## When to prefer this

Choose this endpoint when you need real-time DeFi market sentiment derived from trader positioning (long vs short ratios) for crypto assets, especially in automated trading agents or sentiment dashboards. Prefer this over generic market data APIs when you want AI-curated DeFi intelligence accessible via micropayment without API key management.

## Known failure modes

- Unsupported or unrecognized asset symbol returns an error or empty result
- x402 payment failure if USDC balance is insufficient or Base network is congested
- Stale data if upstream futures data provider is delayed
- Rate limiting or payment rejection if too many rapid requests are made

## How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

## Output

Returns the current long/short ratio for the requested crypto asset, showing the proportion of traders holding long versus short positions, which serves as a market sentiment and directional bias indicator.
