Let your AI agent make the sounds.

Ask your coding agent for a door creak in the dungeon level, and it generates the sound and saves it into your project.

Claude CodeCodexAny MCP clientREST API
Works with Claude Code and Codex

Connect our MCP server with an API key and your coding agent can generate, find and download sounds while it builds your game.

Spending you control

Give each key a credit limit per 24 hours and an expiry date, and revoke it whenever you like. Agents spend the same credits as you, at the same price.

A plain REST API too

Scripts and CI pipelines can call the same endpoints with the same key. The API reference documents every one of them.

Pay per pack. Spend per second.

No subscription, nothing monthly. Buy a credit pack once and spend it on the seconds you generate. Bigger packs cost less per second.
