Callers send a POST request with a text prompt in the `input` field and, after satisfying the x402 payment challenge (paid in USDC on Base), receive a generated image or image-related response from the agent.\n\nThe endpoint follows the x402 protocol: an unauthenticated request returns HTTP 402 with a JSON challenge specifying the payment asset (USDC at `0x8335…2913` on Base), the maximum amount required (0.10 USDC, given 6-decimal precision), the payee address, and a timeout of up to 1200 seconds. Once the `X-PAYMENT` header is supplied with a valid payment proof, the agent processes the prompt and returns a string response.\n\nDocumentation beyond the x402 challenge itself is sparse. Questflow's public site focuses on its \"AI Clone\" trading-agent platform rather than this specific image-generation endpoint. No OpenAPI spec, usage examples, rate limits, or detailed output format documentation were found. The output schema in the challenge indicates a simple `{\"response\": \"...\"}` JSON object, but it is unclear whether the response contains a URL to the generated image, base64-encoded data, or something else.","tags":[],"capabilities":["image-generation","openai-integration","x402-payment","usdc-base","text-to-image","agent-endpoint"],"categories":["vision","llm"],"synonyms":["OpenAI image
