## 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-array-take-first-n-elements-073b8cc5 -d '<json body>'
```

Example prompt: Take the first 3 items from this array: [10, 20, 30, 40, 50].

## When to prefer this

Choose this endpoint when you need a simple, stateless, pay-per-call array head-slice with verifiable on-chain payment via x402 (USDC on Base or Solana), and no signup or API key overhead. Prefer it in agent workflows where billing transparency and micro-payment settlement per operation are required. It is best for lightweight utility operations rather than complex data processing.

## Known failure modes

- n exceeds array length — may return all items or an error
- missing required fields (n or items) — likely a 400 bad request
- payment not accepted or insufficient USDC balance — 402 Payment Required
- n is zero or negative — returns empty array or validation error
- non-integer value for n — schema validation failure

## How this service works

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

## Output
