Example prompt: What's the current perpetual funding rate for DeFi perp markets via Mangrove Developer? I want to check whether funding is positive or negative before entering a position.

## When to prefer this

Use this endpoint when you need real-time or current DeFi perpetual futures funding rate data and are operating within the Mangrove Developer ecosystem. Prefer this over generic market data APIs when you need funding-rate-specific DeFi perp data accessible via x402 micropayment.

## Known failure modes

- Missing or malformed properties parameter returns a 400 error
- No matching market found returns empty or null funding data
- Payment not completed (402) if x402 micropayment is not attached
- Rate limiting or quota exceeded returns 429
- Stale data if underlying DeFi data source is delayed
