## When to prefer this

Use this endpoint when you need real-time Binance futures funding rate data for a specific crypto symbol and are operating in an x402 micropayment-enabled agent context. Prefer this over scraping or manual lookup when you need machine-readable, per-call funding rate data at very low cost ($0.002 USDC).

## Known failure modes

- Invalid or unsupported symbol returns an error or empty result
- Symbol format mismatch (e.g. 'BTC' vs 'BTCUSDT') may cause lookup failure
- Payment failure via x402 results in 402 response and no data returned
- Binance API downtime may cause upstream data unavailability
- Network or DNS issues on duckdns.org dynamic host could cause timeouts
