Natal chart, transit, horoscope, tarot, dream and crystal readings inside her online courses
The catalogue
Western and Vedic astrology, forecast, human design, tarot, numerology and the rest of the catalogue, from one typed API: a Remote MCP server per domain, SDKs for TypeScript, Python, PHP, C#, Go, and Rust, UI components, copy-paste widgets and free templates. One flat plan covers all of it, in 10+ languages.
One flat plan, all inclusive
Typed API: a complete result in one call, from a live typed OpenAPI spec
Remote MCP: hosted agent tools over Streamable HTTP, no local setup
Typed SDKs: TypeScript, Python, PHP, C#, Go, and Rust, generated from the spec
UI components: natal wheels, kundli, bodygraphs, and spreads rendered from the response
Embed widgets: paste one snippet on any site with a browser safe publishable key
Templates: MIT licensed apps to clone, white label, and ship as your own
Multilingual i18n: full interpretation text in 10+ languages, included in every plan
Every surface, across all 18+ domains, under one flat subscription. No per-product fees, no per-request or token costs.
| Capability | RoxyAPI | Legacy astrology APIs | DIY open source libraries |
|---|---|---|---|
| Platform | |||
Count domains as distinct systems, not as features of one. Horoscopes, natal charts, synastry and compatibility are all astrology and count once here, so an honest total can read smaller than a padded one, and a high endpoint count usually means one result split across separately billed calls. | |||
One plan, 18+ domainsAstrology, vedic astrology, forecast, human design, numerology, tarot, and more behind a single subscription and a single API key. | Yes | Per product | One library each |
Flat request pricing1 request equals 1 unit, REST or MCP, with no credit weighting and no premium endpoint surcharges. Credit-metered providers bill a different unit: on one such published table a single birth chart draws 50 credits, so divide their allowance by the per call weight before comparing it with a RoxyAPI request quota. | Yes | Credit tables | Self hosted |
One call, complete resultA natal chart or kundli returns whole in one response instead of splitting into many separately billed calls. | Yes | Split calls | Assembly required |
New domains at no extra costEvery new domain lands inside the existing plan automatically. | Yes | New invoice | New build |
| Simple surface, advanced core | |||
One request returns a complete result, so the advanced layer lives inside the engine instead of inside your integration. RoxyAPI is built by a small, independent team of senior engineers, each with over 20 years building consumer and lifestyle products at scale, including at some of the biggest names in the industry. | |||
Western astrology past the natal chartFixed stars, asteroid goddesses, Arabic lots, Black Moon Lilith, aspect pattern detection, secondary progressions, solar arc directions, annual profections, astrocartography, relocation charts, local space, and the solar, lunar and planetary return charts. | Advanced layer | Natal and transits | Raw positions |
Classical Vedic with the reasoning attachedA yoga verdict carries the classical evidence that triggered it and the precedence rule that silenced it, so an agent can explain a judgement instead of restating a label. Shadbala, bhava bala, ashtakavarga, Arudha padas, Chara Karakas, three avastha systems, and KP sub-lords ship alongside it. | 48 verdicts, with evidence | Yoga names | Positions only |
Human Design past type and authorityVariables with Color, Tone and Base, the advanced Primary Health System layer, plus Penta for small groups, two-person connection charts, and transit overlays on a natal bodygraph. | Variables and Penta | Type and profile | No engine to fork |
Domains that compose, not just coexistHuman Design is computed FROM the western ephemeris and the I Ching hexagrams rather than bolted on as a separate product line, so every gate activation carries its hexagram, and one forecast request merges western transit events with Vimshottari dasha boundaries and biorhythm critical days into a single time ordered feed. The sidereal and tropical engines are tested to return the same sky at zero tolerance. | One shared engine | Separate products | You merge it |
| AI agent readiness | |||
Remote MCP server per domainHosted Streamable HTTP servers your agent connects to directly, no local processes, no Docker, no self hosting. | Yes | Varies | Build your own |
Token-optimized responsesOpt-in compact mode cuts LLM tokens per response by 40 to 52 percent on detailed charts. Same data, lower agent inference cost, one request. | Yes | Not offered | Not offered |
Agents integrate on their ownPoint an AI agent at roxyapi.com and it discovers every capability, the auth model, and the docs without a human in the loop. | Yes | Human setup | Human setup |
Bring your own LLMGrounded calculations for any model you run, with no per-token markup in the middle. The MIT licensed Templates, including the AI astrology chatbot, are yours to white label and build on, so the model, the system prompt, and the product stay yours. | Your voice | Markups, locked prompt | Yes |
| Verification | |||
Every claim in this section is checkable by you rather than asserted by us: the benchmark is MIT licensed and runnable against any provider, the methodology publishes the reference source for every domain and its tolerances, the playground returns real production responses with no signup, and uptime is reported by a third party we cannot edit. | |||
Edge cases found by simulation, not by your usersBoundary births run as tests on every deploy, domain by domain, among them the hour a daylight saving change skips, midnight on a solar clock for a BaZi day pillar, a Human Design node under two arcseconds past a gate line, a birth at the South Pole in the first second of 2000, and both ends of the 1550 to 2650 ephemeris span. | Pinned in tests | Found in production | Yours to find |
