DESIGN

J2I Studio

Visual editor for jsontoimg templates — layers, names, and the API tab.

J2I Studio is the dashboard editor. Design a template once; the Render API fills named layers on every job.

Open it from Projects → a template.

What to set up for the API

  • Layer names — unique names become keys in layers (headline, price, …). Duplicate names fail validation (DUPLICATE_LAYER_NAMES).
  • Text, image, and shape layers — override text, colors, and image URLs at render time.
  • Pages — multi-page templates export as a PDF (or one image per page depending on format).
  • Versions — pin version on a render if you need a snapshot instead of latest.

The editor API tab shows the current schema. GET /api/v1/templates/{id}/schema is the same data for agents and scripts.

Changelog

Product updates, announcements, and breaking API changes.

Image Generation
