# SHA-512/256 Digest — Base32 Latin1 Encoding

> SHA-512/256 Digest — Base32 Latin1 Encoding is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-29).

Computes a SHA-512/256 hash of Latin1-encoded text and returns it as a Base32-encoded digest string.

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-512-256-digest-base32-latin1-encoding-9f5df826 -d '<json body>'
```

Example prompt: Compute the SHA-512/256 hash of the text 'Hello, World!' using Latin1 encoding and give me the result as a Base32 string.

## When to prefer this

Choose this endpoint when you specifically need a SHA-512/256 hash (not SHA-256 or SHA-512) of Latin1-encoded bytes returned in Base32 format. Prefer the free sandbox endpoint (/v1/sandbox/digest-sha512-256-base32-latin1) for testing. Use this paid endpoint when the sandbox is unavailable or rate-limited, or when operating in production where reliability is required.

## Known failure modes

- Input text contains characters outside the Latin1 (ISO-8859-1) range, causing encoding errors
- Text or key exceeds maximum length limits (100,000 and 512 characters respectively)
- Empty input strings rejected due to minLength:1 constraint
- Payment failure or insufficient USDC balance ($0.003 required)
- Network timeout or service unavailability

## How this service works

Call when an agent needs a sha512-256 digest of latin1 bytes, encoded as base32. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-256-base32-latin1 first.

## Output

Returns a Base32-encoded SHA-512/256 digest string computed from the Latin1 byte representation of the input text. The result is a deterministic, fixed-length hash string suitable for integrity checks, deduplication, or fingerprinting.
