MD5 Hex Digest of Raw Hex Bytes
x402
MD5 Hex Digest of Raw Hex Bytes is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-02).
Computes an MD5 digest of raw bytes supplied as a hex-encoded string, returning the result as a lowercase hex string.

How this service works
Call when an agent needs a md5 digest of hex bytes, encoded as hex. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/digest-md5-hex-rawhex first.
Output
Returns the MD5 digest of the raw bytes represented by the input hex string, encoded as a lowercase hexadecimal string (32 hex characters for standard MD5 output).
Example use cases
Verify binary file integrity via MD5
“I have a binary chunk represented as hex — '4d546869735f697320612074657374' — can you get its MD5 digest in hex so I can compare it against our stored checksum?”
Fingerprint protocol packet bytes
“We captured a network packet and stored it as hex bytes: 'cafebabe00010002'. Compute the MD5 fingerprint of those raw bytes in hex for logging purposes.”
Deduplicate binary blobs by hash
“I need to deduplicate some binary objects. Here are the raw bytes in hex for the first one: 'aabbccddeeff0011'. Give me its MD5 hash as hex so I can use it as a dedup key.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-md5-hex-rawhex?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to hash raw binary data that is represented as a hex-encoded string and want the MD5 result back in hex. Prefer the free sandbox equivalent (/v1/sandbox/digest-md5-hex-rawhex) for development and testing to avoid the $0.003 USDC charge. Choose this over text-based MD5 endpoints when the input is binary (not UTF-8 text) and must be treated as raw bytes decoded from hex.
Side effects
- Invalid or non-hex input string causes a 400 error
- Empty input rejected (minLength:1 enforced)
- Input exceeding 100,000 characters returns a payload-too-large error
- Payment not provided or incorrect amount results in 402 Payment Required
- Network timeout on agent side if processing unusually large hex strings
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| key | string | HMAC secret. Required on HMAC SKUs. Omit it for plain digests and checksums. The key is not stored. |
| text | string | Message to digest. For raw-hex SKUs this is hex bytes; for utf16 or latin1 SKUs it is decoded with that encoding. Otherwise it is UTF-8 text. |
