What is the Astrology Chat API and how is it different from a regular chatbot?

The Astrology Chat API is an agentic platform — not just a chatbot wrapper. When you send a message, the server autonomously decides which of 16 astrology tools to invoke (natal charts, transits, synastry, etc.), executes them against our 82 calculation endpoints, and synthesizes a grounded response. Unlike generic chatbots that hallucinate astrology data, every interpretation is backed by real ephemeris calculations. The entire agent loop runs server-side in a single API call.

Can I use the OpenAI Python or TypeScript SDK with this API?

Yes — that's the core design principle. We implement the standard OpenAI /chat/completions protocol, so you use the official OpenAI SDK in any language: TypeScript (openai npm package), Python (openai pip package), Go, Rust, or any HTTP client. Just change the base URL to our endpoint. Your existing OpenAI code works with minimal changes. This also means instant compatibility with LangChain, Vercel AI SDK, and any OpenAI-compatible framework.

What LLM models are supported with BYOK?

BYOK supports three providers with 50+ models. OpenAI: GPT-5, GPT-5-mini, GPT-5-nano, o3, o4 families. Anthropic: Claude Opus 4, Sonnet 4, Haiku 4. OpenRouter: any model they host — Gemini 3, Grok 4, Llama, Mistral, Qwen, and more. You pass your own API key and model ID. The platform handles all provider-specific quirks (like reasoning model parameter differences) automatically.

How much does each chat turn cost in credits?

Each turn has two cost components: platform credits + endpoint credits for tool calls. Hosted mode: 25 credits/turn (LLM included) + endpoint credits (e.g. natal = 1, transit = 1, astrocartography = 5, PDF = 35). BYOK mode: 2 credits/turn + same endpoint credits + your LLM provider costs. Example: a natal chart interpretation = 25 + 1 = 26 credits hosted (~$0.02), or 2 + 1 = 3 credits BYOK (~$0.002) + ~$0.003 LLM cost. On Professional plan ($37/month, 55,000 credits) that's ~2,100 hosted turns or ~18,000 BYOK turns. Free tier: 50 requests/month.

How does multi-subject chat work for synastry and compatibility?

Pass multiple subjects in the astrology.subjects array, each with a semantic ID ('me', 'partner', 'child') and birth data. The LLM references subjects by ID when calling tools — the server resolves IDs to full birth coordinates. This enables synastry, composite charts, and multi-person analysis in a single conversation. No competitor supports more than one subject per session.

Can the chat generate PDF reports and SVG chart images?

Yes — binary artifacts are a unique feature. Ask 'Generate my natal chart' and the agent calls the render_natal tool, produces an SVG (or PNG/PDF), stores it as an artifact, and returns a shareable URL. Same for PDF natal reports — multi-page professional documents with wheel visualization, interpretations, and themes. Artifacts are stored in Supabase with 24-hour retention and shareable URLs.

How fast is the Astrology Chat API compared to alternatives?

Our calculation layer responds in under 300ms per tool call. Total response time (calculation + LLM generation) is typically 2-5 seconds with streaming. Competing astrology chat solutions average 8-24 seconds per response, even on premium tiers. With streaming, our users see the first tokens in under 2 seconds while the agent continues working.

What are the SSE streaming extension events?

Beyond standard OpenAI text chunks, we emit custom SSE events: tool_start (when the agent begins calling a tool — your UI can show 'Calculating natal chart...'), tool_end (when the tool returns — with execution time), and astrology.error (if a tool fails gracefully). These enable rich, real-time UIs that show the agent's reasoning process as it works.

How do sessions and conversation memory work?

Pass astrology.session_id in your request. On the first turn, the server creates a Redis-backed session. On subsequent turns with the same ID, the server loads prior messages and subjects before processing your new message. Sessions have a 24-hour sliding TTL — each interaction extends the window. The server handles message compression for long conversations, so you don't need to manage context windows.

What programming languages and frameworks are supported?

Any language with an HTTP client works, but OpenAI SDKs provide the best experience: TypeScript/JavaScript (openai), Python (openai), Go (openai-go), Rust, C#, Java, PHP, Ruby. Framework compatibility: LangChain, LlamaIndex, Vercel AI SDK, Semantic Kernel, AutoGen, CrewAI, Haystack — anything that speaks the OpenAI protocol. Most developers integrate in under 30 minutes.

Is this just a GPT wrapper or does it use real astronomical data?

Every astrological interpretation is grounded in real ephemeris calculations. When the agent calls charts_natal, it computes actual planetary positions using the Swiss Ephemeris — the same engine professional astrology software uses. The LLM receives real chart data (planet positions, house placements, aspects with exact orbs) and synthesizes interpretations from that data. No hallucinated planetary positions, no made-up aspects.

How do I control the response style and length?

Three layers of control: 1) System message — set any personality ('warm Jungian psychologist', 'concise British classicist', etc.). 2) astrology.defaults.detail_level — 'brief' (under 100 words), standard (200-350 words), or 'detailed' (500-800 words). 3) astrology.defaults.tradition — classical, psychological, event-oriented, or universal. The user's explicit instruction ('briefly' or 'in detail') overrides everything.

