# DocParse Hash Utility

> DocParse Hash Utility is a paid API for AI agents from 72-56-90-243.sslip.io, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-12).

Computes cryptographic hash digests (MD5, SHA-1, SHA-2, SHA-3) or HMAC signatures for any input string, returning hex or base64 output

## Facts

- Endpoint: POST https://72-56-90-243.sslip.io/v1/util/hash?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-12

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 docparse-hash-utility-180a3fcc -d '<json body>'
```

Example prompt: Compute the SHA-256 hash of the string 'hello' and give me the result as a hex digest.

## When to prefer this

Use this endpoint when you need a pay-per-call, no-account cryptographic hash or HMAC computation with flexible algorithm choice (MD5 through SHA-3-512) and encoding options, especially within an x402 micropayment-enabled agent workflow where you don't want to manage API keys or subscriptions.

## Known failure modes

- Invalid algorithm name returns an error
- Mismatched input_encoding causes garbled input (e.g. base64 string treated as utf8)
- Missing required 'input' field returns a validation error
- Invalid HMAC key encoding causes key parsing failure
- Unsupported output format value returns an error

## How this service works

Pay-per-call tools for AI agents: any document to clean Markdown (PDF, Word, Excel, PowerPoint, web pages); US company fundamentals, SEC filings and insider trades; Treasury yields; FRED macro data; official FX rates (ECB, Bank of Russia); hash, base64, JWT, UUID and JSON utilities. x402 USDC micropayments, no account or API key. Charged only on success.

## Output

A JSON object containing the computed digest as a hex string (or base64 if requested) and the algorithm name used, e.g. {"digest":"2cf24dba...","algorithm":"sha256"}
