x402
SHA3-224 Digest to Base64url (Raw Hex Input) is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-29).
Computes a SHA3-224 hash of hex-encoded bytes and returns the digest encoded as base64url

How this service works
Call when an agent needs a sha3-224 digest of hex bytes, encoded as base64url. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-224-base64url-rawhex first.
Output
Returns a SHA3-224 digest of the input hex bytes, encoded as a base64url string. The digest is 28 bytes (224 bits) long, represented compactly in URL-safe base64 without padding issues.
Example use cases
Integrity fingerprint for binary payload
“I have a binary payload represented as hex bytes '0a1b2c3d4e5f' — can you compute the SHA3-224 digest of it and return it in base64url format so I can use it as a fingerprint?”
Cryptographic commitment scheme
“I need to create a SHA3-224 commitment over this raw hex data 'deadbeef0102030405' and encode the result as base64url to embed in a smart contract call.”
Verify hash of hex-encoded file chunk
“I've chunked a file and have this hex-encoded segment 'f0e1d2c3b4a59687' — hash it with SHA3-224 and give me the base64url digest so I can compare it against my reference hash table.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-224-base64url-rawhex?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to hash raw binary data expressed as hexadecimal and require the output in base64url encoding specifically using the SHA3-224 algorithm. Prefer this over the free sandbox equivalent (/v1/sandbox/digest-sha3-224-base64url-rawhex) only when the sandbox is unavailable or rate-limited. Choose this over SHA-256 or SHA-512 variants when SHA3-224 is specifically required by a protocol or standard.
Side effects
- Invalid hex string input (odd length or non-hex characters) returns an error
- Input text exceeds 100,000 character limit
- Missing required 'text' field returns a validation error
- Payment of $0.003 USDC not provided or fails — HTTP 402 response
- Malformed request body returns 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. |
