More than astrology. The spiritual intelligence suite.

RoxyAPI is the spiritual intelligence suite: Astrology, Vedic, Forecast, Human Design, Numerology, Tarot, Biorhythm, I-Ching, Crystals, Dreams, Angel Numbers, and Location. 12+ genuinely distinct domains, not sub-features or output formats, under one API key and one flat plan, with a complete result in one call.

The suite is more than endpoints: per-domain Remote MCP servers, typed SDKs, drop-in UI components, free MIT licensed templates, and a WordPress plugin ship with every plan. Your AI grounds each reading in calculations verified against NASA JPL Horizons and answers in your product voice.

12+domains
one key

One call. Real data.

Every endpoint returns structured JSON with documented fields, not hallucinated text. Verified calculations you can trust in production.

  • Open MIT-licensed benchmark, validated against NASA JPL Horizons
  • Sub-50ms responses. Numerology, tarot, and dreams return instantly.
  • 166+ endpoints. Every field has descriptions and examples.
  • Editorial interpretations in 8+ languages. Ship readings without writing them, or layer on your own voice.

Honest footnote: if you need exactly one domain, run your own servers, and are comfortable with copyleft licensing, a free open source library is the cheaper choice. Everything else on this table is where RoxyAPI earns its keep.

Everything you need to build and ship.

Production APIs, hosted agent surfaces, typed SDKs, drop-in UI, embeddable widgets, and white label Templates. Every entry below links to the real thing, not a promise.

Built for AI agents

Your agent decides which domain each question needs (a transit, a tarot pull, a life path number) and calls it mid-conversation. Every domain sits behind one key and one Remote MCP surface, so 166+ tools auto-discover with zero configuration and adding a domain means no new vendor, auth, or bill.

Your AI agentyour model, your voice
Remote MCPauto-discovered, no local setupToken-optimized
Roxy Ephemeris5,114 tests, 828 vs NASA JPL
Verified result12 domains, one flat rate

Your agent grounds every answer in verified calculations and replies in your own voice, so it never hallucinates a chart, date, or reading. No local setup, no AGPL, no hosted-AI markup.

Token-optimized responses

Roxy MCP can hand your agent the same complete data in a compact, lossless shape that sends each field name once instead of once per row, cutting the tokens it spends reading a result by roughly 40 to 52 percent. Lower inference cost, and your quota is unchanged: one tool call is still one request.

Remote MCP servers

AI agents auto-discover all endpoints as callable tools. No manual tool definitions. No endpoint wiring.

Claude DesktopCursorWindsurfVS CodeOpenAI AgentsGemini

Real calculations, not AI slop

Your chatbot answers with computed planetary positions, not hallucinated readings. Every number is calculated by Roxy Ephemeris and verified against NASA JPL Horizons, with a public MIT-licensed benchmark anyone can re-run.

Frequently asked questions

What the astrology API does, how accurate it is, and how AI agents use it.

What is an astrology API?

An astrology API returns computed astrology data, natal charts, horoscopes, transits, and compatibility, over HTTP as structured JSON, so you can build features without writing the astronomy yourself. RoxyAPI is a multi-domain example: one key also covers Vedic astrology, forecast, human design, numerology, tarot, and more, with every calculation verified against NASA JPL Horizons.

Which astrology API is best for AI agents?

RoxyAPI is built for AI agents. Every domain ships a Remote MCP server over Streamable HTTP, so Claude, Cursor, VS Code, and OpenAI agents auto-discover the tools in seconds with no local setup. Your agent picks the domain each question needs (astrology, human design, forecast, numerology) and calls it mid-conversation, with every domain behind one key so adding a capability means no new vendor or bill. It also serves llms.txt and an AGENTS.md playbook, so coding agents call real endpoints instead of hallucinating them and ground each answer in verified calculations.

How accurate is RoxyAPI, and how is that verified?

Every calculation runs on Roxy Ephemeris and is verified against NASA JPL Horizons, with a public MIT licensed benchmark anyone can re-run. A gold-standard test suite cross-references each domain against authoritative sources, and the live API reference returns real production responses, so you can audit accuracy before you pay.

How is RoxyAPI different from legacy astrology APIs?

