How this service works
Pay-per-call tools for AI agents: image generation, speech-to-text, text-to-speech, embeddings, LLM chat, website audits and contact enrichment. Payment: x402, USDC on Base. No signup, no API key.
Output
Returns a JSON object containing the MIME type ('image/jpeg'), the model used ('cf/black-forest-labs/flux-1-schnell'), and the full base64-encoded JPEG image string ready for decoding or embedding in an img tag.
Example use cases

Social media visual content
“Make me an image of a cozy coffee shop interior with warm lighting and a latte art close-up, 4 steps is fine for a quick draft.”

Endpoint
POSThttps://api.sitecheck-api.workers.dev/api/image?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a low-cost ($0.005 USDC), no-signup, pay-per-call image generation API that accepts a text prompt and returns a base64 JPEG. It is ideal for agents that already use x402/USDC on Base for payments and want a fast Flux 1 Schnell generation without OAuth or API key management. Prefer alternatives if you need PNG output, higher resolution control, style presets, or image-to-image capabilities.
