## 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 api-quantoracle-dev-15a20c27 -d '<json body>'
```

Example prompt: What's the optimal rebalancing threshold for my crypto portfolio with target weights of 50% BTC, 30% ETH, and 20% SOL, assuming transaction fees of 0.25% per trade and a monthly rebalancing review?

## When to prefer this

Use this endpoint when you need a mathematically grounded, cost-aware rebalancing threshold for a crypto portfolio rather than using a fixed arbitrary percentage. It is especially useful when transaction fees vary and you want to avoid over-trading. Prefer this over generic portfolio tools when working specifically with crypto assets and needing a quantitative trigger level.

## Known failure modes

- Invalid or missing portfolio weights that don't sum to 100% — returns 400 validation error
- Negative or zero transaction cost values — returns 400 bad request
- Unsupported asset tickers or unrecognized crypto symbols — returns 422 unprocessable entity
- Malformed request body or missing required fields — returns 400 with field-level error details
- Service unavailability or timeout — returns 503 or 504

## How this service works

QuantOracle: crypto/rebalance-threshold

## Output

Returns a computed rebalancing threshold — the percentage drift from target allocations that should trigger a rebalance — along with cost-adjusted trigger bands and a recommended tolerance range that balances tracking error against transaction costs.
