DocParse Hash Utility
x402
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

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"}
Example use cases
Verify file content integrity
“Hash this string using SHA-512 and output it as hex so I can verify the content hasn't changed: 'The quick brown fox jumps over the lazy dog'”
Generate HMAC signature for webhook
“Compute an HMAC-SHA256 signature for the message 'order_id=12345&amount=99.99' using the secret key 'mysecretkey' encoded as utf8, give me the hex output.”
Compute MD5 checksum for legacy system
“I need an MD5 hash of this base64-encoded data 'aGVsbG8gd29ybGQ=' — treat the input as base64 and return the digest as hex.”

Endpoint
POSThttps://72-56-90-243.sslip.io/v1/util/hash?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
