SHA3-224 Digest with Base64URL Encoding
x402
SHA3-224 Digest with Base64URL Encoding is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-28).
Computes a SHA3-224 cryptographic hash of input text and returns it encoded as base64url, with no network calls or LLM involved.

How this service works
Call when an agent needs a sha3-224 digest of text, encoded as base64url. No network and no LLM. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-224-base64url first.
Output
Returns a SHA3-224 cryptographic digest of the submitted text, encoded as a base64url string. The output is deterministic, compact, and URL-safe, suitable for use as checksums, fingerprints, or identifiers.
Example use cases
Fingerprinting document content for deduplication
“Hash this document text using SHA3-224 and give me the base64url digest so I can use it as a deduplication key: 'The quick brown fox jumps over the lazy dog.'”
Generating a URL-safe content checksum
“I need a URL-safe checksum of the string 'user:42:session:abc123' — can you run SHA3-224 on it and return the base64url result?”
Tamper detection for stored config values
“Compute a SHA3-224 base64url digest of this config string so I can store it alongside the config and detect any future modifications: 'max_retries=5;timeout=30;mode=strict'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-224-base64url?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need SHA3-224 (not SHA2, MD5, or BLAKE2) output encoded as base64url (not hex or base32), for use cases like URL-safe fingerprints, compact checksums, or when downstream systems require that exact combination of algorithm and encoding. Use the sandbox endpoint (POST /v1/sandbox/digest-sha3-224-base64url) for testing before paying.
Side effects
- Empty or missing text field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or invalid API key results in authentication failure
- Malformed request body returns a 400 bad request 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. |
