## When to prefer this

Choose this endpoint when you need a consolidated view of perpetual futures funding rates across multiple exchanges in a single API call, especially when paying with USDC on Base via x402 protocol fits your agent's payment infrastructure. Prefer this over exchange-specific APIs when cross-venue comparison is the goal and the $0.001 micro-payment cost model is acceptable.

## Known failure modes

- Empty or incomplete response if no properties parameters are specified
- Payment failure if USDC balance on Base is insufficient for the $0.001 per-call fee
- 502/503 errors if the Render.com hosted service is cold-starting or unavailable
- Stale data if upstream exchange APIs are throttled or unresponsive
- Schema mismatch — response schema is minimally documented so output shape may vary

## 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 aggregated perpetual futures funding rate data across multiple crypto exchanges, likely including per-exchange funding rates, annualized rates, and possibly asset-level summaries to allow comparison of funding costs and arbitrage opportunities.
