Musclegram API
Render themed muscle diagrams and query the stable muscle ids each figure and side can highlight.
The Musclegram API connects a finished anatomy image to the muscle catalogue behind it. Use a publishable URL for the image and the secret-authenticated data API when your interface needs labels, filters, or coverage information.

Render a muscle diagram
Choose the figure, side, highlights, crop, and rendered width.
List muscles
Page, search, and filter muscles by region and artwork coverage.
Get a muscle
Read one muscle and every figure-and-side combination that draws it.
List muscle vocabularies
Discover accepted regions, figures, and sides with record counts.
Shared ids remove the mapping layer
The data API’s id is passed directly to primary or secondary. A picker that
loads /v1/muscles?figure=male&side=front can offer only values guaranteed to light
up on the image already on screen.
