Best Horoscope API for Developers Shipping Feeds 2026
Best horoscope API for developers: dated transit events, fact-checkable columns, eight languages, and a license to edit and white-label. By RoxyAPI.
TL;DR
- A horoscope feed is worth buying on whether it can prove itself, not on how many signs it covers: does every reading ship the dated sky events it is built from, can you re-run it and get the same text, and who owns the words once you edit them.
- Measured live against production on 2026-09-13: monthly love, career, health, and finance sections ran 116 to 199 words across twelve signs and two months, each backed by a dated events array checkable against NASA JPL Horizons or the US Naval Observatory.
- Every reading ships an events array beside the prose, dated to the second, so a publishing pipeline can wire in a fact-check step instead of trusting the text blind.
- Build this with the Astrology API in about thirty minutes, reusable for daily, weekly, monthly, and yearly feeds.
A horoscope feed buyer, a psychic network, a content aggregator, a dating or wellness app, a white-label publisher, is not evaluating an astrology API the way a chart-app developer does. The question is not "can it compute a birth chart," it is "can I schedule a month of copy today and trust it will still be accurate when it runs." That means the reading needs a reason behind every sentence, the reason needs a date attached to it, and the whole thing needs to survive an editor touching the words before it goes out under a byline.
Most of the category fails this test in one of two directions. Legacy astrology API providers sell one static paragraph keyed to the current sign of a planet, identical for everyone reading that sign for weeks at a time. AI horoscope generators go the other way: fluent, varied, and impossible to fact-check, because the model that wrote a line about a trine cannot hand back the exact date of that trine for an editor to verify. The four RoxyAPI horoscope routes, daily, weekly, monthly, and yearly, ship a column plus six section fields (overview, love, career, health, finance, advice), and every one of them names the sky events driving it, in an events array with the exact instant, the bodies, and the house it falls in for that sign.
What does each horoscope period actually return?
A daily, weekly, monthly, and yearly call from the same route family return the same seven pieces, a column plus six sections, but the depth and the extra arrays scale with the period, so a publisher picks the grain that matches how far ahead the calendar runs. Measured live against production, twelve signs per period, one date per grain (2026-10-05 for daily and weekly, October and November 2026 for monthly, all of 2026 for yearly):
| Period | Column length (measured) | Dated events measured | What only this grain adds |
|---|---|---|---|
| Daily | 125 to 152 words, median 142 | 1 event (2026-10-05, all twelve signs) | Active transits list, Moon sign and phase, an energy rating, lucky number and color |
| Weekly | 260 to 302 words, median 282 | 4 events (week of 2026-10-05, all twelve signs) | Three lucky days, three lucky numbers |
| Monthly | 503 to 659 words, median 592 | 11 to 14 events, median 12 (Oct and Nov 2026) | A week-by-week focus breakdown and a key-dates list of the real New Moon, Full Moon, and retrograde instants that month |
| Yearly | 831 to 895 words, median 883 | 15 to 17 events (2026, all twelve signs) | Every eclipse and retrograde station of the year with its house, a slow-planet theme timeline, and the best month per life area |
A scheduled importer typically pulls monthly for a rolling content calendar and yearly once, at the start of a subscriber year, for an annual feature page; daily and weekly cover a live feed or a chat surface where freshness matters more than lead time.

How does a horoscope feed API compare across providers?
Run the same evaluation a buyer would run before signing: does the text change per sign, does it carry the dates it is built from, can an editor check it, can it be re-fetched identically, what does it cost, and who owns the words after you edit them.
