File Hash Reputation Lookup via CIRCL HashlookUp
x402
File Hash Reputation Lookup via CIRCL HashlookUp is a paid API for AI agents from api.agentstools.dev, paid per call via x402, $0.008/call, status unknown (last checked 2026-09-15).
Looks up a file hash (MD5, SHA1, or SHA256) against CIRCL hashlookup to return known-file status, trust score, and file metadata for SOC/DFIR triage.

How this service works
File-hash reputation and known-file context for a SOC or DFIR agent. Give an md5, sha1 or sha256 hash and get CIRCL hashlookup known-file status, a hashlookup trust score and file metadata (name, size, mimetype, source, database), plus malware family when a licensed feed is enabled. A known distribution or system file lowers the alert priority; an unknown hash is not itself evidence of malice. Indicators, not a guarantee.
Output
Returns CIRCL hashlookup known-file status (found/not found), a numeric trust score, and file metadata including file name, size, MIME type, source database, and malware family if a licensed feed is enabled. An unknown hash is flagged as such without implying malice.
Example use cases
Example prompt
“Can you check this SHA256 hash — 3395856ce81f2b7382dee72602f798b642f14d8b2b9cdd95ea2f80e6b8b7c4f6 — and tell me if CIRCL hashlookup recognizes it as a known file, what its trust score is, and whether it's associated with any malware family?”
Technical details
Endpoint
GEThttps://api.agentstools.dev/threat/hashWhen to prefer
Use this endpoint during SOC alert triage or DFIR investigations when you have a file hash and need to quickly determine whether it belongs to a known benign distribution or system file, reducing false-positive alert load. Prefer this over full sandbox detonation when a hash reputation check is sufficient to deprioritize an alert. Best for workflows that handle MD5, SHA1, or SHA256 hashes and need CIRCL hashlookup's trust scoring specifically.
Side effects
- Hash not found in CIRCL hashlookup database — not evidence of malice, just unknown
- Invalid hash format (wrong length or non-hex characters) returns a validation error
- Hash provided as wrong type identifier (e.g. misidentified SHA1 as MD5) may yield no result
- Licensed malware feed not enabled — malware family field absent from response
- Rate limit or payment failure returns 402 or 429 status
