How this service works
Call when an agent needs a sha384 digest of hex bytes, encoded as base64url. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/digest-sha384-base64url-rawhex first.
Output
Returns a base64url-encoded string representing the SHA-384 digest of the input interpreted as raw hex bytes. The result is a compact, URL-safe hash suitable for use in tokens, integrity checks, or digital signatures.
Example use cases
Integrity fingerprint for hex payload
“I have a hex-encoded binary payload '0a1b2c3d4e5f' and I need its SHA-384 hash encoded as base64url so I can attach it as an integrity fingerprint to my API request.”
Verify keyed digest of hex data
“Can you compute the SHA-384 digest of the hex string 'deadbeefcafe0123456789abcdef' using key 'mysecretkey' and give me back the base64url result?”
Hash hex-encoded cryptographic nonce
“Take this hex nonce 'f3a9b1c240de786a' and run it through SHA-384, then return the digest as a base64url string so I can use it in my token generation pipeline.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha384-base64url-rawhex?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a SHA-384 hash specifically of raw hex-encoded bytes (not plain text or binary blobs) and require the output in base64url format. Prefer the free sandbox endpoint `/v1/sandbox/digest-sha384-base64url-rawhex` for testing or cost-sensitive scenarios. Choose this paid endpoint when sandbox access is unavailable or production-grade reliability is required.
Side effects
- Invalid or non-hex input string returns an error
- Input text exceeds 100,000 character limit
- Payment of exactly $0.005 USDC not provided — HTTP 402 returned
- Empty input string rejected due to minLength:1 constraint
- Key field exceeds 512 character limit
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. |