What astrology traditions and house systems are supported?

Four interpretation traditions: Classical (Hellenistic/medieval), Psychological (Jungian), Event-Oriented (horary/electional), and Universal (balanced). Twenty-three house systems including Placidus, Koch, Whole Sign, Equal, Campanus, Regiomontanus, Porphyry, and more. Set via astrology.defaults.house_system — the server applies it to all tool calls automatically.

Can I white-label this as my own product?

Absolutely. The system prompt (messages[0] with role='system') controls the entire personality. Set your brand voice, astrologer persona, language style — the user never sees our branding. BYOK gives you cost control. Session persistence enables subscription models. The standard pricing plans support commercial redistribution.

What happens if a tool call fails during the conversation?

Graceful degradation. If a tool returns an error (invalid birth data, unsupported calculation), the agent receives the error message and adapts — it might try a different tool, ask the user for clarification, or provide a partial answer. With streaming, you receive an astrology.error event. The conversation doesn't crash; the LLM handles errors conversationally, like a human astrologer would.

Can I build an astrology widget with Lovable, Claude Code, or Cursor?

Yes — this is the ideal API for vibe coding. Because we implement the standard OpenAI /chat/completions protocol, AI coding tools like Lovable, Claude Code, Cursor, Windsurf, Bolt, and Replit Agent already know how to integrate it. Just prompt: 'Build an astrology chat widget using OpenAI SDK with base URL https://api.astrology-api.io/api/v3/chat'. The AI generates a working streaming chat component — birth data form, message bubbles, typing indicators — with zero manual debugging. No other astrology API offers this because they all use proprietary JSON formats that AI tools don't understand.

How does the Astrology Chat API compare to building my own with RoxyAPI or raw data endpoints?

RoxyAPI and similar data-only APIs give you raw calculation JSON — you build the entire agent layer yourself: tool schemas, LLM orchestration, error handling, session management, artifact storage. That's months of engineering. Our platform ships all of that ready-made. One API call replaces hundreds of lines of agent framework code. If you already use LangChain or CrewAI, our endpoint plugs in as a single tool — your existing agent framework handles the rest.

What Is Astrology Chat API? Complete Developer Guide

Everything you need to build AI-powered astrology experiences

What if you could add a fully-functional astrology AI agent to your app with a single API call? That's exactly what the Astrology Chat API does. It's not just a chatbot endpoint — it's a complete agentic platform that runs the entire tool-calling loop server-side. You send a user message, and the server autonomously decides which of 16 astrology tools to invoke, resolves birth chart data from subject IDs (no hallucinated dates), generates PDF reports or SVG charts as binary artifacts, and returns a coherent response — all through an OpenAI-compatible /chat/completions endpoint. That means you can use the standard OpenAI SDK in TypeScript, Python, Go, or any language. No custom integration code. No building your own agent framework. No managing tool schemas. Existing astrology chat solutions charge $0.25-$0.87 per query, take 8-24 seconds to respond, lock you into proprietary models, and use custom JSON formats that require bespoke integration code. We're the only platform that ships a ready-made agent with BYOK support — choose your own LLM from GPT-5, Claude, Gemini, Grok, or any of 50+ models on OpenRouter.

How Does the Agentic Chat API Work?

The Astrology Chat API works like a specialized AI agent that happens to know astrology deeply.

Here's the flow: 1) You send a message via the standard OpenAI /chat/completions endpoint.

2) The server injects astrological context — your subjects' birth data, active tools, language preferences.

3) The LLM decides which tools to call (natal chart calculation, transit analysis, synastry report, etc.).

4) The server executes those tools internally against our 82 astrology endpoints — no extra API calls from your side.

5) Tool results are fed back to the LLM for synthesis.

6) You receive a coherent, grounded interpretation with real planetary data.

The entire tool loop runs server-side in a single request.

You never see tool-call messages — just the final answer.

With streaming enabled (SSE), you also get real-time extension events like tool_start and tool_end, so your UI can show 'Calculating transit chart...' while the agent works.

What Is BYOK and Why Does It Matter?

BYOK — Bring Your Own Key — means you choose which LLM powers your astrology agent.

Every other astrology chat solution on the market locks you into a single proprietary model with no alternatives — some don't even disclose which model they use.

With our BYOK endpoint (/chat/completions/byok), you pass your own API key and model ID.

We support three providers: OpenAI (GPT-5, GPT-5-mini, GPT-5-nano, o3, o4), Anthropic (Claude Opus 4, Claude Sonnet 4, Claude Haiku 4), and OpenRouter (50+ models including Gemini 3, Grok 4, Llama, Mistral, and more).

Why does this matter? Cost control — GPT-5-nano is 10x cheaper than GPT-5-pro.

Quality tuning — Claude excels at nuanced interpretation, Gemini is faster for simple queries.

Compliance — some enterprises require specific model providers.

