How this service works
Call when an agent needs a blake2b512 digest of text, encoded as base32. No network and no LLM. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/digest-blake2b512-base32 first.
Output
Returns a BLAKE2b-512 cryptographic digest of the provided text, encoded as an uppercase Base32 string. No network calls or LLM inference are involved; the computation is deterministic and reproducible given the same input.
Example use cases
Content deduplication fingerprinting
“Hash this article text using BLAKE2b-512 and return the Base32 digest so I can use it as a deduplication key: 'The quick brown fox jumps over the lazy dog. This is the full article body.'”
Keyed integrity check for data pipeline
“Compute a keyed BLAKE2b-512 digest of the string 'user_id=42,action=purchase,amount=99.99' using the key 'my-secret-pipeline-key', and give me the Base32-encoded result.”
Deterministic content ID generation
“I need a Base32-encoded BLAKE2b-512 hash of this JSON payload so I can use it as a unique content identifier: '{"event":"signup","email":"alice@example.com","ts":1700000000}'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-blake2b512-base32?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a BLAKE2b-512 hash (not SHA-256, SHA-3, or BLAKE2s) and require Base32 output encoding (not hex or Base64). It is ideal for systems that use Base32-friendly identifiers, case-insensitive hash strings, or interoperability with Base32-native protocols. Prefer the free sandbox endpoint /v1/sandbox/digest-blake2b512-base32 for testing before incurring the $0.008 USDC charge.
Side effects
- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Key exceeding 512 characters is rejected
- Malformed JSON body returns a 400 error
- Payment failure (x402) if USDC balance is insufficient
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. |
