Image generation API
One call in, a finished image out. Design a template once, then render thousands of on-brand images from a single API call — finished image back in under 2 seconds, no webhooks, no polling. From $14.99/mo, a third of what Bannerbear charges.
One call in,a finished image out.
Design a template, send your data, get the image back. Three steps, one endpoint.
Design a template
Use the drag-and-drop editor to create your image layout. Mark text, images, and colors as editable fields.
Send data via API
POST your data as JSON to a single endpoint. Only send the fields you want to change.
Get your image
The API returns a finished image (PNG, JPEG, WebP, or single-page PDF) in under 2 seconds. No webhooks, no polling.
Example API call
curl -X POST 'https://render.imejis.io/v1/YOUR_TEMPLATE_ID' \
-H 'dma-api-key: YOUR_API_KEY' \
-H 'Content-Type: application/json' \
-d '{
"headline": { "text": "Summer Sale" },
"price": { "text": "$29.99" },
"product_image": { "image": "https://example.com/shoe.jpg" }

Image generation API — FAQ.
An image generation API creates finished images from a template and dynamic data. You design a template once, then send data (text, images, colors) to an endpoint and get back a rendered PNG, JPEG, WebP, or PDF. It differs from an AI image API, which generates pictures from text prompts.
Imejis.io starts free with 100 calls per month, then $14.99/mo for 1,000 calls ($0.015 per image), dropping to $0.0007 per image on higher tiers. Most competitors start between $19 and $54 per month.
No. Imejis.io returns the finished image directly in the API response, usually in under two seconds. There is nothing to poll and no webhook to configure.
PNG, JPEG, WebP, and single-page print-ready PDF. You choose the output format per request (JPEG by default), tune JPEG quality from 1-100, and every render can be delivered as a signed, time-limited download URL.
Yes. Add size variations to a design, then pass `?variation=<id>` on the render call to get that exact size back from the same template. One template can drive an OG image, a square social post, and a vertical story, with no duplicate designs to keep in sync.
Three ways, set with the `delivery` parameter. `delivery=stream` (the default) returns the image bytes inline. `delivery=hosted` and `delivery=signed` instead store the render and return a JSON body with a URL, ready to drop into an email, a webhook, or a dashboard. Signed URLs expire; set the window with `expiresIn` in minutes (default 60, up to 7 days).
Yes. Imejis.io includes 100 free API calls every month, permanently, with no credit card required and no watermarks.
Yes. Imejis runs a remote MCP server, so Claude, ChatGPT, Gemini, Cursor, or Google Antigravity can design a template and render a real PNG, JPEG, WebP, or PDF directly. Your agent already writes the copy. Now it renders the image. See the AI Agents page for setup.
