How this service works
Independent pay-per-image text-to-image gateway. Fixed price per image, USDC on Base.
Output
A JSON object containing a 'data' array with one entry per generated image. Each entry includes a 'b64_json' field with the base64-encoded PNG image and a 'revised_prompt' string showing how the model interpreted or refined the original prompt. The response also includes a 'created' Unix timestamp indicating when the image was generated.
Example use cases

Social media visual asset
