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 image. Each entry includes b64_json (a base64-encoded PNG of the generated image) and a revised_prompt string (the model's reinterpretation of the input prompt). The top-level object also includes a created Unix timestamp.
Example use cases
AI illustration for blog post
“Create an image of a futuristic cityscape at night with neon lights reflecting on wet streets — I want a moody, cinematic feel for an article header.”
Custom product concept visualization
“Generate an image of a sleek, matte-black coffee thermos on a wooden desk with morning sunlight streaming in — make it look like a high-end product photo.”
Fantasy character portrait
“Can you create an image of an elven archer standing in an enchanted forest, wearing ornate silver armor with glowing runes, in a detailed fantasy art style?”

Endpoint
POSThttps://agent402.mufu.workers.dev/v1/gpt-image-2.5-sunburst/images/generations?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need one-off or low-volume AI image generation without committing to a subscription, especially in crypto-native or agent workflows that already use USDC on Base for payments. It is particularly well-suited for AI agents that need to autonomously pay per image using the x402 protocol. Prefer this over subscription-based image APIs when cost predictability per image ($0.08 flat) is important, or when your infrastructure is already integrated with Base chain payments.
Side effects
- Payment failure: insufficient USDC balance on Base network returns 402 Payment Required
- Invalid or empty prompt returns 400 Bad Request
- Model unavailability or upstream API error returns 500 or 503
- Rate limiting or quota exceeded returns 429
- Malformed request body returns 400 with validation error
