# SHA-512 Hex Digest (Latin1) — agentshelf.syntexa.ch

> SHA-512 Hex Digest (Latin1) — agentshelf.syntexa.ch is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

Computes a SHA-512 hash of Latin1-encoded text and returns the result as a lowercase hex string.

## 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-hex-digest-latin1-agentshelf-syntexa-ch-6e4adcb2 -d '<json body>'
```

Example prompt: Can you compute the SHA-512 hex digest of this Latin1-encoded text: 'Héllo wörld, this is my document content'?

## When to prefer this

Use this endpoint when you specifically need a SHA-512 hash of Latin1-encoded (ISO-8859-1) text returned as a hex string — for example, when hashing legacy content, European-language documents with accented characters, or any data where the Latin1 byte encoding is required rather than UTF-8. Prefer the free sandbox version (/v1/sandbox/digest-sha512-hex-latin1) for testing before incurring the $0.01 USDC cost here.

## Known failure modes

- Input text contains characters outside the Latin1 range (U+0000–U+00FF), causing encoding errors
- Text or key field is empty or exceeds maxLength (100,000 chars for text, 512 for key)
- Payment of $0.01 USDC not provided or fails, resulting in 402 Payment Required
- Network timeout or service unavailability returns a 5xx error

## How this service works

Call when an agent needs a sha512 digest of latin1 bytes, encoded as hex. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-hex-latin1 first.

## Output

Returns a SHA-512 hash of the provided Latin1 text as a hex-encoded string. The digest is 128 hex characters long (512 bits), deterministically derived from the input text treated as Latin1 bytes.
