## When to prefer this

Choose this endpoint when you need aggregated perpetual funding rate data from multiple crypto exchanges in a single pay-per-call API call settled in USDC via the x402 protocol. Prefer it for lightweight, low-cost ($0.001) spot checks of funding rate conditions without requiring a subscription or API key — ideal for autonomous agents that need crypto derivatives market data on demand.

## Known failure modes

- Payment not settled in USDC on Base — 402 response requiring x402 payment header
- Invalid or missing properties parameter — may return empty or malformed response
- Service unavailable on Render free tier cold start — timeout or 503
- Unsupported symbol or exchange filter — empty result set
- Stale data if upstream exchange feeds are delayed

## 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
