 | Not viable for high-volume production |
| FreeAstroAPI | High | $40 | 500K requests, but limited domains |
Key Takeaway
For multi-domain apps (astrology + tarot + numerology + more), RoxyAPI is the only provider where a single subscription covers everything. With DivineAPI and AstrologyAPI.com, you need separate subscriptions per domain. With Prokerala, your credit pool gets consumed faster by complex endpoints. With Vedika.io, per-query AI pricing becomes prohibitively expensive at scale.
For single-domain apps on a tight budget, FreeAstroAPI ($8/mo for 50K requests in Western + Vedic) and Prokerala (free tier for basic Vedic) offer lower entry points.

AI Agent Integration: MCP and Beyond
If you are building AI-powered products (chatbots, copilots, AI agents), the integration method matters significantly.
| Provider | MCP Support | OpenAPI Spec | AI-Friendly Docs | Agent Discovery |
|---|---|---|---|---|
| RoxyAPI | Native MCP | Yes (OpenAPI 3.1) | llms.txt + llms-full.txt | ai-plugin.json |
| Prokerala | No | No public spec | Standard docs | No |
| DivineAPI | No | No public spec | Standard docs | No |
| Astrology-API.io | No | Claimed | Standard docs | No |
| AstrologyAPI.com | No | No public spec | Standard docs, Postman | No |
| Vedika.io | No | No public spec | Standard docs | No |
| FreeAstroAPI | No | No public spec | Standard docs | No |
What This Means
MCP (Model Context Protocol) is the open standard developed by Anthropic that lets AI agents auto-discover and call API endpoints as tools. With MCP support, an OpenAI Agent, Claude Desktop, Gemini Agent, Cursor, or Windsurf can connect to an API and immediately use all its endpoints without custom integration code.
RoxyAPI is the only astrology API provider with native MCP support. This means AI agents can discover all 85+ endpoints across 6 domains as callable tools with zero configuration.
Other providers require developers to manually write tool definitions, parse responses, handle authentication, and maintain wrapper code for every endpoint they want an AI agent to use. This adds weeks of development time and ongoing maintenance.
If your product involves AI agents in any capacity, MCP support is a significant technical advantage.
Documentation Quality
Good documentation reduces integration time. Great documentation makes an API self-serve.
| Provider | Interactive Docs | Code Examples | SDK/Client Libraries | Testing Interface |
|---|---|---|---|---|
| RoxyAPI | Scalar (interactive, themed) | Yes (curl, multi-language) | OpenAPI spec for code generation | Live testing in docs |
| Prokerala | Standard | PHP, C#, Python, Ruby clients | Sample API clients | Limited |
| DivineAPI | Standard | Limited | No official SDK | Preview widgets |
| Astrology-API.io | Standard | JavaScript examples | Claimed SDKs | API playground |
| AstrologyAPI.com | Standard | Yes | Postman collection | Via Postman |
| Vedika.io | Standard | cURL examples | No SDK | API playground |
| FreeAstroAPI | Standard | cURL examples | No SDK | API playground |
RoxyAPI also provides /llms.txt and /llms-full.txt endpoints that deliver AI-friendly documentation for coding assistants like Cursor, Windsurf, and GitHub Copilot. These structured documentation endpoints help AI tools generate more accurate integration code.

