## When to prefer this

Choose this endpoint when you need arbitrage positions filtered or ranked by directional market bias (bearish/neutral/bullish), as opposed to raw best-rate funding arbitrage. Prefer this over the sibling funding-rate endpoint when the user has a specific market directional view they want to express in their arbitrage strategy.

## Known failure modes

- Invalid bias value outside 0.0–1.0 range returns a validation error
- No arbitrage opportunities matching the specified bias returns an empty result set
- Payment of 0.24 USDC not processed via x402 results in 402 Payment Required
- Downstream market data unavailable causes 503 or timeout
- Malformed POST body returns 400 Bad Request
