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.

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

"api_key": "mfa_...",
