info:
  title: Art Blocks Generator Media API
  description: Returns an iframe-able live view of the generative artwork associated with a given Art Blocks token. The live view runs the artist's on-chain script in the browser using the token's deterministic hash as a seed, producing the canonical on-chain artwork output. Useful for embedding live artwork in external applications and marketplaces.