Maturity you can check, not years you take on trustEngine work since 2020 and production since 2024, shown as tests that pass on every deploy and a benchmark you rerun rather than as years in business or self-reported traffic. | Rerunnable proof | Years, self-reported | Upstream history |
13,957 automated tests per deploy3,683 of them are gold-standard tests pinned to a named external reference in every calculated domain, from NASA JPL Horizons for positions to the printed classical texts for rule-based systems. | Published | Not published | Varies |
Open MIT benchmark17 domains re-checked against named authorities in runnable Python, planets within 0.32 arcseconds (0.00009 degrees) of NASA JPL Horizons. Point it at any provider. | Runnable | No public artifact | Run it yourself |
Published methodologyTest corpus, tolerances, and reference sources documented in public. | Yes | Asserted only | Varies |
Proof before you payThe live playground returns real production responses, not fake sandbox data locked behind a signup. Audit accuracy and response shape first. | No signup | Signup or sandbox | Install first |
Independent uptime pageUptime is monitored by UptimeRobot, an independently run third party we cannot edit, showing 100% RoxyAPI uptime over the last six months; the SLA still promises 99.95% for the rare cases. | 100% last six months | Self reported | Yours to run |
| Developer experience | |||
Live typed OpenAPI specEvery operation ships typed request and response schemas, drift-guarded in CI. Try real production responses before paying. | Yes | Docs or exports | Read the source |
Typed SDKs in 6 languagesTypeScript, Python, PHP, C#, Go, and Rust, each bundling AGENTS.md with the method reference for coding agents. | Yes | Fewer languages | No |
Drop-in UI components@roxyapi/ui renders natal wheels, kundli, dasha timelines, tarot spreads, and more straight from the JSON, or straight from an MCP tool result inside your own AI chat (generative UI). MIT licensed, framework agnostic. | Yes | No | No |
Embeddable widgetsCopy-paste snippets with browser-safe pk_ publishable keys and origin allowlists. Works on Squarespace, Wix, Shopify, or any HTML block. | Yes | No | No |
White-label MIT TemplatesOpen source apps you can clone, brand, and ship as your own product. | Yes | No | Varies |
Editorial-grade interpretations in 10+ languagesComplete interpretation text ready to publish on blogs, brand sites, and publisher homepages, localized from one lang query parameter and included in every plan. RoxyAPI localizes the whole reading, where others translate only field labels or a daily horoscope. | Publish ready | Horoscopes mostly | Numbers only |
Usage dashboard and quota alertsThe account dashboard shows requests, quota used, average response time, and REST against MCP by domain, with a filterable request log. Email alerts fire automatically at 80 and 100 percent of the monthly quota, on every plan. | Yes | Varies | You build it |
| Licensing and privacy | |||
The AGPL exposure most teams carry was never a decision: a package manager hands you the free path, so a team installs a Swiss Ephemeris wrapper, ships a network service, and inherits copyleft without reading it. That licence is a private contract with no public registry, so ask any provider for their position in writing. | |||
Own engine, not a Swiss Ephemeris wrapperRoxy Ephemeris is built in house and reads the NASA JPL DE440 ephemeris directly, verified against NASA JPL Horizons. Legacy engines wrap Swiss Ephemeris, a desktop-era calculation library under the AGPL copyleft unless commercially licensed, and a buyer cannot verify from outside which version or licence a provider runs, so ask for the position in writing. | Roxy Ephemeris | Swiss based, licence unverifiable | Swiss based, AGPL unless licensed |
No AGPL exposureThe AGPL on Swiss Ephemeris reaches network services, so products built on unlicensed wrappers inherit the obligation whether they know it or not. Google bans AGPL dependencies outright. | None | Inherited from Swiss | AGPL common |
Commercial license on every planBuild and sell closed source apps, keep your code private, ship to any app store, white label for clients, and pass the license audits that funding rounds and acquisitions run. No source disclosure. | Yes | Varies | Copyleft terms |
Stateless calculations, your own user profilesAPI request bodies are never persisted. Responses derived from submitted data may be cached for up to 24 hours; Cache-Control: no-store bypasses the cache. Usage metadata retention is in /policy/privacy. Your application keeps user profiles and memory. | Yes | Accounts and logs | Self hosted |
EU data residency with an Article 28 DPA on every planStored data stays in Germany, inside the EU, on every plan and for every customer, so an EU buyer gets EU residency by default instead of paying for a regional tier. The processor contract, EU Standard Contractual Clauses, security measures, dated subprocessor register, and breach notification terms are all published, so procurement can review them without contacting us. | Germany, all plans | Enterprise or on request | Yours to write |
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.
From zero to a working app in one sitting.

View Pricing & Get API KeyHi, I am Rosie, your guide to the RoxyAPI insight tools.
Ask me to read your birth chart, pull a card, or map your numbers, and I will interpret what it means for you. Unlike most AIs, I never make the numbers up: every reading runs on real, verified calculations. Curious about the API, pricing, or docs instead? Ask me that too.
