SHA3-256 / Base64 / Latin1 Hash Digest Service
x402
SHA3-256 / Base64 / Latin1 Hash Digest Service is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-24).
Computes a SHA3-256 cryptographic digest of text encoded as Latin1 bytes, returning the result as a Base64 string.

How this service works
Call when an agent needs a sha3-256 digest of latin1 bytes, encoded as base64. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-256-base64-latin1 first.
Output
Returns a Base64-encoded SHA3-256 hash digest computed from the input text treated as Latin1 bytes. The output is a compact, URL-safe string suitable for checksums, deduplication fingerprints, or data integrity verification.
Example use cases
Data integrity verification for stored content
“Take this product description — 'Réservation confirmée pour le séjour à París' — and compute its SHA3-256 hash using Latin1 encoding, returned as Base64, so I can store it as a checksum.”
Deduplication fingerprinting for document pipeline
“I need a SHA3-256 Base64 fingerprint of the following Latin1 text so I can detect duplicates in my pipeline: 'Invoice #4821: Total due $150.00 for services rendered.'”
Tamper-detection token for API payloads
“Generate a SHA3-256 digest in Base64 for this Latin1-encoded string 'status=active&user=jdoe&role=admin' so I can include it as a tamper-detection token in my API response.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-256-base64-latin1?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need a SHA3-256 digest of text that is expected to be in the Latin1 character set, with the result encoded as standard Base64. Prefer the free sandbox endpoint (/v1/sandbox/digest-sha3-256-base64-latin1) for testing. Choose this over sibling SHA-512 variants when SHA3-256 is required by a downstream system or security standard. Choose this over hex-encoded variants when Base64 output is required for compactness or compatibility with Base64-aware systems.
Side effects
- Text contains characters outside the Latin1 range (U+0000–U+00FF), which may cause encoding errors or unexpected results
- Missing or invalid API key results in authentication failure
- Input text exceeds 100,000 character limit, resulting in a rejection error
- Empty text or key fields return a validation error
- Network timeout if the service is temporarily unavailable
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. |
