MD5 Digest of Hex Bytes Encoded as Base64
x402
MD5 Digest of Hex Bytes Encoded as Base64 is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.006/call, status unknown (last checked 2026-10-02).
Computes an MD5 hash of raw bytes specified as hex-encoded input, returning the digest encoded in Base64 format.

How this service works
Call when an agent needs a md5 digest of hex bytes, encoded as base64. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/digest-md5-base64-rawhex first.
Output
Returns a Base64-encoded MD5 digest of the raw bytes decoded from the provided hex-encoded input string. The output is a standard Base64 string representing the 16-byte MD5 hash.
Example use cases
Verify binary file integrity via hash
“I have a file's raw bytes as a hex string — '89504e470d0a1a0a' — can you compute the MD5 digest of those bytes and return it as Base64 so I can verify it matches the expected checksum?”
Checksum hex-encoded cryptographic payload
“Take this hex-encoded payload 'deadbeefcafe0123' and give me its MD5 hash encoded as Base64 — I need to compare it against a reference digest in our system.”
Hash binary protocol data for deduplication
“I'm deduplicating binary messages stored as hex strings. Compute the MD5 Base64 digest of '0102030405060708' so I can use it as a unique fingerprint in my dedup index.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-md5-base64-rawhex?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need an MD5 digest of raw bytes provided as a hex-encoded string, with the result encoded in standard Base64. Prefer the free sandbox endpoint (/v1/sandbox/digest-md5-base64-rawhex) for testing. Choose this over sibling endpoints when your input is hex-encoded binary (not plain UTF-8 text or Latin-1) and your output format must be Base64 (not Base64URL, hex, or Base32).
Side effects
- Invalid hex string input (odd length or non-hex characters) may cause a 400 error
- Input exceeding 100,000 character limit returns a validation error
- Missing required fields returns a 422 unprocessable entity
- Payment failure or insufficient USDC balance results in a 402 Payment Required response
- Malformed JSON body returns a 400 bad request
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. |
