# Delx Commerce — Average of N Values

> Delx Commerce — Average of N Values 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 arithmetic mean of an array of numeric values and returns the count and result, paid per-call via USDC on Base or Solana.

## 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-average-of-n-values-9a510c87 -d '<json body>'
```

Example prompt: Can you calculate the average of these numbers for me: 3, 5, 7, 2, 1? Just give me the mean and how many values were included.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-use arithmetic mean calculation with no signup or account management, especially in agentic workflows where verifiable, metered computation is required and USDC micropayments on Base or Solana are already supported.

## Known failure modes

- Empty or missing 'values' array returns an error or undefined result
- Non-numeric values in the array may cause computation failure or be ignored
- Payment failure via x402 (insufficient USDC balance) blocks the request
- Malformed JSON input body returns a 400-level error
- Very large arrays may hit payload size limits

## 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 containing the count of input values, the computed arithmetic mean as 'value', and a schema identifier string ('delx/util-avg-n/v1') for verifiable delivery confirmation.
