Example prompt: Can you pull the current derivatives positioning data for BTC-PERP so I can see how the market is leaning right now?

## When to prefer this

Use this endpoint when you need lightweight, per-call derivatives positioning or funding rate data for major crypto assets (BTC, ETH, SOL) and are operating in an x402 micropayment-enabled agent context willing to pay $0.039 USDC per query. Best suited for agents that need on-demand spot checks rather than streaming or bulk historical data feeds.

## Known failure modes

- Missing or invalid 'symbol' query parameter returns an error or empty result
- Unsupported ticker symbol not recognized by the server
- Payment not completed or x402 micropayment rejected — request not fulfilled
- Rate limiting or server unavailability returns a non-200 response
- OFAC-screened addresses blocked from access

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

A JSON object with a 'success' boolean and a 'result' object containing derivatives positioning data (such as funding rates, open interest, or positioning metrics) for the requested asset symbol. The exact fields within 'result' depend on the server-side data available for the queried symbol.
