# SHA-1 Base64 Latin-1 Digest

> SHA-1 Base64 Latin-1 Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.007/call, status unknown (last checked 2026-10-02).

Computes a SHA-1 hash of a Latin-1 encoded text string and returns it as a Base64-encoded digest

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-base64-latin-1-digest-01c2917f -d '<json body>'
```

Example prompt: Can you compute the SHA-1 hash of the Latin-1 encoded text 'Hello World' and give me the result as a Base64 string?

## When to prefer this

Choose this endpoint when you specifically need a SHA-1 digest of text interpreted as Latin-1 (ISO-8859-1) bytes and the result encoded in Base64. This is the right choice for legacy system integrations, older protocols, or checksum schemes that mandate Latin-1 encoding rather than UTF-8. Prefer the free sandbox endpoint /v1/sandbox/digest-sha1-base64-latin1 for testing before committing the $0.007 USDC paid call.

## Known failure modes

- Text contains characters outside the Latin-1 (ISO-8859-1) range, causing encoding errors
- Input text exceeds the 100,000 character maximum length limit
- Key parameter is missing or exceeds 512 characters
- Network timeout or service unavailability returns a 5xx error
- Payment authorization failure (x402) if USDC payment is not properly attached

## How this service works

Call when an agent needs a sha1 digest of latin1 bytes, encoded as base64. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/digest-sha1-base64-latin1 first.

## Output

Returns a Base64-encoded SHA-1 digest computed from the Latin-1 (ISO-8859-1) byte representation of the input text. The result is a deterministic, fixed-length cryptographic hash suitable for integrity checking or fingerprinting legacy-encoded content.
