SHAKE-256 Digest with Base32 Encoding
x402
SHAKE-256 Digest with Base32 Encoding is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.008/call, status unknown (last checked 2026-10-01).
Computes a SHAKE-256 cryptographic hash of input text and returns the digest encoded in Base32 format.

How this service works
Call when an agent needs a shake256 digest of text, encoded as base32. No network and no LLM. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/digest-shake256-base32 first.
Output
A Base32-encoded string representing the SHAKE-256 digest of the submitted text. The response is a deterministic, fixed-output hash that can be used for integrity checking, deduplication, or fingerprinting.
Example use cases
Data integrity fingerprint for a payload
“I need a SHAKE-256 digest of this JSON payload encoded in base32 so I can use it as a tamper-evident fingerprint: '{"orderId":"abc123","amount":99.99}'”
Content deduplication by hash
“Compute a base32-encoded SHAKE-256 hash of the following article text so I can use it to detect duplicates in my content database: 'The quick brown fox jumps over the lazy dog repeatedly.'”
Keyed hash for cache key generation
“Generate a SHAKE-256 base32 digest of the string 'user:42:profile:v3:en' using the key 'my-cache-namespace' — I want to use it as a compact, fixed-length cache key.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-shake256-base32?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHAKE-256 (XOF/extendable-output) hash and the consumer of the digest expects Base32 encoding (e.g., case-insensitive systems, certain identifier schemes). Prefer the free sandbox endpoint (/v1/sandbox/digest-shake256-base32) for testing. Use the SHAKE-128 variant if you need lower computational cost and the shorter digest strength is acceptable. Use the hex-encoded SHAKE-256 sibling if your system expects hexadecimal output instead of Base32.
Side effects
- Empty or missing 'text' field returns a validation error
- 'text' field exceeding 100,000 characters is rejected
- Missing or empty 'key' field may cause a validation error depending on whether it is required
- Invalid JSON body returns a 400-level error
- Payment not included or insufficient USDC (not $0.008) results in a 402 Payment Required response
- Network or server error returns a 5xx response
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. |
