SHA-512 Digest — Base64URL Encoded, Latin1 Input
x402
SHA-512 Digest — Base64URL Encoded, Latin1 Input is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.006/call, status unknown (last checked 2026-10-19).
Computes a SHA-512 cryptographic hash of Latin1-encoded bytes from input text and returns the digest encoded as a Base64URL string.

How this service works
Call when an agent needs a sha512 digest of latin1 bytes, encoded as base64url. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-base64url-latin1 first.
Output
Returns a SHA-512 cryptographic digest of the input text interpreted as Latin1 bytes, encoded as a Base64URL string (no padding, URL-safe characters). The response is deterministic: the same input always produces the same hash.
Example use cases
Checksum verification of binary-safe content
“I need to verify the integrity of this Latin1-encoded payload — can you give me its SHA-512 Base64URL digest so I can compare it to the one on the server? The text is 'caf\xe9 menu data'.”
Generating URL-safe fingerprints for signed tokens
“Generate a SHA-512 Base64URL fingerprint of this Latin1 string 'user:johndoe\xff\xfe' so I can use it as a URL-safe signature in a redirect link.”
Deduplication key for Latin1 encoded records
“I have a Latin1-encoded database record — 'Ren\xe9 Descartes, born 1596' — and I need a SHA-512 Base64URL hash to use as a unique deduplication key.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha512-base64url-latin1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA-512 hash of text that must be treated as Latin1 (ISO-8859-1) byte sequences — not UTF-8 — and the output must be Base64URL encoded for use in URLs, JWTs, or other contexts requiring URL-safe characters. Use this instead of UTF-8 variants when your input is binary data or legacy Latin1-encoded content, and instead of hex or Base64 variants when URL safety matters.
Side effects
- Input text contains characters outside Latin1 range (code points > 255), causing encoding failure
- Missing required 'text' field returns a validation error
- Text exceeds 100,000 character limit returns a payload-too-large error
- Payment of exactly $0.006 USDC not received results in a 402 Payment Required response
- Network timeout or service unavailability returns a 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. |
