Endpoint
GEThttps://api.x-402.online/v1/image?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast (≈4 second), pay-per-call text-to-image generation with no account setup, API key, or subscription — ideal for agents that generate images infrequently or on-demand and want to pay only per use in USDC via the x402 protocol. Prefer this over subscription-based image APIs when cost predictability per call and zero onboarding friction matter.
Side effects
- Empty or missing prompt returns an error
- Payment not received or insufficient USDC results in 402 Payment Required
- Model timeout if generation exceeds expected latency window
- Invalid HTTP method (non-GET) returns 405 Method Not Allowed
- Prompt content policy violation may result in refusal or error
