How this service works
Call when an agent needs a sha256 digest of latin1 bytes, encoded as hex. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/digest-sha256-hex-latin1 first.
Output
Returns a lowercase hexadecimal string representing the SHA-256 digest of the input text treated as Latin-1 encoded bytes. The hex string is 64 characters long (256 bits).
Example use cases
Content integrity fingerprinting
“Hash this product description using SHA-256 hex with Latin-1 encoding so I can store a fingerprint and detect if it changes later: 'Premium wireless headphones with 30-hour battery life and noise cancellation.'”
Keyed text hashing for deduplication
“I need a SHA-256 hex digest of the Latin-1 bytes for this invoice text 'INV-2024-00123 Total: €450.00' — use key 'invoices' to namespace it.”
Checksum generation for API payload
“Give me the SHA-256 hex hash of the Latin-1 encoded payload 'amount=100¤cy=USD&merchant=Acme' so I can use it as a checksum before sending the request.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha256-hex-latin1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA-256 hash of text interpreted as Latin-1 (ISO-8859-1) bytes rather than UTF-8, which matters for legacy systems, European character sets, or when matching checksums produced by Latin-1-aware software. Use the free sandbox endpoint (/v1/sandbox/digest-sha256-hex-latin1) first to validate your integration before paying $0.006 per call on this production endpoint.
Side effects
- Input text contains characters outside the Latin-1 range (codepoints > 255), causing encoding errors
- Missing required 'text' field returns a validation error
- Text exceeds 100,000 character limit returns a payload-too-large error
- Payment not provided or invalid USDC amount returns HTTP 402
- Key field missing or empty string returns a validation 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. |
