## 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 lp-gp-waterfall-distribution-calculator-7248e38e -d '<json body>'
```

Example prompt: Run a waterfall distribution for my real estate fund: we have $5M in capital contributions, an 8% preferred return (ACT/365), a 20% GP catch-up, and a 3-tier promote structure with IRR hurdles at 10%, 15%, and 20% — here are the cash flows across 4 periods. Can you calculate how much goes to the LP vs GP at each stage?

## When to prefer this

Use this endpoint when you need penny-accurate LP/GP waterfall calculations for private equity or real estate funds, especially when modeling multiple distribution periods, tiered promotes with IRR or MOIC hurdles, and GP catch-up provisions. It is ACT/365 day count compliant matching Excel behavior, making it ideal for reconciling fund models. Prefer this over spreadsheet-based tools when you need programmatic, auditable waterfall outputs in an automated workflow.

## Known failure modes

- Missing or malformed cash flow data returns 400 validation error
- Invalid hurdle type (not IRR or MOIC) returns 400
- More than 5 promote tiers specified returns 400
- Payment of $3 USDC not received returns 402 payment required
- Periods with inconsistent date formats may cause day count errors
- Negative capital contributions or invalid percentages return 422

## How this service works

LP/GP waterfall distribution across preferred return, GP catch-up, and multiple promote tiers. Returns LP and GP splits, IRR, MOIC, and per-period cash flow allocation.

## Output

A period-by-period breakdown of cash distributions showing: return of capital amounts, preferred return accruals and payments, GP catch-up amounts, and allocations across up to 5 promote tiers — all computed to penny accuracy using Python Decimal with ACT/365 day count convention matching Excel behavior.
