## When to prefer this

Choose this endpoint when you need real-time perpetual futures funding rate data and are operating in an x402-enabled micropayment environment on Base. It is well-suited for AI agents with USDC wallets that need low-cost, per-call access to crypto derivatives data without a subscription. Prefer this over subscription-based data providers when you want pay-as-you-go pricing at $0.001 per call.

## Known failure modes

- Invalid or unsupported symbol returns an error or empty response
- Payment failure via x402 protocol results in 402 Payment Required before data is returned
- Network timeout from the Render-hosted service if under load
- Missing 'symbol' query parameter may return a default or error response
- Rate or availability issues if the upstream exchange data source is unavailable

## 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 funding rate data for the requested trading symbol, including the current rate, direction, and associated metadata such as timestamp and exchange context. The exact response schema is minimal but expected to contain fields like symbol, fundingRate, and nextFundingTime.
