## 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 gocreative-date-difference-calculator-f783b6d6
```

Example prompt: How many days are between January 15, 2023 and November 3, 2024?

## When to prefer this

Use this endpoint when an AI agent needs a quick, reliable, no-signup date arithmetic calculation — specifically the span between two calendar dates — without setting up any API credentials. At $0.005 per call it is suitable for high-frequency agent workflows that need to compute elapsed time, deadline proximity, age, or scheduling gaps.

## Known failure modes

- Invalid or unparseable date strings cause an error response
- Missing required 'input' query parameter returns a 400-level error
- Malformed date format (e.g. ambiguous separators) may cause incorrect parsing
- Swapped start/end dates may return a negative or unexpected value
- Future dates beyond supported range may return an error

## How this service works

Keyless, pay-per-call compliance & regulated-data API for AI agents — OFAC wallet + sanctions/PEP + KYB screening, SEC filings, FRED economics, FDA recalls, federal awards, plus continuous monitoring. USDC on Base/Solana via x402, native MCP. No API key, no signup.

## Output

Returns the computed difference between two dates, likely expressed as a count of days (and possibly weeks, months, or years) separating the two input dates.
