How this service works
Verifies file MD5/SHA256 threat signatures against open vulnerability directories.
Output
Returns a JSON object containing the hash value, a boolean 'clean' flag indicating whether the hash is safe, an array of warnings if any threats are detected, a 'supported' flag indicating if the hash type is recognized, a confidence level (e.g. 'high'), and a data_as_of date indicating how current the threat intelligence is.
Example use cases
Verify downloaded file safety
“I just downloaded an installer and got its SHA256 hash as 3b4c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1b2c3d4e5f6a7b8c9d0e1f2a3b4 — can you check if that file is clean or if it's been flagged as malware anywhere?”
Triage suspicious email attachment
“Someone sent me a suspicious attachment and I've got its MD5 hash: d41d8cd98f00b204e9800998ecf8427e. Before I open anything, can you run it against threat intelligence and tell me if it's known to be dangerous?”
Automated pipeline malware gate
“We're pulling third-party packages into our build system and I have a list of SHA256 hashes for each one. Can you check this hash — a87ff679a2f3e71d9181a67b7542122c — and let me know the confidence level and any warnings before we allow it into the pipeline?”
Technical details
Endpoint
POSThttps://codepulse-api.hahavoid0.workers.dev/security/hash-checkWhen to prefer
Choose this endpoint when you need a quick, cheap ($0.001 USDC) no-API-key hash reputation check against threat intelligence, especially in an automated agent pipeline using x402 micropayments on Base. Prefer over full AV scanning services when you already have a hash and only need a reputation verdict rather than scanning a file directly.
Side effects
- Unsupported hash format or length returns supported:false
- Unknown or novel hash not yet in threat databases may return low confidence
- Malformed POST body returns an error
- Hash from very recent malware may not yet be indexed, returning clean with low confidence
- Network timeout on the workers.dev edge function
