## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability evplus-funding-server-onrender-com-25996109 -d '<json body>'
```

Example prompt: Give me bias-optimized funding rate arbitrage positions for a slightly bullish market outlook — use a bias score of 0.7.

## When to prefer this

Choose this endpoint when you have a directional market view and want funding rate arbitrage positions that are specifically filtered or ranked to align with that bias, as opposed to bias-agnostic arb signals. Ideal when your strategy requires matching arb positions to a bullish, bearish, or neutral stance rather than taking all opportunities indiscriminately.

## Known failure modes

- Invalid bias score outside 0.0–1.0 range returns validation error
- Service unavailable on Render cold start causing timeout
- Missing required bias parameter returns 400 bad request
- No arbitrage opportunities available for given bias returns empty result set
- Payment failure via x402 protocol returns 402 Payment Required

## Output
