# Product recipe: Video from a prompt (AgentGid)

For short videos made from a text prompt: script, voiceover, music, footage or generated clips, rendered in code.

Parts were picked from AgentGid's catalog by rules: free tier, official MCP server, use in public projects built with AI agents, downloads, price. Prices are list prices from the official pages (see each card for the check date); confirm before you commit.

## What it costs

- If you outgrow the free tiers, the lowest paid plans of the first picks are ElevenLabs Music API $6, Cloudinary $99 (together about $105/month); usage beyond a plan's credits is billed on top.
- Billed by usage (grows with traffic): Runway API, Deepgram.

## Before you ship
- Check each generator's terms for commercial use and for what you may publish.
- Keep API keys on the server, never in the client; set spending limits where the provider offers them.
- Read each service's terms for your use (data retention, commercial use, rate limits).
- Log model calls (traces) and test with your own real inputs before launch.
