SHA-224 Base64url Digest
x402
SHA-224 Base64url Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.009/call, status unknown (last checked 2026-10-01).
Computes a SHA-224 cryptographic hash of input text and returns it encoded as base64url, with no network or LLM dependency.

How this service works
Call when an agent needs a sha224 digest of text, encoded as base64url. No network and no LLM. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/digest-sha224-base64url first.
Output
Returns the SHA-224 digest of the input text encoded in base64url format (no padding, URL-safe characters). The response is a short deterministic string suitable for use in URLs, headers, or as a compact fingerprint.
Example use cases
Content integrity fingerprinting
“Hash this document body with SHA-224 and give me the base64url digest so I can use it as a fingerprint: 'This agreement is binding and effective as of January 1, 2025.'”
Generating deterministic URL-safe identifiers
“I need a stable, URL-safe identifier for this user email address — can you compute the SHA-224 base64url hash of 'alice@example.com'?”
Verifying message authenticity
“Compute the SHA-224 base64url digest of this payload so I can compare it against the expected checksum: '{"event":"purchase","amount":42.00}'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha224-base64url?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a SHA-224 hash specifically encoded as base64url (URL-safe, no padding) rather than hex or standard base64. It is ideal when downstream systems expect base64url-encoded digests — for example, in JWT or URL components. Prefer the free sandbox POST /v1/sandbox/digest-sha224-base64url first for testing; use this paid endpoint for production workloads requiring guaranteed availability.
Side effects
- Missing or empty 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or invalid 'key' field returns an authentication/authorization error
- Payment not completed (HTTP 402) if x402 payment is not resolved
- Non-UTF-8 or malformed input may cause a 400 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. |
