## 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-round-to-n-decimal-places-6e6228ee -d '<json body>'
```

Example prompt: Round 3.14159 to 2 decimal places for me.

## When to prefer this

Use this endpoint when an AI agent needs a simple, verifiable, pay-per-use rounding operation with no signup overhead. Prefer it over client-side rounding when audit-trail or blockchain-verifiable computation delivery is required, or when operating in a fully agent-automated USDC payment pipeline on Base or Solana.

## Known failure modes

- Missing 'value' field returns validation error
- Missing 'digits' field returns validation error
- Non-numeric 'value' causes a type error
- Negative or very large 'digits' may return unexpected results
- Payment failure via x402 causes 402 response before computation

## 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 rounded value, the number of digits specified, and a schema identifier string ('delx/util-round-n/v1') confirming the result format.
