SHA-1 Hex Digest
x402
SHA-1 Hex Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-30).
Computes the SHA-1 hash of a given text string and returns it as a lowercase hexadecimal digest

How this service works
Call when an agent needs a sha1 digest of text, encoded as hex. No network and no LLM. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/digest-sha1-hex first.
Output
Returns the SHA-1 hash of the input text encoded as a lowercase hexadecimal string (40 characters). The response is deterministic — the same input always yields the same digest. No network calls or LLM inference are involved in the computation.
Example use cases
Deduplication fingerprinting for content pipeline
“I need to deduplicate articles before storing them — can you compute the SHA-1 hex digest of this article body so I can use it as a unique fingerprint?”
Cache key generation from request payload
“Generate a SHA-1 hex hash of this JSON string so I can use it as a cache key: '{"userId":42,"action":"export"}'.”
Legacy system compatibility checksum
“Our legacy system expects SHA-1 hex checksums for file contents. Can you compute the SHA-1 hex digest of this text block I'm about to paste?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha1-hex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a SHA-1 hex digest specifically — for example, for legacy system compatibility, Git object IDs, or HTTP ETags that require SHA-1 format. If SHA-2 (SHA-256) or BLAKE2 suffices, prefer those stronger alternatives. Use this over running local code when the agent environment lacks execution capability or when a deterministic, auditable third-party hash is needed. Try the free sandbox endpoint POST /v1/sandbox/digest-sha1-hex first to avoid the $0.005 USDC cost.
Side effects
- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or invalid API key causes authentication failure
- Payment failure (insufficient USDC balance) results in 402 response
- Malformed request body returns 400 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. |