| What a buyer checks | RoxyAPI | Legacy astrology API providers selling generic horoscope prose | AI horoscope generators |
|---|---|---|---|
| Per-sign uniqueness | Every sign is read through its own whole-sign houses, so the same sky event produces a different sentence for each of the twelve signs | One paragraph keyed to the sign a planet occupies, reused for every subscriber of that sign, often unchanged for weeks | Genuinely different per call, but not guaranteed to stay different: two runs for the same sign can converge on similar phrasing with no control over it |
| Transit basis with dates | Every column and section is composed from aspects, sign ingresses, retrograde stations, lunations, and eclipses, each with the exact UTC instant to the second | Prose is usually keyed to the current sign of a planet for the period, without the aspect or ingress dates that produced it | A model can mention a transit if it is told about one, but the output alone gives no independently checkable date |
| Fact-check evidence | An events array ships beside the prose: type, bodies, angle, house, exact instant, and the window it holds open | No machine-readable event list ships with the text; checking it means re-deriving the astrology yourself | Whatever grounded the answer is not returned in a checkable form unless the app wraps the call in its own retrieval step |
| Reproducibility for scheduling | Deterministic: the same sign and period returns byte-identical text on every call, so a piece approved a month ahead is the piece that runs | Fixed for its stated period, but the period is usually the whole month rather than a specific day | Not guaranteed byte-identical across calls unless the vendor pins a fixed seed and prompt version, which most consumer-facing generators do not expose |
| Languages | Eight languages, each composed natively in its own grammar, not machine-translated after the fact | Coverage is vendor-specific and usually gated by plan tier rather than included as a base feature | Whatever the underlying model supports, with no independent check on terminology consistency |
| License to edit and white-label | Translate, edit, shorten, and rewrite the text for your product voice; white-label the computed output inside your own product; the one condition is not presenting a materially altered version as editorial content belonging to RoxyAPI | Republishing and edit rights are usually a separate negotiated contract that varies by vendor | Output ownership follows the usage terms of the model vendor itself, layered on top of whatever prompt produced it |
| Agent access over Remote MCP | One Remote MCP server per product over Streamable HTTP; an agent the buyer runs calls the same horoscope tools live, no local hosting | MCP support, where it exists at all, is typically a local or stdio wrapper the buyer has to host and maintain | The generator itself may be reachable as a chat endpoint, but grounding it in dated, checkable sky events still needs an outside source |
| Pricing shape | Flat subscription, every domain in every plan, one request equals one quota unit, from $39/month for 50,000 requests | Typically credit-weighted or priced per call, often with horoscope content behind its own add-on or higher tier | Priced per token or per generation call, so cost scales with prompt length as well as traffic |
What do legacy feeds and AI generators actually ship instead?
A legacy horoscope feed ships stability at the cost of specificity: the same paragraph runs for a sign until the editorial calendar of the vendor rotates it, which is honest about being generic but gives a publisher nothing to point to when a reader asks why the reading published today mentions a retrograde. An AI horoscope generator ships specificity at the cost of stability: ask it twice and the wording moves, which is fine for a one-off chat reply and a real problem for a piece an editor reviewed on Monday and a CMS publishes on Friday.
Both failure modes trace back to the same missing piece: neither category ships the dated event list a reading rests on, so neither can be fact-checked without redoing the astrology from scratch. A buyer choosing between them is really choosing which kind of unreviewable content they would rather run.
A legacy feed is still the right call in one honest case: a single-language, single-market product that publishes one evergreen paragraph a month and has no interest in dated events or a fact-check trail. An AI generator earns its place where the copy must sound conversational and match a specific brand voice on every single reply, and byte-for-byte reproducibility across requests is not a requirement, a chatbot reply rather than a scheduled publication.
How do you fact-check a horoscope column before it runs?
Every sentence traces to a row in the events array, so an editor checks the astrology before publishing rather than trusting the prose. Pulled live from GET /astrology/horoscope/aries/monthly?date=2026-10-01 on 2026-09-13, the love field opens: "Because Venus turns retrograde on the 3rd, your eighth house is the part that moves." The matching row in events reads {"type":"retrograde-station","at":"2026-10-03T07:09:17Z","bodies":["Venus"],"sign":"scorpio","house":8,"through":"2026-11-14T00:21:35Z"}, exact instant, the sign Venus turns retrograde in, and the house that placement falls in for Aries.
That date is independently checkable two ways. First, against the physics: a planet does not actually reverse orbit, retrograde motion is an apparent effect of Earth passing a slower-moving planet, or being passed by a faster one, as explained by NASA Goddard Space Flight Center. Second, against a completely separate publisher: a long-running astrological almanac, published independently of RoxyAPI since 1792, lists the same 2026 Venus retrograde window, October 3 to November 14. A reading that is wrong about the date fails both checks at once; this one passes both.
