## 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-median-calculator-b4ad4e67 -d '<json body>'
```

Example prompt: Calculate the median of these numbers for me: [3, 7, 2, 9, 6, 1, 8, 4, 5].

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use median calculation without signing up for a full statistical service. It is ideal for agents that need verifiable, on-demand numeric statistics with USDC micropayment settlement on Base or Solana, especially when handling up to 10,000 data points and wanting exact, auditable pricing per call.

## Known failure modes

- Empty array submitted — requires at least 1 value
- Array exceeds 10,000 items limit — request rejected
- Non-numeric values in array — schema validation failure
- Payment failure via x402 — 402 response returned before computation
- Malformed JSON body — 400 error

## 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 computed median value, the count of input numbers processed, and a schema identifier string ('delx/median/v1') for result verification.
