## 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 royalty-split-calculator-9adb2ecc -d '<json body>'
```

Example prompt: Split a $12.50 royalty pool between three contributors: 0xABC...001 gets 50%, 0xDEF...002 gets 30%, and 0xGHI...003 gets 20%, with exact sub-cent precision and no rounding drift.

## When to prefer this

Prefer this endpoint when you need deterministic, drift-free splitting of a micropayment or royalty pool across multiple wallet addresses or DIDs, especially when cent-level precision matters and floating-point arithmetic errors would cause imbalance. Ideal for automated royalty workflows, DAO disbursements, or any multi-contributor payout where the split percentages are known upfront.

## Known failure modes

- Splits do not sum to 1.0 — validation error returned requiring percentages to total exactly 1.0
- Individual percentage below minimum 0.0001 — rejected with validation error
- total_amount below minimum 0.0001 — request rejected
- Malformed payee wallet address or DID — may cause downstream errors
- More splits than the system can accommodate — potential payload rejection

## How this service works

Splits micropayment batches across multiple contributor addresses with sub-cent rounding and zero floating-point drift.

## Output

Returns a breakdown of each payee's calculated allocation amount in USD, derived from their percentage share of the total pool, computed with sub-cent rounding logic that ensures the sum of all allocations equals the total_amount exactly without floating-point drift.
