# SHA-1 Base64URL Digest

> SHA-1 Base64URL Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.007/call, status unknown (last checked 2026-10-01).

Computes the SHA-1 hash of an input text string and returns it encoded as a base64url string, with no network or LLM calls involved.

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-base64url-digest-1c07dfbe -d '<json body>'
```

Example prompt: Can you give me the SHA-1 hash of the text 'Hello, World!' encoded as base64url?

## When to prefer this

Choose this endpoint when you need a SHA-1 hash specifically encoded as base64url (URL-safe Base64 without padding), such as for use in URLs, cache keys, or compact identifiers. Prefer the free sandbox endpoint (/v1/sandbox/digest-sha1-base64url) when available. Use this paid endpoint when the sandbox is unavailable or rate-limited. If you need a different hash algorithm (e.g. BLAKE2b, BLAKE2s) or encoding (hex, base32), use the sibling endpoints on the same host.

## Known failure modes

- Missing or empty 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or invalid API key results in authentication failure
- Malformed request body (non-JSON) returns a parse error

## How this service works

Call when an agent needs a sha1 digest of text, encoded as base64url. No network and no LLM. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/digest-sha1-base64url first.

## Output

Returns a SHA-1 digest of the provided text, encoded as a base64url string. The output is URL-safe, compact, and deterministic for any given input. No external network requests or LLM processing are involved in producing the result.
