Birth Chart Blueprint Audio Report

The audio download-url is valid for 24 hours from the time it is issued. Download or save the MP3 before the link expires.

The Birth Chart Blueprint Audio Report API creates a narrated Western astrology MP3 report from the supplied birth details. It explains how the birth chart is built, including the Sun, Moon and Rising signs, the chart ruler, dominant elements and modes, and the strongest planets. The reading connects these placements to the person’s character and the central pattern in their chart.

The API accepts the request immediately and returns a request-id. When the audio is ready, its download-url is delivered by a POST request to the supplied public HTTPS webhook-url. The callback also reports a failed job when generation cannot be completed.

Customize tone, language, voice-id and duration-minutes using the parameter allowed values. Supported durations are 1, 3, 5, 7 and 9 minutes; 3 minutes is the default. The default language follows a supported Accept-Language header, otherwise en.

Authenticate with the x-astrologyapi-key header, or HTTP Basic authentication using userId:apiKey. Send the request body as application/json.
