x402
SHA3-512 Hex Digest (Latin1) — agentshelf.syntexa.ch is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).
Computes a SHA3-512 cryptographic digest of Latin1-encoded bytes and returns the result as a lowercase hex string.

How this service works
Call when an agent needs a sha3-512 digest of latin1 bytes, encoded as hex. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-512-hex-latin1 first.
Output
Returns a 128-character lowercase hexadecimal string representing the SHA3-512 digest of the input text treated as Latin1-encoded bytes. No state is stored; the result is deterministic for identical inputs.
Example use cases
Document integrity fingerprinting
“I need to generate a SHA3-512 hex hash of this Latin1 text so I can store it as a tamper-proof fingerprint: 'Contract version 1.0 — Acme Corp, signed 2024-01-15.'”
Pipeline checksum generation
“Before I archive this log entry, compute the SHA3-512 digest in hex of this Latin1 string: 'ERROR 503 gateway timeout at 2024-06-10T14:32:00Z on node eu-west-2.'”
Deduplication hash for content store
“I want to deduplicate stored records — can you hash this Latin1 text with SHA3-512 and give me the hex output? The text is: 'User profile: John Doe, account #88421, tier: gold.'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-512-hex-latin1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA3-512 digest (not SHA-256, MD5, or SHA-1) of text treated as Latin1 bytes, returned as hex — for example when downstream systems expect the Keccak-derived SHA3 family. If cost is a concern, try the free sandbox endpoint POST /v1/sandbox/digest-sha3-512-hex-latin1 first. Prefer this over the HMAC-SHA3-512 sibling when no secret key is required.
Side effects
- Input text exceeds 100,000 character limit — request rejected
- Text contains characters not representable in Latin1 encoding — may produce unexpected results
- Empty string input rejected due to minLength:1 constraint
- Payment of $0.002 USDC not fulfilled — 402 Payment Required response
- Network timeout or service unavailability — 5xx 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. |
