The target model

target controls the size a template renders at. One curated template can render into several sizes, so the same content produces an Instagram square, a story, or an OG card without re-authoring anything.

Named sizes

Pass target as one of the named screen sizes on POST /v1/render:

target	Aspect	Typical use
square	1:1	Feed posts, profile imagery
portrait	4:5	Tall feed posts
story	9:16	Stories / Reels / vertical
landscape	16:9	Wide banners, video frames
og	1.91:1	Open Graph / link-preview cards

A template advertises which sizes it supports in its ratios array (see Find a template). Requesting a target the template doesn't support, or an unknown size, is rejected with 422.

curl -sS -X POST "https://api.lemtika.com/v1/render" \
  -H "Authorization: Bearer $LEMTIKA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "templateId": "tmpl_og_card", "values": { "headline": "Launch day" }, "target": "og" }' \
  -o card.png

Omitting target

target is optional. Omit it to render at the template's native authored dimensions. For the current all-square catalog, that is identical to square.

Output format

target is the size; format is the file type. format defaults to png and also accepts pdf, jpeg, svg, and webp. For webp, an optional quality (1–100, default 80) controls lossy compression. See Render for the full request body.
