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 refined/denoised image result, cached per payment hash so retries after paying don't incur an additional charge.

Example use cases

Example prompt

“Can you refine image ID 'img_abc123' to make it look more like a golden-hour sunset landscape, with a denoise level of 0.4?”

Technical details

Endpoint

POSThttps://x402.wallace.us/x402/image-refine?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to refine or denoise an existing image (referenced by image_id) using a guiding text prompt, and you are operating in a Lightning/x402 micropayment environment. Prefer this over generic image generation endpoints when you already have a source image and want to improve or transform it rather than generate from scratch.

Side effects

HTTP 402 returned with Lightning invoice if payment not yet made — must pay invoice and retry with X-Payment-Hash header
Invalid or missing image_id returns an error
Denoise value out of 0-1 range may be rejected or clamped
Payment hash not recognized if invoice expired before payment
Network timeout on inference backend
