## 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 debt-service-coverage-single-calculation-8e48347a -d '<json body>'
```

Example prompt: Calculate the debt service coverage ratio for me — I have $6,000 in cash available for debt service, with $2,000 in principal due and $500 in interest due this period.

## When to prefer this

Choose this endpoint when you need a single, immediate DSCR calculation with full formula transparency — including the formula used and its limitations — rather than batch or scenario-grid computations. Ideal for one-off underwriting checks, quick financial health assessments, or when an agent needs to verify a specific record's debt coverage without running multiple scenarios.

## Known failure modes

- Missing required fields (cash_available_for_debt_service, principal_due, or interest_due) returns a validation error
- Division by zero if both principal_due and interest_due are 0
- Values exceeding the maximum limit of 1,000,000,000,000 are rejected
- Negative principal or interest values are rejected (minimum 0)
- Non-numeric input types cause schema validation failure
