# Delx Commerce Percentile Calculator

> Delx Commerce Percentile Calculator is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

Computes the Nth percentile of a provided numeric dataset, returning the percentile value and sample count.

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 delx-commerce-percentile-calculator-cc4db7c4 -d '<json body>'
```

Example prompt: Calculate the 95th percentile of these response times in milliseconds: [120, 340, 210, 89, 450, 310, 670, 150, 280, 95] — I need the p95 value.

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call percentile computation without account setup, especially inside an agent workflow that already handles x402 micropayments in USDC. Ideal for on-demand statistical analysis of numeric datasets up to 10,000 values, where reproducible, verifiable results and exact pricing matter.

## Known failure modes

- Empty array input — request rejected (minItems: 1 required)
- Array exceeds 10,000 items — request rejected (maxItems: 10000)
- Non-numeric values in array — parsing or validation error
- Percentile out of 0–100 range — validation error
- Payment failure or insufficient USDC balance — 402 payment required response

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object with the computed percentile value (`value`), the requested percentile rank (`p`), the count of input samples (`count`), and a schema identifier (`schema: 'delx/percentile/v1'`).
