Example prompt: Can you look up the metadata for the Flathub app with ID org.videolan.VLC — I want to know its official name, summary, and license?

## When to prefer this

Use this endpoint when you need to retrieve structured metadata (name, summary, license) for a specific Linux Flatpak app by its Flathub app ID. Prefer this over scraping the Flathub website or using other software registries when the input is a known Flathub app ID.

## Known failure modes

- App ID not found on Flathub — returns empty result or error JSON
- Malformed app ID format — may return 400 or empty response
- Flathub upstream unavailable — may cause timeout or 5xx error
- Payment not processed — x402 payment required error
