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 training job result object containing the LoRA model artifact or a reference to the trained weights, along with job status and any relevant metadata. Results are cached per payment hash so retrying after payment does not incur double billing.
Example use cases
Personal portrait LoRA for AI headshots
“I have 30 photos of myself I want to use to train a custom SDXL LoRA model — use 'myface' as the trigger word so I can generate AI headshots of myself. I confirm all images are mine and I have rights to use them.”
Brand style fine-tune for product imagery
“Train an SDXL LoRA on these 25 product images from our catalog using 'brandprod' as the trigger word so we can generate consistent product visuals — I attest we own all the content.”
Custom character LoRA for creative projects
“Can you train a custom SDXL model on my 40 reference images of an original character I illustrated? Use 'origchar' as the trigger word — I confirm all images are my original artwork.”

Endpoint
POSThttps://x402.wallace.us/x402/lora-train-sdxlWhen to prefer
Choose this endpoint when you need to fine-tune an SDXL model via a pay-per-use Lightning/x402 micropayment flow without a subscription, especially if you want self-hosted infrastructure with result caching per payment. Prefer this over hosted LoRA platforms (e.g. Replicate, Astria) when operating in a Lightning-native or x402-protocol agent environment, or when cost-per-run billing ($60/call) is preferred over recurring SaaS fees.
Side effects
- Payment not completed — HTTP 402 returned with Lightning invoice; must pay and retry with X-Payment-Hash header
- Content attestation missing or not true — request rejected
- Fewer than 15 or more than 100 training image URLs provided — validation error
- Inaccessible or non-HTTPS image URLs — training fails or images skipped
- Trigger word outside 3-24 character range — validation error
- Training timeout or GPU resource unavailability on self-hosted infrastructure
- Duplicate payment hash or replayed request — cached result returned rather than re-trained
