# SHA-256 Base32 UTF-16LE Digest

> SHA-256 Base32 UTF-16LE Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-02).

Computes a SHA-256 hash of a string encoded as UTF-16LE bytes, then returns the digest encoded as Base32

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-256-base32-utf-16le-digest-05feefdb -d '<json body>'
```

Example prompt: Can you compute the SHA-256 digest of the text 'Hello, World!' using UTF-16LE byte encoding and give me the result as a Base32 string?

## When to prefer this

Choose this endpoint when you specifically need a SHA-256 hash computed over the UTF-16LE byte representation of a string and the output must be Base32-encoded — common for compatibility with Windows, .NET, or Microsoft Office environments that treat strings as UTF-16LE. Use the free sandbox variant (/v1/sandbox/digest-sha256-base32-utf16) for testing before paying. Avoid this if you need standard UTF-8 SHA-256 hashing or a different output encoding like hex or Base64.

## Known failure modes

- Empty or missing 'text' field returns validation error
- Text exceeding 100,000 characters is rejected
- Missing 'key' field may cause authentication failure
- Insufficient USDC balance results in payment failure (x402)
- Non-UTF-8 input that cannot be re-encoded causes processing error

## How this service works

Call when an agent needs a sha256 digest of utf16le bytes, encoded as base32. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/digest-sha256-base32-utf16 first.

## Output

Returns a Base32-encoded string representing the SHA-256 digest of the input text's UTF-16LE byte encoding. This is a deterministic, fixed-length hash useful for integrity checks, deduplication, or interoperability with systems that process text as UTF-16LE (e.g., Windows/.NET environments).
