How this service works
Self-hosted personal-assistant paid tools via Lightning. Uses x402-shaped protocol (L402 lineage): HTTP 402 with a Lightning invoice in the response body + WWW-Authenticate header, retry with X-Payment-Hash: <hex> once paid. Results cached per payment_hash so legitimate retries don't cost twice.
Output
Returns a JSON object containing the upscaled image result (likely a URL or image data), cached per payment_hash so retrying with the same payment doesn't charge again.
Example use cases
Example prompt
“Can you upscale my image (ID: abc123) to 4x using the esrgan mode? I want the sharpest result possible.”
Technical details
Endpoint
POSThttps://x402.wallace.us/x402/image-upscaleWhen to prefer
Use this endpoint when you need AI-powered image super-resolution (ESRGAN or hires_fix) on demand, pay-per-use via Lightning/x402 without a subscription. Ideal for agents that need occasional image upscaling at low cost ($0.30 USDC per call) without committing to a SaaS plan.
Side effects
- HTTP 402 returned with Lightning invoice if payment not yet made — must pay invoice and retry with X-Payment-Hash header
- Invalid image_id returns an error if the image cannot be found
- Unsupported factor value (anything other than 2 or 4) may cause a bad request error
- Invalid mode string (not esrgan or hires_fix) may cause processing failure
- Network timeout if upscaling is slow for large images
- Payment hash not recognized or already expired
