Example prompt: What are the current DeFi yield rates across major protocols right now? I want to see APY data so I can compare lending and liquidity opportunities.

## When to prefer this

Choose this endpoint when you need pay-per-call DeFi yield rate data settled via x402 USDC micropayments on Base, particularly when integrating into autonomous agent workflows that require real-time APY comparisons across DeFi protocols without a subscription commitment.

## Known failure modes

- Payment not settled — x402 micropayment of $0.001 USDC not confirmed, returns 402 Payment Required
- Invalid or missing properties parameter — returns error or empty result
- Service temporarily unavailable on Render.com free-tier hosting — returns 503
- Data freshness issues — yield rates may be stale if upstream data sources are delayed
- Empty response if no yield data matches the query filter

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

Returns current yield rate data for DeFi protocols, likely including APY/APR figures, protocol names, and asset-specific yield metrics. Response format is minimal per the schema but expected to contain yield rate snapshots.
