How this service works
Call when an agent needs a sha512-224 digest of text, encoded as hex. No network and no LLM. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-224-hex first.
Output
Returns a lowercase hexadecimal string representing the SHA-512/224 digest of the input text. The output is a deterministic 56-character hex string (224 bits) uniquely identifying the input content.
Example use cases
File integrity checksum generation
“I need the SHA-512/224 hex hash of this config file content so I can verify it hasn't been tampered with: 'server_host=localhost;port=8080;debug=false'”
Message deduplication fingerprinting
“Compute the SHA-512/224 hex digest of this log entry so I can use it as a deduplication key: '2024-01-15T10:23:45Z ERROR Connection timeout after 30s on host db-primary'”
Password pre-hashing before storage
“Hash this passphrase using SHA-512/224 and give me the hex output: 'correct horse battery staple 42'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha512-224-hex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a compact SHA-512/224 hash in hexadecimal format specifically — it is faster and produces a shorter digest than full SHA-512 while retaining strong collision resistance. Prefer this over SHA-256 hex when you need the SHA-512/224 standard specifically for compliance or interoperability. Use the free sandbox endpoint POST /v1/sandbox/digest-sha512-224-hex for testing before incurring the $0.001 USDC cost. No external network calls or LLM inference are involved, making this deterministic and fast.
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 request body returns 400 error
- Payment failure or insufficient USDC balance returns 402
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. |
