How this service works
Call when an agent needs a sha384 digest of text, encoded as base64. No network and no LLM. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/digest-sha384-base64 first.
Output
A base64-encoded SHA-384 digest (512-bit hash, base64-encoded to roughly 64 characters) of the input text. The result is deterministic and consistent — the same input always yields the same digest. No network calls or LLM inference are involved.
Example use cases
Content integrity fingerprinting
“I need to generate a SHA-384 digest encoded in base64 for the string 'The quick brown fox jumps over the lazy dog' — I want to store it as a fingerprint to verify the content hasn't changed later.”
API signature verification prep
“Hash this JSON payload using SHA-384 and return it in base64 so I can include it in a request signature header: '{"user":"alice","action":"transfer","amount":100}'”
Password hashing for storage
“Compute the SHA-384 base64 digest of the string 'mysecretpassword123' so I can store a hashed version instead of the plaintext.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha384-base64?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a SHA-384 hash (not SHA-256, SHA-512, BLAKE2, or MD5) specifically encoded as standard base64 (not base64url or hex). It is fully deterministic with no external network calls or LLM inference, making it reliable and fast. A free sandbox version at POST /v1/sandbox/digest-sha384-base64 should be tried first; use this paid endpoint when the sandbox is unavailable or production guarantees are needed.
Side effects
- Missing or empty 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Invalid or missing API key returns a 402 or authentication error
- Malformed JSON body returns a 400 error
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. |
