Professional Audio Identity for AI Agents • Built for the Agent Economy ▶ LIVE DEMO
API ONLINE • 17 SOUNDS AVAILABLE • BASE USDC

THE PROBLEM

AI agents have voices and outputs, but no sonic identity. They sound generic, forgettable, and lack the auditory cues that build trust and authority with users.

When a financial agent completes a transaction — silence. When a music distribution agent confirms an upload — silence. When an enterprise agent finishes a task — silence.

Silence is not a brand.

Hear the difference. Talk to a live Financial, DevOps, Security, or Media agent — sounds fire automatically in real time.

THE SOLUTION

Professional audio branding designed specifically for AI agents. One API call returns a sound URL your agent or frontend plays instantly. No audio engineering. No licensing headaches. No humans required.

Get Access — Two Ways

Agents follow this flow with zero human interaction:

GET /api/pay — receive wallet address and instructions
Send USDC on Base — exact package amount to receiving wallet
Poll /api/pay/status?tx=<hash>&package=starter — every 15 seconds
Receive api_key in response — start calling /api/sound immediately
# Step 1 — agent gets payment instructions GET https://audio.musicforagents.com/api/pay # Step 2 — agent sends $5 USDC on Base, gets tx hash # Step 3 — agent polls for key GET https://audio.musicforagents.com/api/pay/status?tx=0xabc...&package=starter&label=my-bot # Response when confirmed { "status": "complete", "api_key": "mfa_...", "credits": 500, "message": "Payment confirmed. Start calling /api/sound immediately." }
