How this service works
Call when an agent needs a sha256 digest of latin1 bytes, encoded as base64url. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/digest-sha256-base64url-latin1 first.
Output
Returns a SHA-256 digest of the provided Latin-1 text, encoded as a base64url string. The output is a compact, URL-safe representation of the cryptographic hash suitable for use in ETags, checksums, deduplication keys, or integrity verification.
Example use cases
Integrity fingerprint for stored content
“I need a SHA-256 fingerprint of this Latin-1 product description — encode the digest as base64url so I can use it as an ETag: 'Produit de qualité supérieure, fabriqué en France.'”
Canonical hash for deduplication pipeline
“Hash this Latin-1 string as SHA-256 and return base64url so I can deduplicate records in my pipeline: 'Müller, Hans, Straße 12'”
Signing key derivation checksum
“Give me the SHA-256 base64url digest of the key 'mySecretKey' combined with the text 'invoice-2024-09-01' — I need the hash to verify data integrity in my signing workflow.”

Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha256-base64url-latin1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA-256 hash of Latin-1 (ISO-8859-1) encoded text returned in base64url format — particularly useful when dealing with legacy Western European text data or when you need a URL-safe hash. If a free sandbox version (POST /v1/sandbox/digest-sha256-base64url-latin1) is available, prefer that first to avoid the $0.002 USDC charge.
Side effects
- Input text contains characters outside the Latin-1 range (above U+00FF), which may cause encoding errors or unexpected results
- Text or key field is empty or exceeds the maxLength of 512/100000 characters, resulting in a validation error
- Network or payment failure causes a 402 or 5xx response
- Malformed request body returns a 400 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. |
