# SHA-1 Hex-Bytes to Hex Digest

> SHA-1 Hex-Bytes to Hex Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-02).

Computes a SHA-1 digest of raw bytes supplied as a hex string and returns the result encoded as a hexadecimal 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-1-hex-bytes-to-hex-digest-981b7538 -d '<json body>'
```

Example prompt: Compute the SHA-1 hash of these hex-encoded bytes — 'deadbeef0102030405' — and give me the result as a hex string.

## When to prefer this

Choose this endpoint when you need a SHA-1 digest of raw binary data supplied as a hex string and want the result returned in hexadecimal format. Prefer the free sandbox version (/v1/sandbox/digest-sha1-hex-rawhex) for testing or when cost matters. Use this paid endpoint when the sandbox is unavailable, rate-limited, or when operating in production environments that require guaranteed SLA. Prefer SHA-256 or SHA-512 endpoints on the same platform when stronger cryptographic guarantees are required.

## Known failure modes

- Invalid hex string input (odd-length or non-hex characters) — likely 400 Bad Request
- Input text exceeds 100,000 character limit — rejected at schema validation
- Missing required 'text' field — 400 Bad Request
- 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 hex bytes, encoded as hex. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/digest-sha1-hex-rawhex first.

## Output

Returns a SHA-1 digest of the input hex bytes, encoded as a lowercase hexadecimal string (40 characters). The endpoint performs no storage and is fully deterministic for a given input.
