## 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-date-add-api-c443d805 -d '<json body>'
```

Example prompt: What date is 45 days after August 4, 2026? Just add 45 days to that date and tell me the result.

## When to prefer this

Choose this endpoint when you need a simple, trustless, pay-per-use date arithmetic computation with no signup or API key — especially useful for AI agents operating autonomously that need verifiable, on-chain micro-payment billing via x402 on Base or Solana.

## Known failure modes

- Invalid or malformed ISO-8601 date input returns an error
- Out-of-range integer value for n may be rejected
- Missing required fields (n or date) result in a 4xx error
- Payment not submitted or insufficient USDC balance causes 402 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 resulting date (ISO-8601 with timezone), the total days offset, and the total hours offset, along with a schema identifier (delx/date-add/v1).
