How this service works
Call when an agent needs a sha512 digest of hex bytes, encoded as hex. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-hex-rawhex first.
Output
A hex-encoded SHA-512 digest string computed from interpreting the input 'text' field as raw hex bytes. The response contains the 128-character lowercase hexadecimal representation of the 512-bit hash.
Example use cases
Integrity check of binary payload
“I have some raw binary data represented as hex — '4d546869736973' — and I need its SHA-512 digest in hex so I can verify it hasn't been tampered with. Can you compute that for me?”
Cryptographic fingerprint for audit log
“For our audit log I need a SHA-512 hex fingerprint of this raw hex data: 'a1b2c3d4e5f60718'. Can you hash it and return the hex digest?”
Chaining hash in data pipeline
“In our processing pipeline I need to pass the SHA-512 hex digest of this hex-encoded chunk — 'ff00aa1122334455' — to the next stage. Please compute the hash as hex.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha512-hex-rawhex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to hash raw binary data that is already hex-encoded and require the SHA-512 digest returned in hex format. Prefer the free sandbox variant (/v1/sandbox/digest-sha512-hex-rawhex) before paying. Use this paid version when the sandbox is unavailable or rate-limited.
Side effects
- Input 'text' is not valid hexadecimal — returns a 4xx error
- Input 'text' exceeds 100,000 character limit — payload too large error
- Missing required fields — validation error returned
- Payment not included or insufficient — 402 Payment Required
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. |
