# Landing en 24h Text Hashing Utility

> Landing en 24h Text Hashing Utility is a paid API for AI agents from landingen24h.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-27).

Hashes UTF-8 text using SHA-1, SHA-256, SHA-384, SHA-512, or all algorithms at once, returning hex and base64 encoded digests.

## Facts

- Endpoint: POST https://landingen24h.com/api/x402/util/hash?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-27
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/landing-en-24h-text-hashing-utility-2d92132d

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 landing-en-24h-text-hashing-utility-2d92132d -d '<json body>'
```

Example prompt: Hash the text 'Hello, World!' using SHA-256 and give me both the hex and base64 digests.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call cryptographic hashing utility that supports multiple SHA algorithms in a single call and returns both hex and base64 encodings simultaneously. Useful for agents that need on-demand integrity checks without managing local crypto libraries or server infrastructure.

## Known failure modes

- Text exceeds 3500 character maxLength — request rejected
- Invalid algorithm value outside the allowed enum — validation error
- Empty or missing text field — may return error or hash of empty string
- Malformed JSON body — HTTP 400 bad request
- Network timeout for very large payloads near the limit