BYOK costs just 2 credits/turn (our platform fee) plus whatever your LLM provider charges.

50+ LLM models available — you choose cost, quality, and provider

Why Is This the Only OpenAI-Compatible Option?

OpenAI compatibility means you use the standard OpenAI SDK — the same client library millions of developers already know.

No new SDK to learn, no custom HTTP client to build.

In TypeScript: new OpenAI({ baseURL: 'https://api.astrology-api.io/api/v3/chat' }).

In Python: OpenAI(base_url='...').

That's it.

Your existing code for ChatGPT works with minimal changes.

This also means instant compatibility with every framework built on OpenAI's protocol: LangChain, LlamaIndex, Vercel AI SDK, Semantic Kernel, AutoGen, CrewAI.

If your framework speaks OpenAI, it speaks Astrology Chat API.

No other astrology provider offers this — existing solutions use custom endpoints with proprietary request/response shapes, requiring bespoke integration code for every platform you support.

Works with any OpenAI SDK — TypeScript, Python, Go, Rust, and every AI framework

Perfect for Vibe Coding — Build Astrology Widgets in Minutes

Because our API uses the standard OpenAI protocol, every AI coding tool already knows how to work with it.

Tell Lovable 'Build me an astrology chat widget using this API' and it generates a working React component — streaming UI, birth data form, chat bubbles, the works.

Claude Code and Cursor can scaffold a full integration in a single prompt because they understand the OpenAI SDK natively.

No custom adapters, no obscure documentation, no debugging proprietary JSON formats.

The same applies to Windsurf, Bolt, Replit Agent, and any AI tool that can write code against OpenAI's API.

This is what makes our platform uniquely suited for vibe coding: you describe the widget you want, the AI builds it, and it works on the first try — because the underlying API is the same protocol these tools were trained on.

Vibe coders are shipping astrology apps in hours, not weeks.

Chat widgets, compatibility checkers, daily horoscope generators, natal chart interpreters — all built by describing what you want to an AI coding assistant.

What Can the 16 Agent Tools Do?

The platform exposes 16 tools that the LLM can autonomously invoke during a conversation.

These are auto-generated from our 82 existing API endpoints using a dynamic registry — only endpoints tagged 'chat-safe' become tools.

The tools cover: Analysis (3 tools) — natal reports with multi-section interpretations, lunar analysis with moon phases and mansions, synastry reports with relationship index scores.

Chart Calculations (4 tools) — natal, synastry, composite, and transit charts with full planetary positions and aspects.

Chart Rendering (4 tools) — natal, synastry, transit, and composite charts as SVG, PNG, JPG, WebP, or PDF.

Generated charts are stored as binary artifacts with shareable URLs.

Data (3 tools) — current planetary positions, ephemeris for any date, and aspect matrices.

Horoscope (1 tool) — personalized daily horoscope with 6 life areas, ratings, and planetary influences.

PDF (1 tool) — professional multi-page natal report with wheel visualization, interpretations, and themes.

Adding new tools requires zero code changes to the chat endpoint — just tag an existing endpoint as 'chat-safe'.

How Do Multi-Subject Sessions and Artifacts Work?

Two features no competitor offers: multi-subject sessions and binary artifacts.

Multi-subject means you can pass multiple birth charts in a single conversation — for example, 'me' and 'partner'.

The LLM references subjects by their semantic ID when calling tools, and the server resolves them to full birth data.

This enables synastry analysis, composite chart comparisons, and family dynamics — all in one chat session, without re-sending birth data.

No other chat API supports more than one subject per conversation.

Binary artifacts let the chat generate downloadable files.

Ask 'Generate my natal chart' and receive an SVG chart image.

Ask 'Create a PDF report' and get a professional multi-page document.

Artifacts are stored in Supabase with shareable URLs and 24-hour retention.

Sessions persist via Redis with a 24-hour sliding TTL.

Pass the same session_id across turns and the server restores conversation history, subjects, and context — true multi-turn memory without client-side state management.

Multi-subject sessions and binary artifacts — both unique to our platform

Performance and Pricing vs Competitors

Let's talk numbers.

The fastest competing astrology chat solutions take 8-12 seconds per response.

Standard-tier plans on the market average 19-24 seconds.

Our calculation layer responds in under 300ms — total response time depends only on LLM speed, typically 2-5 seconds with streaming.

That's 4-10x faster.

On pricing, alternatives charge $0.25-$0.87 per AI query — on top of monthly subscription fees.

Our pricing has three components: (1) platform credits per turn — 25 hosted or 2 BYOK, (2) endpoint credits for each tool the agent calls (e.g.

natal chart = 1 credit, astrocartography = 5 credits, PDF report = 35 credits), and (3) your own LLM costs if using BYOK.

Example: a natal interpretation turn costs 25 + 1 = 26 credits hosted (~$0.02), or 2 + 1 = 3 credits BYOK (~$0.002) plus ~$0.003 LLM cost.

That's 10-100x cheaper per conversation turn than alternatives.

We include chat in our standard free tier: 50 requests per month, no credit card required.
