Getting started overview

The aztro API provides a free, public service for retrieving daily horoscope predictions. It is designed for straightforward integration, making it suitable for applications requiring astrological content without complex authentication or setup. The API operates as a single REST endpoint, accessible via HTTP POST requests, and does not require an API key or any form of authentication. This simplicity allows developers to quickly add horoscope features to their projects.

To begin using aztro, the primary steps involve understanding the API's request parameters and constructing a basic HTTP POST request. Since no account creation or key management is necessary, developers can proceed directly to making API calls. The API supports various programming languages, with examples often available to facilitate integration.

This guide will walk you through the process of making your first successful call to the aztro API, covering the necessary request format and common considerations.

Create an account and get keys

A distinctive feature of the aztro API is that it does not require users to create an account or obtain API keys. This design choice simplifies the onboarding process significantly, removing common barriers to entry such as registration forms, email verification, and credential management. Developers can begin making requests to the API immediately upon understanding its structure.

The absence of API keys means there are no rate limits enforced through individual user identification, nor is there a need to manage key rotation or security. This makes aztro particularly attractive for rapid prototyping or applications where tracking individual API usage is not a primary concern. However, it also implies that developers are responsible for managing their own request volume to ensure fair use and prevent potential IP-based blocks if requests become excessive. While the official documentation does not specify explicit rate limits, adherence to general API rate limiting best practices is advisable to maintain service availability.

Therefore, to use aztro, you do not need to perform any steps related to account creation, dashboard navigation, or API key generation. You can proceed directly to making API calls.

Your first request

Making your first request to the aztro API involves sending an HTTP POST request to its single endpoint. The API expects two main parameters: sign and day, which should be sent in the request body.

API endpoint

The base URL for the aztro API is https://aztro.sameerlahore.me/.

Request parameters

  • sign (required): The astrological sign for which you want the horoscope. Valid values include: aries, taurus, gemini, cancer, leo, virgo, libra, scorpio, sagittarius, capricorn, aquarius, pisces.
  • day (required): The day for which you want the horoscope. Valid values include: today, tomorrow, yesterday.

Example request (cURL)

The following cURL command demonstrates how to request the horoscope for Gemini for today:

curl -X POST \
  --data-urlencode "sign=gemini" \
  --data-urlencode "day=today" \
  https://aztro.sameerlahore.me/

Example request (JavaScript - Fetch API)

For web applications, the Fetch API can be used to make the request:

fetch('https://aztro.sameerlahore.me/', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/x-www-form-urlencoded'
  },
  body: new URLSearchParams({
    'sign': 'gemini',
    'day': 'today'
  })
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error fetching horoscope:', error));

Example response

A successful request will return a JSON object containing the horoscope data. The structure typically includes fields like description, mood, color, lucky_number, lucky_time, and compatibility.

{
  "date_range": "May 21 - June 20",
  "current_date": "May 29, 2026",
  "description": "Today, your communication skills are highlighted...",
  "compatibility": "Libra",
  "mood": "Optimistic",
  "color": "Yellow",
  "lucky_number": "3",
  "lucky_time": "11am - 12pm"
}

For additional language examples, consult the aztro API homepage, which provides code snippets for Python, PHP, Ruby, Go, Java, and R.

Common next steps

After successfully making your first request to the aztro API, consider these common next steps to integrate the data into your application:

  1. Integrate into your application logic: Parse the JSON response and display the relevant horoscope information within your user interface. This might involve dynamically updating text fields, populating daily widgets, or sending push notifications.
  2. Error handling: Implement robust error handling to manage cases where the API might return an error (e.g., invalid sign, network issues). While aztro is simple, any external API can experience temporary outages or unexpected responses.
  3. User input validation: If your application allows users to select their zodiac sign, ensure that the input is validated against the list of aztro's supported signs before making the API call.
  4. Caching strategies: To reduce redundant API calls and improve performance, implement caching for horoscope data. Since daily horoscopes change only once per day, you can store responses for a 24-hour period. This also helps in adhering to unspoken rate limits.
  5. Explore personalization: Use the horoscope data to enhance personalization features in your application. For example, if your application has a user profile with their astrological sign, you can automatically fetch and display their daily horoscope upon login.
  6. Consider alternatives/enhancements: While aztro is free and simple, if your project requires more advanced astrological data, historical data, or higher reliability guarantees, you might explore commercial alternatives. For example, some APIs offer detailed planetary positions, birth chart analysis, or higher request limits, often with associated costs and authentication requirements.

Troubleshooting the first call

If your first call to the aztro API does not return the expected results, consider the following troubleshooting steps:

  • Verify HTTP method: Ensure you are sending a POST request. The aztro API strictly requires POST for horoscope retrieval. Using GET will result in an error or an empty response.
  • Check request body format: The sign and day parameters must be sent in the request body, typically as application/x-www-form-urlencoded. If you are using JSON in the body, it will not be parsed correctly.
  • Validate parameter values: Double-check that the sign value is one of the 12 valid astrological signs (e.g., gemini, not Gemini or GEMINI) and that day is either today, tomorrow, or yesterday. Incorrect casing or spelling will lead to invalid responses.
  • Network connectivity: Ensure your development environment has stable internet access and can reach https://aztro.sameerlahore.me/. Proxy settings or firewalls might interfere with outgoing requests.
  • Review console/network logs: Check your browser's developer console (for client-side JavaScript) or your terminal output (for cURL/server-side languages) for any error messages, HTTP status codes other than 200 OK, or network failures.
  • Content-Type header: Confirm that your request includes the Content-Type: application/x-www-form-urlencoded header. While some clients might infer this, explicitly setting it ensures correct parsing by the API.
  • SSL/TLS issues: Ensure your client supports HTTPS and the necessary SSL/TLS protocols to connect securely to the endpoint.
  • Refer to official documentation: The aztro API documentation provides the most up-to-date and authoritative information on endpoint behavior and expected parameters. Any changes to the API would first be reflected there.
