# Text Hash (SHA-256/SHA-1/SHA-512/SHA-384)

> Text Hash (SHA-256/SHA-1/SHA-512/SHA-384) is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns SHA-256, SHA-1, SHA-512, and SHA-384 hex digests plus byte length of any UTF-8 text 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 text-hash-sha-256-sha-1-sha-512-sha-384-c3ae2147
```

Example prompt: Compute the SHA-256, SHA-1, SHA-512, and SHA-384 hex digests and byte length for this exact text: 'Hello, world! This is my input string.'

## When to prefer this

Use this endpoint when you need multiple standard hash digests (SHA-256, SHA-1, SHA-512, SHA-384) computed simultaneously for a single text value in one round trip, without deploying a local hashing library. It is ideal for agent workflows needing deduplication keys, integrity fingerprints, or checksums over user-supplied or pipeline-generated text without executing arbitrary code locally.

## Known failure modes

- Missing 'input' query parameter returns an error
- Empty string input may return zero-byte hashes
- Non-UTF-8 encoding edge cases may cause unexpected byte length
- Payment failure (x402) if USDC balance is insufficient
- Timeout or 5xx from upstream service under load

## How this service works

Text hashes: SHA-256, SHA-1, SHA-512 and SHA-384 hex digests of the exact text you send (UTF-8), plus its byte length. Deduplication keys, integrity checks and fingerprints. $0.01 per call.

## Output

A JSON object containing four hex digest strings (SHA-256, SHA-1, SHA-512, SHA-384) computed over the exact UTF-8 bytes of the input text, along with the byte length of the input. All four digests are returned in a single response.
