AgentShelf Content Hash (SHA-256 / MD5)
x402
AgentShelf Content Hash (SHA-256 / MD5) is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).
Computes a SHA-256 or MD5 hex digest of provided text, entirely server-side with no external network calls.

How this service works
Call when an agent needs a SHA-256 or MD5 hex digest of provided text. No network. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/content-hash first.
Output
Returns a hex-encoded hash string (SHA-256 or MD5) of the submitted text. No network calls are made; the result is deterministic and reproducible for identical inputs.
Example use cases
Deduplication fingerprint for documents
“Hash this document excerpt with SHA-256 so I can use it as a deduplication key: 'The quick brown fox jumps over the lazy dog.'”
MD5 checksum for legacy compatibility
“I need the MD5 hex digest of the string 'user:password123' — my legacy system expects MD5 checksums for comparison.”
Content integrity verification
“Compute the SHA-256 hash of this JSON payload so I can compare it against a known checksum and confirm nothing was tampered with: '{"order_id":"abc123","amount":49.99}'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/content-hash?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, deterministic SHA-256 or MD5 hex digest of text without setting up local crypto libraries. Especially useful in agent pipelines where only these two standard algorithms are needed and a tiny per-call cost ($0.001 USDC) is acceptable. For SHA-3 or BLAKE2 digests, use sibling endpoints on the same host. Always try the free sandbox endpoint (POST /v1/sandbox/content-hash) first if available.
Side effects
- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Invalid 'algorithm' value (anything other than 'sha256' or 'md5') returns a bad request error
- Payment failure (insufficient USDC balance or x402 protocol error) blocks the call
