How this service works
Call when an agent needs a blake2s256 digest of latin1 bytes, encoded as base64url. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/digest-blake2s256-base64url-latin1 first.
Output
A JSON response containing the Base64URL-encoded BLAKE2s-256 digest of the provided Latin-1 text hashed with the given key.
Example use cases
Integrity check for stored records
“Take this Latin-1 encoded log entry "user=alice;action=login;ts=1700000000" and hash it with BLAKE2s-256 using key "auditkey" — I need the Base64URL digest to verify the record hasn't been tampered with.”
Keyed MAC for API payloads
“I need to generate a keyed BLAKE2s-256 digest of this payload text "amount=500¤cy=USD&ref=ord-99" using key "webhooksecret", encoded as Base64URL, so I can include it as a message authentication code.”
Deduplication fingerprint for Latin-1 content
“Hash this Latin-1 text "Bonjour le monde, ça va?" with BLAKE2s-256 and key "dedup" and return the Base64URL result — I'm building a deduplication index for legacy text records.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-blake2s256-base64url-latin1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, keyed cryptographic digest of Latin-1 text specifically using the BLAKE2s-256 algorithm with Base64URL output encoding — common for legacy system integrations, compact MAC generation, or deduplication of Latin-1 encoded content. Prefer the free sandbox endpoint /v1/sandbox/digest-blake2s256-base64url-latin1 for testing before paying.
Side effects
- Text or key exceeds maximum length limits (100,000 chars for text, 512 chars for key)
- Text contains characters outside the Latin-1 range (code points > 255)
- Missing required fields (key or text) result in a 4xx error
- Non-Latin-1 encodings silently produce unexpected hashes if input is misinterpreted
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. |
