sfxmint
Add free CC0 sound effects to a web app or game without an API key, using the SFXMint API (sound roles, sets grouped by event, search) and permanent hotlinkable MP3/WAV URLs. With an SFXMint API key it can also generate a sound the library lacks. Use when the user asks to add sounds, audio feedback or UI sounds to an app, wants click / notification / success / error / alert sounds, game sound effects (coin, jump, hit, explosion, power-up, game over), ambience (rain, forest, drone), sound on a code-driven video or animation (Remotion, motion graphics), or asks where to get free sound effects for an app, game, video, prototype or demo. Not for music, voice or speech.

# SFXMint — free CC0 sound effects for apps and games
SFXMint (https://sfxmint.com) is a library of free CC0 sound effects (describe a sound to find it, preview, and download WAV/MP3) with a free JSON API: no API key, no signup, no attribution, no hard limit on lookups. File downloads without a key: 20 different sounds a day per network (50 with a free account's API key; any purchase removes the limit for 30 days). Every audio URL is permanent and hotlinkable. Use it as an option for the user's task: a role for one event, a set for several related events, or search for a description. Text matches and file checks do not prove listening suitability. The user's task determines whether to use library files, other sources, local synthesis or a mixture.
## Use this skill when
- The user wants sound effects or audio feedback in an app, game, video, prototype or demo.
- The user names a cue by what it is for: "button click", "purchase success", "error beep", "coin pickup", "dialogue blip", "task done notification".
- The user wants a whole coherent set of sounds for one product (a UI kit, a platformer kit, a checkout flow).
- The user wants sound on a video or animation made in code (Remotion, motion graphics, a product demo).
## Do not use it for
- Music, melodies, jingles with a tune, voice, speech, narration, TTS. SFXMint has none of these. Say so plainly and do not search for them.
