# AgentTools Hash Digest Generator

> AgentTools Hash Digest Generator is a paid API for AI agents from agentstoolshub.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-12).

Computes exact cryptographic hash digests (SHA-256, SHA-512, SHA-1, MD5) of any UTF-8 text string, returning a deterministic hex 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 agenttools-hash-digest-generator-6977b64e
```

Example prompt: Can you compute the SHA-256 hash of the text 'Hello, World!' for me?

## When to prefer this

Choose this endpoint when you need a deterministic cryptographic hash of a text string using one of the four standard algorithms (SHA-256, SHA-512, SHA-1, MD5). It is particularly useful for data integrity checks, deduplication fingerprinting, legacy MD5 compatibility, and any scenario where you need a fast, reproducible digest without setting up local crypto libraries. Prefer SHA-256 or SHA-512 for security-sensitive use cases; use MD5 only for legacy compatibility.

## Known failure modes

- Missing required 'text' query parameter — returns 400 error
- Invalid 'algo' value outside the enum (sha256, sha512, sha1, md5) — returns validation error
- Non-UTF-8 or extremely large text strings may cause processing errors
- Network timeout or service unavailability returns a 5xx error

## How this service works

Compute exact hash digests of UTF-8 text using Web Crypto (SHA family) and a verified pure-JS MD5 for legacy checksums. Deterministic — identical input always yields the identical digest. Use this when an agent needs to sHA-256 / SHA-512 / SHA-1 / MD5, exact digests.

## Output

Returns the hex-encoded hash digest of the input text, along with the algorithm used. The digest is deterministic — identical text and algorithm always produce the same output. No state is stored.
