SHA3-512 Base64 Digest
x402
SHA3-512 Base64 Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-01).
Computes a SHA3-512 cryptographic hash of input text and returns it encoded as base64, with no network calls or LLM involved.

How this service works
Call when an agent needs a sha3-512 digest of text, encoded as base64. No network and no LLM. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-512-base64 first.
Output
Returns a base64-encoded SHA3-512 digest string of the provided input text. The computation is deterministic and performed without any external network calls or LLM processing, guaranteeing consistent results for the same input.
Example use cases
Content integrity fingerprinting
“I need to generate a SHA3-512 hash of this contract text so I can verify it hasn't changed later — please hash it and give me the base64 digest: 'This agreement is entered into as of January 1, 2025 between Acme Corp and Widget LLC.'”
Deterministic ID generation from text
“Can you compute a SHA3-512 base64 digest of the string 'user:alice@example.com:2025-01-01' so I can use it as a unique, collision-resistant identifier?”
Audit log tamper detection
“Take this log entry and produce a SHA3-512 base64 hash I can store alongside it for tamper detection: 'action=delete resource=file.txt user=bob timestamp=1735689600'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-512-base64?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a strong, modern cryptographic hash (SHA3-512) of text returned in base64 format without any local computation. It is ideal when your runtime environment cannot execute hashing libraries, when you need a verified deterministic hash from a neutral third party, or when you require the SHA3 (Keccak) family rather than SHA2. Prefer the free sandbox endpoint (/v1/sandbox/digest-sha3-512-base64) for testing; use this paid endpoint for production workloads.
Side effects
- Empty or missing text field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or empty key field causes a request error
- Malformed JSON body returns a 400 error
- Insufficient USDC balance or payment failure blocks the request
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. |
