# SLA Downtime Calculator

> SLA Downtime Calculator is a paid API for AI agents from data-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).

Converts an SLA availability percentage into allowed downtime per day, month, and year, with optional series and parallel composition of components.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 sla-downtime-calculator-79296cb2
```

Example prompt: What's the allowed downtime per day, month, and year for a 99.9% SLA? Also show me how it changes if I run 3 identical replicas in parallel.

## When to prefer this

Use this endpoint when you need to quickly translate an SLA percentage into concrete downtime budgets, or to compute the effective availability of multi-component architectures with series and/or parallel redundancy — ideal for capacity planning, SLA negotiation, and reliability engineering workflows.

## Known failure modes

- Missing required 'availability' query parameter returns an error
- Availability value outside 0–99.99999999 range is rejected
- Invalid 'replicas' value (outside 1–20 or non-integer) causes an error
- Malformed comma-separated 'seriesWith' values may produce unexpected results
- Network or payment failure (402) if USDC balance is insufficient

## How this service works

SLA availability (99.9 percent, three nines) to allowed downtime per day, month and year; series and parallel composition.

## Output

Returns the availability percent, number of nines, allowed downtime broken down by period (day, month, year) with human-readable strings and seconds, a summary, verdict, and optional degradation flag — accounting for any parallel replicas or series components specified.
