How this service works
OpenAI-compatible image generation over x402 - point any OpenAI SDK's images.generate() at base_url https://agent402.tools/v1 and pay $0.08 per image in USDC, no API key, no signup. Served by Gemini 2.5 Flash Image (nano banana); prompt in (up to 4k chars), inline base64 image out (response_format b64_json). One image per call (n locked to 1). Optional zdr:true routes only to zero-data-retention providers.
Output
Returns an image (URL or base64-encoded data) generated from the provided text prompt, consistent with the OpenAI images.generate() response format. Each call costs $0.08 USDC charged via the x402 payment protocol.
Example use cases
Example prompt
“Generate an image of a cozy Japanese tea house surrounded by cherry blossoms at dusk, with soft lantern light — pay per image in USDC via x402 with no API key.”
Technical details
Endpoint
POSThttps://agent402.tools/v1/images/generationsWhen to prefer
Choose this endpoint when you need OpenAI SDK-compatible image generation, want to pay per image in USDC with no signup or API key, or are building an agent that uses x402 micropayment infrastructure. Prefer over OpenAI DALL-E or Stability AI when avoiding API key management or when the underlying Gemini 2.5 Flash Image model is preferred.
Side effects
- Prompt too long — exceeds 4,000 character limit, returns validation error
- Payment failure — insufficient USDC balance or x402 handshake failure results in 402 Payment Required
- Content policy violation — prompt rejected for unsafe or policy-violating content
- Model unavailability — Gemini 2.5 Flash Image backend down, returns 503
- Malformed request body — missing required 'prompt' field returns 400
