Photoreal image + video generation and upscaling via fal.ai (pay-per-use, one API key, always-current models: Kling, Seedance, FLUX, nano-banana Pro, Topaz). Use for image-to-video ("animate this image", "turn this photo into a video"), photoreal video clips for websites/demos, hero video loops, upscaling images/video, or any gen-media need beyond simple local generation. Rewrites rough prompts into model-optimized ones, routes to the cheapest model that fits, saves outputs locally. NOT for…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# media-gen — fal.ai cost-router
One fal.ai key covers every current image/video model, pay-per-use — no
subscription, no monthly minimum. You prepay credit on fal.ai's dashboard and
each request draws down from it: **spend is real money — be surgical.**
## Auth
Read the key from the environment first; fall back to the hub's `.env` (the
`/jarvis-setup` page's Media section writes it there). The hub itself
resolves the same way the SessionStart hook does: `JARVIS_HUB` env var first,
else the pointer file at `~/.jarvis-hub-path` written by `/jarvis-setup`,
else `~/jarvis-hub`. Never hardcode a path to it and never echo/print/log the
value:
```bash
hub="${JARVIS_HUB:-$(cat ~/.jarvis-hub-path 2>/dev/null)}"
hub="${hub:-$HOME/jarvis-hub}"
FAL_KEY="${FAL_KEY:-$(grep '^FAL_KEY=' "$hub/.env" 2>/dev/null | cut -d= -f2-)}"
```
If `FAL_KEY` is still empty after that, stop and tell the user to add it via
`/jarvis-setup` — do not hunt for it elsewhere. Every request:
header `Authorization: Key $FAL_KEY`.
## Cost discipline (the point of this skill)
- **Images are cheap** (fractions of a cent). Iterate freely.

How to install
mdr add mancerayder42/jarvis-os/media-gen@sha256:d336677acb5111fdThe line at the top of this page pins the label git:20260827.f197bb5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
