SHA-512/256 Hex Digest of Latin1 Bytes
x402
SHA-512/256 Hex Digest of Latin1 Bytes is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-29).
Computes a SHA-512/256 cryptographic hash of latin1-encoded bytes and returns the result as a lowercase hexadecimal string.

How this service works
Call when an agent needs a sha512-256 digest of latin1 bytes, encoded as hex. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-256-hex-latin1 first.
Output
Returns a lowercase hexadecimal string representing the SHA-512/256 cryptographic digest of the input text interpreted as latin1-encoded bytes. The hash is deterministic and fixed-length (64 hex characters).
Example use cases
Content integrity fingerprinting
“Hash this latin1 text with SHA-512/256 and give me the hex digest so I can use it as a checksum — the text is 'Invoice #4821: total $340.00' and the key is 'invoice-check'.”
Deterministic ID from legacy data
“I have a legacy latin1-encoded record with content 'user:john.doe|role:admin|ts:1700000000' and I need a SHA-512/256 hex hash using key 'record-id' to create a stable identifier for it.”
Security audit hash logging
“Generate the SHA-512/256 hex digest for this latin1 string 'config_v2:host=db01;port=5432;ssl=true' using key 'audit-log' so I can log it for tamper detection.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha512-256-hex-latin1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need SHA-512/256 (the SHA-512 algorithm truncated to 256 bits, distinct from SHA-256) applied to latin1-encoded byte interpretation of your text, with the result as a hex string. Prefer this over the sandbox variant when operating in production. Use this instead of SHA-256 or SHA-3 endpoints when your security protocol or compliance requirement explicitly calls for SHA-512/256. It is ideal when interoperating with systems that treat input as latin1 bytes rather than UTF-8.
Side effects
- Input text exceeds 100,000 character limit — request rejected
- Key is empty or exceeds 512 characters — validation error
- Text contains characters outside latin1 range — encoding error or undefined behavior
- Payment of $0.004 USDC not provided — 402 Payment Required response
- Missing required fields (key or text) — schema validation failure
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. |