Three structural differences. Scope: legacy providers sell astrology, while RoxyAPI covers 12 spiritual intelligence domains, astrology, Vedic astrology, forecast, human design, numerology, tarot, and more, under one key and one flat plan where one request equals one quota unit with no credit weighting. Proof: accuracy is published rather than asserted, with 5,114 automated tests on every deploy, 828 of them gold-standard tests pinned to named external references, plus an open MIT benchmark anyone can re-run against NASA JPL Horizons DE441 and point at any provider. Architecture: Roxy Ephemeris is built in house for APIs and AI agents at NASA JPL Horizons parity, with a Remote MCP server per domain, llms.txt, and AGENTS.md. Legacy providers wrap Swiss Ephemeris, a 1990s desktop-era library whose AGPL reaches network services, so products built on unlicensed wrappers inherit that obligation whether they know it or not. Honest exception: if you need exactly one domain, run your own servers, and are comfortable with copyleft licensing, a free open source library is cheaper.

Can one API key access every domain?

Yes. A single RoxyAPI subscription unlocks every domain, every endpoint, and Remote MCP under one key, with no per-product locks and no variable token costs. You integrate once and get astrology, Vedic astrology, forecast, human design, numerology, tarot, and the rest from the same flat plan, with editorial interpretations available in eight languages.

What can I build with RoxyAPI?

The fastest-growing 2026 app categories all map to RoxyAPI: AI astrology companions and reading chatbots grounded in real calculations instead of hallucinated text, dating and relationship compatibility features, personalized daily horoscope and transit forecast apps, human design and bodygraph tools, and Vedic kundli, numerology, and tarot experiences. You do not have to start from scratch either: typed SDKs, drop-in UI components, copy-paste embeddable widgets for Squarespace, Wix, Shopify, Ghost, and Webflow, a WordPress plugin, and free templates ship with every plan. Developers go from API key to a working app in about thirty minutes, and a practitioner with an existing site pastes one snippet and has a live reading running without writing any code.

Which SDKs and developer tools does RoxyAPI provide?

RoxyAPI ships typed SDKs for TypeScript, Python, PHP, C#, and Go, all auto-generated from the live OpenAPI spec so they never drift. Each SDK bundles an AGENTS.md playbook that stops AI coding tools like Cursor and Claude Code from hallucinating endpoint names. Drop-in Roxy UI web components render every response, natal wheels, kundli, dasha timelines, and tarot spreads, straight from the JSON, and the same components ship as copy-paste embeddable widgets for Squarespace, Wix, Shopify, and any site with an HTML block, so a page with no build step gets a live reading from a single snippet. Free open source starter templates take you from clone to deploy in minutes.

Can I add astrology to a WordPress site or build with no code?

Yes, three ways. The official RoxyAPI WordPress plugin adds readings to any page with a shortcode and no code. On Squarespace, Wix, Shopify, or any site with an HTML block, the copy-paste widgets at roxyapi.com/widgets embed a natal chart, horoscope, kundli, or tarot reading with one prefilled snippet or a hosted embed URL, powered by a browser-safe publishable key and no backend. And for custom builds, the drop-in Roxy UI web components work in plain HTML, React, Vue, Svelte, or Angular and render every API response from a single tag, themeable with CSS variables.

Is RoxyAPI open source, and can I use it commercially?

The SDKs, Roxy UI components, the copy-paste embeddable widgets built on them, and the starter templates are MIT licensed and free to use in commercial products. The calculation engine carries no AGPL copyleft, so you can ship a closed-source commercial app without the licensing restrictions that come with the older ephemeris libraries most incumbents are built on. RoxyAPI is also stateless: it stores no birth data or user profiles, so your users and the personalization you build on them stay your moat, not ours.

Who is behind RoxyAPI?

RoxyAPI is built by a small, independent team of senior engineers, each with over 15 years building consumer and lifestyle products, including at some of the biggest names in the industry. Groundwork on the in-house Roxy Ephemeris calculation engine began in 2020, the platform launched in 2024, and it has grown by word of mouth since, verified throughout against NASA JPL Horizons. The platform crossed 1 million cumulative API requests in March 2026, and the full dated figures are published on the transparency report.

Is there a free way to try RoxyAPI before paying?

Yes. The interactive API reference returns real production responses, not signup-locked sandbox data, so you can audit the output before you buy. More than twenty free calculators and open source templates let you see exactly what each endpoint returns with no key required.

How much does RoxyAPI cost?

Plans start at $39 per month for 25,000 requests, and every plan includes all 12 domains, every endpoint, Remote MCP, the typed SDKs, the UI components, the copy-paste embeddable widgets, and the templates. Because the whole catalog is bundled, the unit that matters is the price per domain: $2.70 per domain per month on annual billing, against $12 or more per month for a typical single-domain astrology API. Pricing is flat, so one request equals one quota unit whether it arrives over REST or Remote MCP, and a complete natal chart or kundli returns in a single call rather than several separately billed ones.
