## 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 agent-rest-stop-budget-split-4d598bf7 -d '<json body>'
```

Example prompt: Split a $300 budget across three items — marketing at weight 0.5, engineering at weight 0.3, and design at weight 0.2 — without letting any single item exceed its cap.

## When to prefer this

Use this endpoint when you need to programmatically divide a fixed USD budget across multiple named items according to relative weights, especially when you want the guarantee that no individual allocation exceeds a cap. Prefer this over manual calculation when the number of items or weight values may vary dynamically in an agent workflow.

## Known failure modes

- Weights that sum to zero or are malformed may cause division errors or unexpected results
- Non-numeric or missing budget_usd value will likely cause a parsing or validation failure
- Malformed items string (wrong delimiter or format) may result in incorrect splits or errors
- Weights summing to more or less than expected may cause proportional distortions
- API returns HTTP 402 if payment of $0.01 USDC is not provided

## How this service works

Splits a budget by weight without passing caps.

## Output

Returns the computed budget allocation for each input item, with amounts split proportionally by weight and constrained so no item exceeds its cap. Likely includes per-item dollar amounts that sum to or stay within the total budget_usd.
