# Total XP by Level Calculator

> Total XP by Level Calculator is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-03).

Computes the cumulative experience points required to reach a target level by summing a geometric XP curve defined by a base XP value and growth multiplier.

## 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 total-xp-by-level-calculator-305c72e8 -d '<json body>'
```

Example prompt: Calculate the total XP needed to reach level 20 using a base XP of 100 and a growth rate of 1.5 per level — so I can tune my RPG's progression curve.

## When to prefer this

Choose this endpoint when you need to compute cumulative (total) XP across all levels up to a target, rather than XP required for a single level-up step. Ideal for game designers tuning progression systems, balancing reward economies, or displaying total XP milestones to players. Prefer this over a per-level XP calculator when the question is 'how much total XP to reach level N' rather than 'how much XP to go from level N to N+1'.

## Known failure modes

- Invalid or missing level value may return an error or fall back to default
- Negative or zero growth rate may produce undefined mathematical results
- Non-integer or extremely large level values may cause computation errors or timeouts
- Missing required fields may default silently, returning results that don't match the user's intended parameters

## How this service works

Total XP by level: Sum a geometric XP curve to estimate total XP through a target level.

## Output

Returns the cumulative (summed) XP required to reach the specified target level along a geometric progression curve, giving the total experience points a player must earn from level 1 through the target level.
