threat-hash-reputation
x402
threat-hash-reputation is a paid API for AI agents from payai.agentstools.dev, paid per call via x402, $0.008/call, status unknown (last checked 2026-09-14).
Looks up a file hash (MD5, SHA1, or SHA256) against CIRCL hashlookup to determine if it's a known file, returning a trust score, file metadata, and optional malware family classification.

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 whether the hash matches a known file in the CIRCL hashlookup database, a numeric trust score indicating confidence in the file's legitimacy, file metadata (name, size, MIME type, source, database), and optionally a malware family label if a licensed threat feed is enabled. An unknown hash does not automatically indicate malice.
Example use cases
Alert triage in SOC workflow
“We just detected a suspicious executable on one of our endpoints with SHA256 hash 3395856ce81f2b7382dee72602f798b642f14d3b7b4a85f2c2db5800f33c935 — can you check its CIRCL hashlookup reputation and tell me the trust score and file metadata so I know whether to escalate this?”
DFIR known-good file verification
“During our forensic investigation I found a file with MD5 hash 900150983cd24fb0d6963f7d28e17f72 — is this a known legitimate system or distribution file according to hashlookup, and what's its trust score?”
Malware family identification
“Our sandbox flagged a sample with SHA1 hash da39a3ee5e6b4b0d3255bfef95601890afd80709 — can you look up whether it's associated with any known malware family and give me the file context from the hash reputation feed?”
Technical details
Endpoint
GEThttps://payai.agentstools.dev/threat/hashWhen to prefer
Choose this endpoint when you need fast, structured hash-based file reputation for SOC triage or DFIR investigations and want CIRCL hashlookup's known-file status plus a trust score without building your own lookup pipeline. Best suited for single-hash lookups during alert triage where reducing false positives on known-good files is the goal. Prefer over generic threat intel APIs when the CIRCL provenance and hashlookup trust scoring model specifically matches your workflow.
Side effects
- Hash not found in database — returned as unknown status, not evidence of malice
- Invalid hash format (wrong length or non-hex characters) — request rejected
- Licensed feed not enabled — malware family field absent from response
- Network timeout or upstream CIRCL service unavailability
- Payment failure via x402 protocol
