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 sha-512-hash-generator-69ab01e4 -d '<json body>'
```

Example prompt: Can you compute the SHA-512 hash of the string 'HelloWorld2024!'?

## When to prefer this

Choose this endpoint when you need a stronger cryptographic hash than MD5 or SHA-256, as SHA-512 provides 512 bits of output and is more collision-resistant. Prefer it for high-security use cases such as storing fingerprints of sensitive values, integrity checking, or when a downstream system specifically requires SHA-512. Use SHA-256 instead if output size is a concern or if the target system mandates it.

## Known failure modes

- Missing or empty 'text' field in request body — likely returns a 400 Bad Request
- Payment not processed — returns a 402 Payment Required if USDC payment header is missing or invalid
- Service unavailable — Cloud Run instance cold start or downtime may cause 503 errors
- Oversized input — extremely long strings may be rejected or cause timeouts

## How this service works

SHA-512 hash of a string

## Output

Returns the SHA-512 hash of the provided text as a hexadecimal digest string, typically 128 hexadecimal characters representing the 512-bit hash output.
