## 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 x402toll-debt-payoff-plan-report-avalanche-vs-snowball-2ded7b25 -d '<json body>'
```

Example prompt: Run a full avalanche vs snowball debt payoff simulation for my three debts: a Visa with $8,400 balance at 22.9% APR and $180 minimum, a car loan with $12,000 at 6.5% APR and $240 minimum, and a personal loan with $3,200 at 14% APR and $95 minimum — I can put an extra $200 a month toward debt. Tell me the payoff order, debt-free month, total interest for each strategy, and the exact gap between them.

## When to prefer this

Use this endpoint when a user wants a detailed, strategy-level debt payoff comparison between avalanche and snowball methods with month-by-month rollover modeling — not just a simple payoff calculator. Ideal when the user has multiple debts (up to 8) and wants to see the concrete interest savings and time difference between strategies, including the effect of extra monthly payments.

## Known failure modes

- Missing required fields (balance, apr, minPayment) on any debt object returns a validation error
- More than 8 debts in the array exceeds maxItems limit
- Minimum payments that don't cover interest may result in infinite payoff horizon or error
- Non-numeric values for financial fields cause schema validation failure
- Extra monthly amount below zero may be rejected

## How this service works

Full debt-payoff report: avalanche vs snowball simulated month-by-month with debt rollover — payoff order, debt-free month, total interest, and the exact gap between strategies.

## Output

A full debt payoff report with month-by-month simulation for both avalanche (highest-APR-first) and snowball (lowest-balance-first) strategies, including: payoff order of each debt, the month and year you become debt-free under each strategy, total interest paid under each strategy, the exact dollar difference between strategies, and debt rollover amounts as each debt is eliminated.
