How this service works
Call when an agent needs a shake256 digest of text, encoded as base64. No network and no LLM. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/digest-shake256-base64 first.
Output
A base64-encoded string representing the SHAKE256 (XOF) digest of the provided input text, computed locally without any network calls or LLM inference.
Example use cases
Content integrity fingerprinting
“I need a SHAKE256 base64 digest of this JSON payload so I can verify it hasn't been tampered with: '{"user":"alice","action":"transfer","amount":500}'”
Deterministic token generation
“Hash the string 'session:user42:2024-06-01T12:00:00Z' with SHAKE256 and give me the base64 output so I can use it as a unique session token.”
Deduplicate text documents
“Compute a SHAKE256 base64 hash of this article text so I can check whether we've already indexed this exact document before storing it.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-shake256-base64?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need a SHAKE256 (extendable-output function) digest encoded as base64. Prefer this over SHA-256 or SHA-3 variants when SHAKE256's variable-length XOF properties are required, or when interoperating with systems that expect base64 encoding specifically. Use the free sandbox endpoint (/v1/sandbox/digest-shake256-base64) for testing before paying the $0.006 USDC fee.
Side effects
- Missing or empty 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or empty 'key' field may return an error if required
- Payment of exactly $0.006 USDC must be provided; insufficient funds result in a 402 response
- Malformed request body returns a 400-level 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. |
