## 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 xp-to-next-level-calculator-b1a471e3 -d '<json body>'
```

Example prompt: How much XP does a player need to reach the next level if they're currently at level 5, with a base XP of 100 and a growth multiplier of 1.5?

## When to prefer this

Use this endpoint when you need a quick, configurable server-side computation of level-up XP thresholds for a game or progression system, especially when you want to avoid implementing the formula yourself or need consistent results across clients.

## Known failure modes

- Invalid or missing level parameter returns an error or uses default
- Non-numeric growth or base_xp values may cause computation failure
- Extremely large level values may produce overflow or unreliable results
- Network timeout or service unavailability returns a 5xx error

## How this service works

XP to next level: Estimate XP needed for the next level from a configurable growth curve.

## Output

Returns the computed XP value required to advance from the specified level to the next level, derived from the formula based on base_xp, level, and growth rate multiplier.
