# Numora Percentile Calculator

> Numora Percentile Calculator is a paid API for AI agents from numorapoi.orbonomy.xyz, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-14).

Computes the Nth percentile value from a dataset of numbers using pure server-side math with no external dependencies

## Facts

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 numora-percentile-calculator-acff7774 -d '<json body>'
```

Example prompt: Calculate the 95th percentile of this list of response times in milliseconds: [120, 340, 89, 450, 210, 780, 95, 630, 175, 520, 310, 88, 940, 260, 405].

## When to prefer this

Use this endpoint when you need a fast, dependency-free percentile computation with no external service calls. Ideal for agents that need to compute percentile statistics on the fly with x402 micropayments and cannot or prefer not to run local math libraries. Best when you have a concrete numeric array and a specific percentile target.

## Known failure modes

- Missing required field 'p' returns 400 error
- Missing required field 'data' returns 400 error
- Percentile value p outside 0-100 range returns validation error
- Empty data array may return null or error
- Non-numeric values in data array may cause computation failure
- Payment not included or insufficient triggers 402 Payment Required

## How this service works

100 pure math computation endpoints for AI agents. Statistics, financial math, linear algebra, equation solving, calculus, number theory, sequence generation, and unit conversions. Zero external dependencies. x402 micropayments on Base.

## Output

Returns a JSON object with success=true, a result object containing the computed percentile value, and a human-readable computation string describing what was calculated (e.g. 'Computed the 95th percentile of 15 data points').
