# SHA-1 Base32 UTF-16LE Digest

> SHA-1 Base32 UTF-16LE Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).

Computes a SHA-1 hash of text encoded as UTF-16LE bytes, then returns the digest encoded as Base32

## Facts

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-1-base32-utf-16le-digest-76c2618a -d '<json body>'
```

Example prompt: Compute a SHA-1 hash of the text 'Hello World' using UTF-16LE byte encoding and give me the result as a Base32 string, using key 'mykey123'.

## When to prefer this

Choose this endpoint when you specifically need a SHA-1 digest computed over UTF-16LE bytes (as used in Windows and many legacy Microsoft systems) and want the result in Base32 encoding. This is distinct from standard SHA-1 (which typically hashes UTF-8 bytes) or SHA-256/MD5 alternatives. Prefer the free sandbox endpoint POST /v1/sandbox/digest-sha1-base32-utf16 for testing; use this paid endpoint in production when reliability and SLA matter.

## Known failure modes

- Text exceeds 100,000 character limit — request rejected
- Key field missing or empty — validation error
- Text field missing or empty — validation error
- Key exceeds 512 character limit — validation error
- Payment not provided or insufficient — 402 Payment Required
- Service temporarily unavailable — 5xx error

## How this service works

Call when an agent needs a sha1 digest of utf16le bytes, encoded as base32. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/digest-sha1-base32-utf16 first.

## Output

Returns a Base32-encoded string representing the SHA-1 digest computed over the UTF-16LE byte representation of the input text. The result is a fixed-length, uppercase Base32 string suitable for use as a checksum, fingerprint, or cache key in systems that require UTF-16LE encoding compatibility.
