Astroask

This astrology API gives developers structured access to both Vedic and Western astrology data from a single API. It provides endpoints for planets, dashas, panchanga, natal charts, transits, compatibility matching, numerology, and chart images, allowing teams to build astrology features without stitching together multiple providers.

The API is designed for software integrations rather than manual data cleanup. Responses use structured JSON with numeric values returned as real numbers at full double precision, booleans preserved as booleans, and standard HTTP status codes for errors. Rate-limit headers are also provided, making the API suitable for applications that need predictable programmatic handling.

Key Features

Vedic and Western Astrology

Access both major astrology systems through one API and a consistent development workflow.

The API covers:

• Vedic astrology
• Western astrology
• Planetary calculations
• Dashas
• Panchanga
• Natal charts
• Transits
• Compatibility matching
• Numerology
• Chart images

This reduces the need to integrate and normalize data from separate astrology providers.

94 Astrology Endpoints

The platform provides 94 endpoints, with each endpoint focused on a specific calculation or data operation.

Vedic and Western astrology capabilities are available within the same overall API schema, making it possible to build different astrology features without maintaining separate integrations.

Swiss Ephemeris Precision

Astrological calculations use Swiss Ephemeris data with full double-precision ephemeris calculations.

This provides developers with numeric results at the precision level needed for applications that perform their own calculations, rounding, comparisons, or downstream analysis.

Typed JSON Responses

The API returns structured JSON designed to be consumed directly by software.

• Numeric values remain JSON numbers
• Boolean values remain booleans
• Full double-precision values are preserved
• Standard HTTP status codes communicate errors
• Rate-limit headers are available

Keeping types intact makes it easier for applications to branch on results, recompute values, or apply additional rules without first cleaning up the API response.

Batch Requests

Send up to 50 API calls in a single HTTP request.

Batching can be useful when an application needs several calculations at once while retaining per-item pricing rather than changing the underlying calculation model.

Astrology Chart Images

Generate astrology charts directly from the API without building your own chart-rendering system.

Chart image output supports:

• North Indian charts
• Western wheels
• SVG
• PNG

This makes it possible to incorporate visual charts into user-facing applications alongside the underlying structured data.

21 Languages

The API supports localized output through a dedicated language parameter.

With 21 supported languages, developers can build multilingual astrology experiences without having to maintain separate translation layers for API responses.

Built For Developers

The API is designed for teams building astrology functionality into applications, tools, research systems, or internal products.

Instead of returning information intended primarily for human reading, it focuses on predictable structured output that applications can consume directly.

This makes it suitable for developers building matching engines, astrology research pipelines, personalized user experiences, and other software that needs programmatic access to astrology calculations.

Common Use Cases

Astrology Applications

Add natal charts, planetary positions, dashas, transits, and other astrology calculations to an existing application.

Compatibility and Matching

Use compatibility endpoints inside relationship or matching products, with access to the checks and cancellations behind certain verdicts.

Research Pipelines

Pull structured numeric astrology data into research or analytical workflows where calculations may need to be recomputed or processed further.

Personalized Astrology Products

Build user-facing experiences around natal charts, transits, panchanga, numerology, and other personalized calculations.

Multilingual Astrology Tools

Return localized astrology information through the API's language parameter across supported languages.

Chart Generation

Generate North Indian or Western chart images as SVG or PNG for use inside applications, reports, or user profiles.

Explainable Astrology Results

Some endpoints expose the reasoning behind their results rather than returning only a final label.

For example, dosha and compatibility endpoints can include the reference checks and cancellations that contributed to the verdict.

This allows developers to:

• Show users how a result was determined
• Build their own presentation layer
• Apply additional rules
• Inspect the underlying checks
• Avoid treating a verdict as an unexplained label

This is particularly useful for applications where users need more context around compatibility or dosha results.

API Documentation

The developer documentation includes OpenAPI along with generated reference material, providing a structured way to explore endpoints and integrate the API into software projects.

Pricing And Trial

The trial includes 5,000 API requests or 14 days, giving developers an opportunity to test the calculations and integration before moving to ongoing usage.

Why It Matters

Building astrology functionality can require combining planetary calculations, chart generation, compatibility logic, localized output, and multiple astrology systems. When those capabilities come from different providers, developers also have to normalize schemas and data types across integrations.

This API puts Vedic and Western astrology into one structured interface, with typed JSON, double-precision calculations, batch requests, multilingual output, and chart generation. For teams building astrology software, that creates a more direct path from calculation to application feature.

Build Astrology Features With One API

Access Vedic and Western astrology through 94 structured endpoints covering planets, charts, dashas, panchanga, transits, compatibility, numerology, and chart images. With Swiss Ephemeris precision, typed JSON, batch requests, 21-language output, and OpenAPI documentation, the API gives developers the building blocks for integrating astrology directly into their applications.
