How this service works

Returns a constellation's shape as line segments in 0-1 normalized coordinates via a GET request with a name parameter.

Output

A set of line segments representing the constellation's shape, with all coordinate values normalized to the 0-1 range, suitable for rendering or further geometric processing.

Example use cases

Example prompt

“Can you get me the line segment shape data for the Orion constellation in normalized coordinates so I can draw it on a canvas?”

When to prefer

Use this endpoint when you need structured, normalized geometric data for rendering or analyzing a specific constellation's shape as connected line segments. Ideal for building star maps, educational astronomy visualizers, or any application that needs precise positional data for constellation outlines in a consistent coordinate system.

Side effects

Unknown or misspelled constellation name returns an error or empty result
Invalid or missing name parameter causes a 400 bad request
Network or server downtime on the Railway-hosted service
Payment failure via x402 protocol blocks the request
