Questions
What do I send to sound effects from a description?
Send a prompt for the sound in one POST to https://api.percify.io/v3/playground/v1/run. You get a sound effect file.
What does it cost?
With Mirelo SFX 1.6 it is $0.25 each (10 credits each). The estimate call returns the exact price of your input before you run it, and a run that fails is refunded.
Which model should I use?
Budget: Mirelo SFX 1.6 ($0.25 each). Switching is one string in the request: the model id.
Can an AI agent do this for me?
Yes. Connect your agent to the MCP server at https://mcp.percify.io/mcp and ask for it in plain words. The agent calls the generate tool with the same model id and input shown on this page, and the call spends the same credits.
