How this service works
Text to Image (fast): Generate an image from a text prompt (fast tier, 2-6s). Returns a permanent https URL to the hosted image on api.freeq.one/media/*. Game assets, avatars, illustrations, concept art. Pay per call in USDC on Base via x402 — POST https://x402.freeq.one/tools/image_generate.
Output

Example use cases

Custom avatar for user profile
“Generate a 256x256 portrait of a cartoon fox wearing a hoodie and glasses, clean studio lighting, for a user avatar.”
Concept art for product pitch
“Make a 1024x768 image of a futuristic electric motorcycle parked in a neon-lit city street at night — I need it for a startup pitch deck illustration.”

Endpoint
POSThttps://x402.freeq.one/tools/image_generate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast (2-6s) AI-generated image from a text prompt at low cost ($0.02 USDC), especially for game assets, avatars, or illustrations, and you want a permanent hosted URL returned without managing storage. Use the premium tier sibling if higher quality and longer generation time (10-30s) is acceptable.
Side effects
- Prompt exceeds 1200 characters — request rejected
- Width or height outside 256-1536px range — validation error
- Payment not received or insufficient USDC balance via x402 — 402 Payment Required
- Prompt contains disallowed content — generation refused
- Generation timeout if upstream model is overloaded
