x402
SHA-512/256 Digest — Base64-Encoded, Latin1 Input is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.007/call, status unknown (last checked 2026-09-29).
Computes a SHA-512/256 cryptographic hash of a latin1-encoded byte string and returns it as a base64-encoded digest.

How this service works
Call when an agent needs a sha512-256 digest of latin1 bytes, encoded as base64. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-256-base64-latin1 first.
Output
Returns a base64-encoded SHA-512/256 digest string computed from the provided latin1-encoded input text, with no external network calls or LLM inference involved.
Example use cases
Data integrity fingerprint for latin1 content
“I need a SHA-512/256 checksum of this latin1-encoded document text — 'café résumé naïve' — returned as base64 so I can verify it hasn't been tampered with.”
Deterministic ID generation from latin1 string
“Generate a compact, deterministic SHA-512/256 base64 hash of the latin1 string 'señor García, año 2024' so I can use it as a unique identifier.”
Keyed hash for latin1 payload signing
“Compute a SHA-512/256 base64 digest of the latin1 text 'montréal réservation' using the key 'my-secret-key' so I can sign this payload.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha512-256-base64-latin1?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need a SHA-512/256 (truncated SHA-512) hash of latin1-encoded bytes returned as standard base64. Choose it over SHA-256 when you want the security margin of SHA-512 with a 256-bit output, and over hex-encoded variants when base64 compactness is required. If an unpaid sandbox version is available at /v1/sandbox/digest-sha512-256-base64-latin1, prefer that first.
Side effects
- Text contains non-latin1 characters that cannot be encoded — returns an error
- Text or key exceeds maximum length (100,000 or 512 chars respectively) — validation error
- Empty text or key provided — rejected by minLength constraint
- Payment not attached or insufficient — 402 Payment Required response
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. |
