## When to prefer this

Use this endpoint when you need a zero-parameter, real-time DAI/USD spot price — ideal for DeFi dashboards, stablecoin monitoring, arbitrage checks, or any workflow needing the current DAI peg status without building exchange integration. Prefer over generic crypto APIs when you need a simple, paid, low-latency lookup with a clean JSON schema.

## Known failure modes

- Upstream price feed unavailable — may return stale or error response
- Payment failure (x402) if USDC balance is insufficient — returns 402 Payment Required
- Rate limiting if called too rapidly
- Price source outage returns partial or null price field
