How this service works

Creates images using OpenAI's image generation models. Supports text-to-image generation with customizable size, quality, and style parameters.

Output

Returns an array of generated image objects (at least one), each containing either a URL linking to the generated image or a base64-encoded JSON string of the image data, along with a Unix timestamp of when the images were created.

Example use cases

Example prompt

“Generate a photorealistic image of a red fox sitting in a snowy forest at dusk, 1024x1024 size, using the dall-e-3 model, and give me the URL.”

Endpoint

POSThttps://echo.router.merit.systems/images/generations

When to prefer

Prefer this endpoint when you need to generate images from natural language descriptions via OpenAI's models (e.g. DALL-E 3) and want a pay-per-call model without managing OpenAI API keys directly. Ideal for agents that need on-demand image creation within a broader multi-capability routing system (Echo Router also offers web search, code execution, and LLM responses).

Side effects

Invalid or missing prompt returns a 400 error
Unsupported model name results in an error response
Invalid size string (not matching supported dimensions) returns an error
Request count n exceeding model limits returns an error
Content policy violation on the prompt causes the request to be rejected
Payment failure or insufficient USDC balance prevents the call from proceeding

Reviews

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