What to Watch For
A few patterns show up across astrology API providers that developers should be aware of:
Credit-based pricing can be misleading. A plan that advertises "100,000 credits" sounds generous until you realize a single complex endpoint can cost 500 credits. Always calculate your expected credit consumption based on your specific endpoint mix before committing.
Per-product pricing stacks. If you need three domains, you pay three subscriptions. Always calculate total cost for all domains you will use, not just the starting price for one.
Free tiers have limits beyond requests. Some free tiers limit rate to 5 requests/minute, restrict to basic endpoints only, or exclude commercial use. Read the terms.
AI interpretations add latency. Providers like Vedika.io that run every query through an LLM have response times of 28-36 seconds. If your app needs sub-second responses, raw calculation APIs are faster than AI-interpreted ones.
Endpoint counts can be inflated. A provider claiming "300+ endpoints" might count each parameter variation as a separate endpoint. Focus on unique functionality, not raw endpoint counts.
For Developers: Building with Astrology APIs
When evaluating astrology APIs for production use, consider these technical factors:
Response format consistency. The best APIs return clean JSON with consistent field naming across all endpoints. Avoid APIs that return different response structures for similar operations.
Authentication simplicity. API key authentication (header or query parameter) is the simplest to implement and maintain. Avoid providers that require OAuth flows or token refresh logic for server-to-server API calls.
Rate limit transparency. Production APIs should include rate limit headers (X-RateLimit-Limit, X-RateLimit-Remaining) in every response so your application can handle limits gracefully.
OpenAPI specifications. A published OpenAPI spec enables automatic client generation in any language. This saves weeks of manual SDK development. RoxyAPI provides a full OpenAPI 3.1 specification with interactive Scalar documentation.
Timezone handling. Astrology calculations are sensitive to timezone. The best APIs accept timezone offset as a parameter and handle conversion internally. Avoid APIs that require you to convert to UTC before sending.

Frequently Asked Questions
Q: What is the best astrology API for developers in 2026? A: It depends on your use case. For multi-domain apps (astrology + tarot + numerology + dreams), RoxyAPI provides the broadest coverage under one subscription. For deep Vedic specialization, Prokerala offers the most comprehensive Jyotish features. For budget-conscious prototyping, FreeAstroAPI starts at $8/month for 50K requests.
Q: Which astrology API has the most predictable pricing? A: RoxyAPI and FreeAstroAPI both use flat per-request pricing where every API call costs the same regardless of endpoint complexity. Credit-based providers like Prokerala and Astrology-API.io have variable costs per endpoint, making monthly bills harder to predict.
Q: Which astrology API supports AI agents and MCP? A: RoxyAPI is the only astrology API with native Model Context Protocol (MCP) support as of February 2026. This enables AI agents from OpenAI, Claude, and Gemini to auto-discover and call endpoints as tools without custom integration code. Other providers require manual tool definition wrappers.
Q: Can I use astrology APIs for commercial applications? A: Yes. All providers listed here allow commercial use on paid plans. Free tiers may have restrictions. Always check the terms of service for your specific use case, especially around reselling generated content and white-label requirements.
Q: Which astrology API has tarot, numerology, and dream interpretation? A: RoxyAPI is the only provider that includes tarot (10 endpoints), numerology (12 endpoints), dream interpretation (4 endpoints), and I-Ching (9 endpoints) alongside Western and Vedic astrology in every plan. Other providers either do not offer these domains or charge separately for each.
Q: How do credit-based astrology API pricing models work? A: Credit-based providers give you a pool of credits each month. Each API call deducts a different number of credits depending on the endpoint. For example, on Prokerala, a basic Panchang call costs 10 credits, a Kundali costs 50-300 credits, and a PDF report can cost up to 350,000 credits. Your actual monthly cost depends on which mix of endpoints your users call.
Q: What is the cheapest astrology API for a production app? A: For the lowest absolute cost, FreeAstroAPI offers 50,000 requests for $8/month covering Western, Vedic, and Chinese astrology. However, it does not include tarot, numerology, or dreams. For the best value across multiple domains, RoxyAPI offers 5,000 requests across 6 domains for $39/month, or 50,000 requests for $149/month.
Q: Which astrology API has the best documentation? A: RoxyAPI uses Scalar for interactive documentation with live endpoint testing, plus AI-friendly /llms.txt and /llms-full.txt endpoints for coding assistants. Prokerala provides sample API clients in four languages. AstrologyAPI.com offers a Postman collection. Most other providers offer standard reference documentation.
Q: Do astrology APIs use Swiss Ephemeris for calculations? A: Most reputable astrology APIs use Swiss Ephemeris (based on NASA JPL ephemeris data) for planetary calculations. This includes RoxyAPI, Prokerala, FreeAstroAPI, and Astrology-API.io. Swiss Ephemeris provides sub-arcsecond precision for planetary positions, which is the industry standard for professional-grade astrological software.
