Endpoint

When to prefer

Choose this endpoint when you need AI-generated images from text prompts with flexible aspect ratios and model options (including GPT-Image-2 or Nano Banana Pro), especially for memes, logos, posters, or photorealistic visuals. Also choose it when you need to edit or remix an existing image by URL. Prefer this over alternatives when operating in an x402 micropayment context and need a hosted URL output.

Side effects

Prompt too short (under 10 characters) returns validation error
Invalid aspect_ratio value returns error
Invalid model name returns error
Image URL provided is not publicly accessible, causing edit failure
Generation failure returns status 'failed' with error message
Payment not completed results in 402 response before generation begins
