First OG image in 5 minutes

Render a social share image from your data — then prove it's deterministic.

1. Render

Mint a key at Settings → API keys, export it as $LEMTIKA_API_KEY, and post your copy to the seeded tmpl_og_card template at the og target (1200×630).

render an OG image

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": "Ship faster", "metric": "10k users" },
        "target": "og"
      }' \
  -o og.png

The response is a ready-to-share image/png, written to og.png.

2. Prove it's deterministic

Same template + same values => same bytes, every time. Render twice and diff:

render twice, diff the bytes

# Render the same request twice…
curl ... -o render_1.png
curl ... -o render_2.png

# …and diff the bytes
sha256sum render_1.png render_2.png

9f2a3c1b8e…e4c7 — identical, 0 bytes differ

That determinism is what makes Lemtika safe to wire into automations — no per-call generative gamble. Wire it into your build, a webhook, or an agent and every render is predictable.
