# Numora Percentile Computation

> Numora Percentile Computation is a paid API for AI agents from numormo.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Computes the Nth percentile value from a dataset of numbers with no external dependencies

## Facts

- Endpoint: POST https://numormo.vercel.app/api/statistics/percentile
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

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-computation-19ea76c9 -d '<json body>'
```

Example prompt: Calculate the 95th percentile from this list of response times: [120, 340, 89, 560, 230, 410, 77, 980, 150, 290, 670, 44].

## When to prefer this

Choose this endpoint when you need a fast, dependency-free percentile calculation on a numeric dataset and want a simple POST-based API with per-call micropayment pricing. Ideal for agents that need statistical computations without setting up a full data science stack or calling a heavyweight analytics platform.

## Known failure modes

- Empty or null data array returns an error
- Percentile value outside 0-100 range is invalid
- Non-numeric values in the data array may cause computation failure
- Insufficient funds (x402 payment required at $0.1 USDC per call)

## 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 computation string describing what was calculated in human-readable form.
