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, or WebP. It differs from an AI image API, which generates pictures from text prompts. ### How much does an image generation API cost? 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. ### Do I need webhooks or polling to generate images? 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. ### What image formats does the API return? PNG, JPEG, and WebP. You choose the output format per request. ### Is there a free image generation API tier? Yes. Imejis.io includes 100 free API calls every month, permanently, with no credit card required and no watermarks. ### Can an AI agent generate images with Imejis? Yes. Imejis runs a remote MCP server, so Claude, ChatGPT, or Cursor can design a template and render a real PNG or SVG directly. Your agent already writes the copy. Now it renders the image. See the AI Agents page for setup. ## Start generating images today 100 free API calls per month. No credit card required. Full feature access.
