Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 kihustle-crc16-checksum-api-e5a735be -d '<json body>'
```

Example prompt: Can you calculate the CRC16 checksum for the text 'Hello World'?

## When to prefer this

Use this endpoint when you need a simple, fast, low-cost CRC16 checksum computation for a text string via a pay-per-call micropayment API, particularly in x402-compatible agent workflows where you want deterministic error-detection checksums without setting up your own compute infrastructure.

## Known failure modes

- Missing or empty 'text' field in request body returns an error
- Non-string input types may cause processing failure
- Network timeout on the endpoint
- Unexpected server-side error returning generic 'processed' result with ambiguous meaning
