x402
SHA-512/224 Digest (Base64) — agentshelf.syntexa.ch is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-01).
Computes a SHA-512/224 cryptographic hash of input text and returns the digest encoded as base64, with no network calls or LLM involvement.

How this service works
Call when an agent needs a sha512-224 digest of text, encoded as base64. No network and no LLM. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-224-base64 first.
Output
Returns a base64-encoded SHA-512/224 digest string computed from the provided input text. The output is a deterministic, fixed-length hash suitable for integrity checks, fingerprinting, or use as a compact identifier.
Example use cases
Integrity fingerprint for log entries
“Take this log line — 'ERROR 2024-06-01T12:00:00Z service crashed' — and give me its SHA-512/224 digest in base64 so I can use it as a tamper-evident fingerprint.”
Deterministic ID from user input
“I need a short, stable base64 hash of the string 'user:alice@example.com:2024' using SHA-512/224 to use as a deterministic record ID.”
Checksum for config file contents
“Hash this config snippet using SHA-512/224 and return it base64-encoded so I can store a compact checksum alongside the file: 'host=localhost port=5432 db=myapp'.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha512-224-base64?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a compact, secure cryptographic hash of text using the SHA-512/224 algorithm and want the result base64-encoded — especially when you want to avoid running your own crypto library, need a serverless/stateless hash with no external network calls, or are operating in an agent pipeline that pays per-use via USDC. Prefer the free sandbox endpoint (/v1/sandbox/digest-sha512-224-base64) for testing before using the paid version.
Side effects
- Text or key exceeding maximum length (100,000 or 512 characters respectively) returns a validation error
- Empty text or key field returns a validation error
- Malformed request body returns a 400-level error
- Payment failure or insufficient USDC balance returns a 402 Payment Required 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. |