Why does a Venus retrograde station belong in a love section specifically, and not just career or finance? Venus governs relationships, attraction, and personal values in the tradition every general-audience horoscope draws on, so a professional astrologer writing for that same almanac frames the October 2026 window as a period for reviewing relationships and spending rather than starting new ones, not a career or health signal. RoxyAPI routes a Venus event to the love section whichever house it falls in, following that same convention.
Monthly section length, love/career/health/finance, measured against production across twelve signs and two months (October and November 2026), each backed by its own dated events array. Median 178 to 187 words per field. See methodology for how every dated claim is checked.
How do you pull a publishing calendar of horoscope columns ahead of time?
Because the same sign and period always returns the same text, an editorial team can pull a month, or a year, before it runs, review it once, and publish on schedule without the copy drifting between the review and the publish date. Every subscriber requesting the same sign and period gets the same column, since no language model sits in the request path, which is also what makes a license to edit meaningful: rewrite the piece in the voice of your product once, and a re-fetch of the same sign and date will not silently change the source text underneath that edit.

});

REST, Remote MCP, or the docs MCP: which one fits a horoscope import job?
Use REST for a scheduled importer: a cron job or CMS plugin calling ?date= on a fixed schedule needs nothing more than an HTTP client and an API key, and every response is the same shape every time. Use the Remote MCP server when the caller is a runtime agent rather than a script: RoxyAPI mounts one Remote MCP server per product over Streamable HTTP, so a chatbot or content agent the buyer runs connects to the astrology server and calls the horoscope tools directly, live, with no local server to host. And when the thing writing the importer is a coding agent rather than a person, point it at the keyless docs MCP instead of the billable domain server: it reads the full endpoint and field reference and writes the request correctly on the first try, without spending a single quota unit on lookups.
What does a horoscope feed cost per sign, and what can you do with the text?
Pricing is flat rather than metered by content type: the Starter plan is $39 a month for 50,000 requests, and every one of the eighteen domains, including all four horoscope periods, is included at that price, not sold as a separate add-on. Spread the annual Starter price across every domain and the floor works out to about $1.80 a domain a month, whether a subscriber calls the horoscope routes once a day per sign or runs the full yearly forecast for all twelve.
The license answers the question a publisher actually asks: can this text run under my own byline? You may translate, edit, shorten, and rewrite the interpretation content to match the voice of your product, including into a language RoxyAPI does not ship natively, and you may white-label the computed output inside your own product. The one condition is attribution: if you materially alter the text, do not present the altered version as editorial content belonging to RoxyAPI. Results retrieved during a paid term are yours to keep and keep using after cancelling, so a published archive of past months does not need to be re-licensed later. Full terms: license.
FAQ
What is the best horoscope API for developers publishing feeds in 2026?
RoxyAPI is built for exactly this buyer: four periods (daily, weekly, monthly, yearly) with an editorial column plus six section fields, every reading backed by a dated, fact-checkable events array, in eight natively composed languages on one flat-priced key.
Does the horoscope API include the transit dates a reading is based on?
Yes. Every response carries an events array alongside the prose, with the event type, the bodies involved, the angle where there is one, the exact UTC instant, and the whole-sign house it falls in for the requested sign, so any sentence can be checked before it publishes.
Can I edit or rewrite the horoscope text before I publish it?
Yes. The license permits translating, editing, shortening, and rewriting the interpretation content to match the voice of your own product, and white-labeling the computed output inside your product. The only condition is not presenting a materially altered version as editorial content belonging to RoxyAPI.
Is the horoscope text the same every time I request the same sign and date?
Yes. Readings are deterministic: the same sign and period always return the same column and section text, because no language model sits in the request path. That is what makes scheduling a publishing calendar weeks ahead safe.
Does the horoscope API support multiple languages?
Yes, eight languages, each composed natively in its own grammar rather than translated after the fact, included on the same key at no extra cost.
Can an AI agent call the horoscope API directly without custom integration code?
Yes. The RoxyAPI astrology Remote MCP server runs over Streamable HTTP with no local setup, so an agent built on Claude, ChatGPT, or a framework like LangChain can call the same horoscope tools a REST integration would use, live, during a conversation.
Building a feed worth publishing
A horoscope feed is only as good as the ability of a reader, or an editor, to check it, and that is the one thing most of the category does not ship. The four RoxyAPI horoscope routes name the dated sky events behind every column and section, return the same text on every re-fetch, and license the words for you to edit and run under your own name.
