x402
SHA-384 Hex Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-01).
Computes a SHA-384 cryptographic hash of input text and returns it as a hexadecimal-encoded string.

How this service works
Call when an agent needs a sha384 digest of text, encoded as hex. No network and no LLM. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/digest-sha384-hex first.
Output
A hex-encoded SHA-384 digest string (96 hex characters) of the submitted text. The computation is deterministic and performed without any network calls or LLM inference.
Example use cases
Integrity fingerprint for file content
“I need a SHA-384 hex digest of this file content so I can verify it hasn't been tampered with: 'BEGIN CERTIFICATE MIIBIjANBgkqhkiG9w...'”
Deduplicate records by content hash
“Hash this JSON record with SHA-384 so I can use the hex digest as a deduplication key: '{"user":"alice","action":"login","ts":1718000000}'”
Audit log entry fingerprinting
“Compute a SHA-384 hex digest of this audit log line so I can store it as a tamper-evident checksum: 'user=bob action=delete resource=invoice-4421 time=2024-06-10T14:32:00Z'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha384-hex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a SHA-384 hash in hexadecimal format specifically, with no side effects, no external network calls, and deterministic output. It is ideal for data integrity verification, deduplication keys, or audit fingerprinting where SHA-384 strength (stronger than SHA-256) and hex encoding are required. Prefer the free sandbox endpoint (/v1/sandbox/digest-sha384-hex) for testing before using this paid version.
Side effects
- Text input missing or empty (validation error)
- Text exceeds 100,000 character limit (payload too large)
- Payment not included or insufficient — endpoint requires exactly $0.003 USDC via x402 protocol
- Malformed JSON request body
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. |
