How this service works
Call when an agent needs a md5 digest of hex bytes, encoded as base64url. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/digest-md5-base64url-rawhex first.
Output
A base64url-encoded string representing the MD5 digest of the raw bytes decoded from the provided hex input. The result is a compact, URL-safe hash suitable for checksums, fingerprints, or integrity verification tokens.
Example use cases
Integrity fingerprint for binary payload
“I have some raw binary data represented as hex: deadbeefcafebabe01234567. Can you compute its MD5 hash and return it as a base64url string so I can use it as a compact integrity fingerprint?”
Message authentication with keyed hash
“I need to generate an MD5 digest in base64url for these hex-encoded bytes — 0a1b2c3d4e5f — using the key 'mySecretKey'. Can you do that for me?”
Checksum verification token for API pipeline
“Our pipeline expects a base64url-encoded MD5 of the raw hex bytes '7f454c46020101000000000000000000'. Can you produce that checksum so I can pass it along as a verification token?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-md5-base64url-rawhex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need an MD5 hash computed over raw bytes that are expressed as a hex string, with the output encoded in base64url (not hex or standard base64). Prefer the free sandbox equivalent at POST /v1/sandbox/digest-md5-base64url-rawhex when available. Use this paid version when the sandbox is unavailable, rate-limited, or when a reliable paid SLA is required.
Side effects
- Invalid hex string (odd length or non-hex characters) causes a 400 error
- Empty text or key fields rejected due to minLength:1 constraint
- Text exceeding 100,000 characters returns a validation error
- Payment not processed results in HTTP 402 Payment Required
- Malformed request 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. |
