Blake2s-256 + Base32 Digest of Hex Bytes
x402
Blake2s-256 + Base32 Digest of Hex Bytes is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.006/call, status unknown (last checked 2026-10-02).
Computes a BLAKE2s-256 hash of raw hex-encoded bytes and returns the result encoded as Base32.

How this service works
Call when an agent needs a blake2s256 digest of hex bytes, encoded as base32. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/digest-blake2s256-base32-rawhex first.
Output
Returns a Base32-encoded string representing the BLAKE2s-256 digest of the provided hex-encoded bytes. If a key is provided, the hash is keyed (BLAKE2s MAC); otherwise it is an unkeyed digest.
Example use cases
Integrity fingerprint for binary data
“I have some binary data represented as hex — '0a1b2c3d4e5f' — can you compute its BLAKE2s-256 digest and give me the result as a Base32 string so I can use it as a fingerprint?”
Keyed BLAKE2s MAC for authentication
“Generate a keyed BLAKE2s-256 hash of the hex bytes 'cafebabe1234abcd' using the key 'auth-token-42', and return it in Base32 format so I can use it as a message authentication code.”
Compact checksum for log archiving
“I need a compact Base32-encoded BLAKE2s-256 checksum of this raw hex payload 'f0e1d2c3b4a59687' to attach to a log entry for tamper detection — can you calculate that for me?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-blake2s256-base32-rawhex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a BLAKE2s-256 hash (not SHA-256, SHA-3, or BLAKE2b) of raw bytes that are provided as a hex string, and require the digest output in Base32 encoding. Prefer it over the free sandbox variant only when the sandbox is unavailable or rate-limited.
Side effects
- Invalid or non-hex characters in the 'text' field causing a 400 error
- Empty or missing 'text' field (minLength:1 violated)
- Key exceeding 512 characters causing a 400 validation error
- Payment failure or insufficient USDC balance resulting in a 402 response
- Malformed request body returning a parsing 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. |
