How this service works
125 production APIs behind HTTP 402 micropayments. 87 LLMs, Kling V3 and Hailuo video generation, image generation, code execution, travel search, web scraping, TTS, and transaction simulation. Pay with USDC on Base, USDm on MegaETH, or USDC on Solana.
Output
Returns a generated image (likely as a URL or base64-encoded data) where the face from the reference image has been composited into the scene described by the prompt, rendered at the specified dimensions with identity preservation controlled by id_weight.
Example use cases
Professional headshot from casual photo
“I have a casual selfie of my colleague at https://example.com/colleague.jpg — can you generate a polished professional headshot of them in formal business attire with a clean studio background, 1024x1024, and make sure to preserve their face accurately?”
Fantasy character portrait from real face
“Take the face from https://example.com/myface.jpg and generate a fantasy warrior portrait with dramatic lighting and an armored backdrop, 1024x1024, avoiding blurriness or distorted features, with id_weight 1.3 to keep my likeness strong.”
Personalized marketing creative
“Swap the face from https://example.com/model.jpg into a vibrant lifestyle product photo — someone smiling outdoors in summer clothing — 1024x768, with soft natural lighting and no extra fingers or artifacts.”

Endpoint
POSThttps://x402engine.app/api/image/face-swap?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to place a specific real person's face into an AI-generated scene and require prompt-controlled scene description alongside identity preservation. It is distinct from simple background replacement or inpainting — it combines text-guided image generation with face identity transfer in one call. Prefer this over generic image generation when the output must preserve a recognizable likeness.
Side effects
- Reference image URL is inaccessible or returns 404 — face cannot be extracted
- No detectable face in the reference image — swap fails or returns distorted output
- Prompt conflicts with identity preservation causing uncanny or blended output
- Width or height outside 256-2048 range causes validation error
- Payment failure or insufficient USDC balance blocks the request with HTTP 402
- High id_weight combined with complex scene prompt may produce artifacts
