How to Generate AI Videos with Bitcoin Lightning
Text-to-video and image-to-video. No signup. No subscription. Just a prompt and a Lightning wallet.
For Humans
Use the web UI — no setup required.
AI video platforms charge $12–76/month and require an account before you can generate a single clip. Sats4AI skips all of that. Write a prompt or upload an image, pay a Lightning invoice, and download your video. HD quality, up to 15 seconds, no data stored about you.
Social media content
Generate short video clips for Instagram Reels, TikTok, or X without a subscription. Pay per clip — perfect for occasional or experimental content.
Bring still images to life
Have a photo or AI-generated image you want to animate? Use image-to-video to add natural motion while preserving the original composition.
Product and concept demos
Visualize a product, an architectural concept, or an idea before investing in production. Generate a rough clip in minutes for under $2.
Narrated explainers
Combine with text-to-speech to add a voiceover — generate the audio and video separately, then combine them in any editor.
Two Ways to Generate
Text-to-Video
Kling v3Describe the video you want in plain text. Supports 3–15 second clips, HD/1080p output, and optional AI-generated audio.
Try Text-to-Video →Image-to-Video
AnimateUpload a still image and describe the motion you want. The model preserves your image's style and composition while adding natural movement.
Try Image-to-Video →For Agents
Integrate via L402, MCP, or OpenClaw — no account, no API key.
Both video endpoints support L402 authentication: your agent sends the prompt or image, pays a Lightning invoice, and receives the video URL. No API key to store, no billing dashboard to monitor. Cost is per second of output — predictable and metered.
Automated video content pipelines
An agent generates images with the image service, then passes each one to image-to-video for animation — fully automated visual content at scale.
Product video catalogs
Feed product images into the image-to-video API to generate short motion clips for each SKU — no video team, no studio, billed per video.
On-demand campaign assets
A marketing agent generates video variations from different prompts and routes the best one to a delivery pipeline — no human approval needed for routine asset generation.
Multi-step media chains
AI chat drafts the prompt, image generation creates the frame, image-to-video animates it, and TTS adds narration — all in one pipeline, each step paid independently via Lightning.
L402 Authentication Flow
Send the request without auth
POST your prompt (and image for image-to-video) to the endpoint. The server responds with HTTP 402 + a Lightning invoice in the WWW-Authenticate header.
Pay the Lightning invoice
Your agent pays the invoice using a Lightning wallet or library. Save the preimage from the payment result.
Resend with the preimage
Repeat the identical request, adding an Authorization: L402 <macaroon>:<preimage> header. The server validates and returns the video URL once generation completes.
