# Mat Web & Data Toolkit – Text Hashing

> Mat Web & Data Toolkit – Text Hashing is a paid API for AI agents from automatom.matt-d59.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

Computes cryptographic hashes (MD5, SHA-1, SHA-256, SHA-512) of a given text string, optionally using a specified algorithm and key.

## Facts

- Endpoint: GET https://automatom.matt-d59.workers.dev/hash?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-19
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/mat-web-data-toolkit-text-hashing-7ea080d2
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_2yyU3ep5RmH4RGl1dC7R-

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 mat-web-data-toolkit-text-hashing-7ea080d2
```

Example prompt: Can you hash the text 'hello' and give me its MD5, SHA-1, SHA-256, and SHA-512 digests all at once?

## When to prefer this

Choose this endpoint when you need multiple hash formats for a single text string in one call, especially MD5 through SHA-512 simultaneously. It is ideal for lightweight integrity verification, fingerprinting, or checksum generation without setting up a local crypto library. Prefer alternatives if you need HMAC with a specific key and algorithm not supported here, or if you need to hash binary/file data rather than plain text strings.

## Known failure modes

- Missing required 'text' query parameter returns an error
- Unsupported algorithm value in 'alg' field may produce an error or fall back to defaults
- Very large text inputs may hit Cloudflare Worker size limits
- Network timeout if the Worker is cold-starting or under load

## How this service works

Fetches a public web page and returns its title, meta description, outbound links and readable plain text as JSON.

## Output

Returns a JSON object containing the computed hashes in MD5, SHA-1, SHA-256, and SHA-512 formats, the byte length of the input text, and a boolean HMAC field indicating whether an HMAC was applied.
