## When to prefer this

Use this endpoint when you need a single specific CC0-licensed music track (signal-bloom) with a direct download URL and are comfortable paying $0.05 USDC per call via x402 on Base mainnet. Prefer this over scraping music sites or using subscription-based services when you need per-call micropayment billing and guaranteed CC0 licensing with no attribution requirements.
