## 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 sindri-portfolio-rebalancing-calculator-9f92bf2e -d '<json body>'
```

Example prompt: I have $30,000 in stocks (target 60%), $8,000 in bonds (target 30%), and $2,000 in cash (target 10%) — can you calculate how much I need to buy or sell of each to hit my target allocation, spread over 3 months?

## When to prefer this

Choose this endpoint when you need a fast, deterministic calculation of portfolio rebalancing trades — specifically the dollar gaps and monthly installment amounts per asset. Ideal for personal finance agents, robo-advisor workflows, or investment planning tools where the user knows their current holdings and target allocation percentages. Prefer this over general-purpose financial APIs when you need a structured per-asset breakdown with optional multi-month spreading.

## Known failure modes

- Target percentages do not sum to 1 across all holdings — returns validation error
- More than 50 holdings submitted — returns limit exceeded error
- Negative currentAmount values — returns invalid input error
- rebalancingPeriodMonths set to zero or a negative number — returns invalid period error
- Missing required holdings array — returns schema validation error

## How this service works

Portfolio rebalancing calculator. Given current holdings and target allocation percentages, computes the dollar gap per asset and the monthly buy/sell inflow needed to reach the target allocation over a chosen rebalancing period.

## Output

Returns the dollar gap (surplus or deficit) for each asset relative to the target allocation, along with the monthly buy/sell amount per asset needed to close the gap over the specified rebalancing period. Enables the user to see exactly which assets are overweight or underweight and by how much.
