SHA-224 Base64 Digest
x402
SHA-224 Base64 Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.008/call, status unknown (last checked 2026-10-01).
Computes a SHA-224 cryptographic hash of input text and returns it encoded as a base64 string, with no network or LLM calls involved.

How this service works
Call when an agent needs a sha224 digest of text, encoded as base64. No network and no LLM. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/digest-sha224-base64 first.
Output
Returns a base64-encoded SHA-224 digest (a 224-bit hash encoded as a ~40-character base64 string) of the provided input text. The result is deterministic, compact, and suitable for checksums, fingerprinting, or deduplication keys.
Example use cases
Content fingerprinting for deduplication
“Hash this article body with SHA-224 and give me the base64 digest so I can check if we've already indexed this piece of content: 'The quick brown fox jumps over the lazy dog.'”
Data integrity checksum generation
“Generate a SHA-224 base64 digest for this config value so I can store a tamper-evident checksum alongside it: 'db_host=prod.db.example.com;port=5432'”
Deterministic ID creation from text
“I need a short, stable identifier derived from this user-supplied string — can you compute its SHA-224 hash as base64? The string is 'user:alice@example.com:2024-01-15'.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha224-base64?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a SHA-224 specifically (not SHA-256 or SHA-512), and want the output pre-encoded as base64 rather than hex. It is a pure compute operation with no external dependencies, making it fast and deterministic. Prefer the free sandbox endpoint (/v1/sandbox/digest-sha224-base64) for testing before paying $0.008 USDC per call in production.
Side effects
- Empty or missing text field returns validation error
- text exceeding 100,000 characters is rejected
- Missing or invalid API key returns authentication error
- Malformed JSON body returns parse 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. |
