## 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 whatchuneed-verify-compare-7d5eebb1 -d '<json body>'
```

Example prompt: Compare these two product descriptions and tell me which one is more accurate or which claims match: 'Product A is waterproof and lasts 10 hours' vs 'Product A is water-resistant and lasts 8 hours'.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call comparison or verification operation without setting up a dedicated comparison service. Ideal for agents that need ad-hoc validation or comparison of two entities or claims, especially within the whatchuneed multi-API ecosystem where a single payment method covers all calls.

## Known failure modes

- Missing or empty 'input' field causes request failure
- Ambiguous or malformed comparison input may yield unreliable results
- API gateway downtime may return non-200 responses
- Insufficient USDC balance for x402 payment causes payment failure
- Input too long or malformed may cause processing errors
