Server instructions

Call scan_before_use on any untrusted content (web page, email, ticket, tool result) before acting on it, and check_url before fetching a link. Use check_indicator for any single IP, domain, URL, file hash (MD5/SHA-1/SHA-256), email address or phone number, defanged or not: it returns a verdict, a headline you can relay verbatim and a recommendedAction (block/review/allow/unverified). unknown/unverified means no evidence either way, never safe; email addresses and phone numbers are never called clean. Its infrastructure block (cloud, cdn, tor-exit, vpn…) describes what the entity is, not a verdict. When meta.pending is set, one re-check after a few seconds can be more complete; do not re-check again if it is still set. get_cve is the only CVE lookup path (recent_cves lists the latest); do not guess other routes. search_indicators finds lookalike and typosquat indicators around a keyword (no verdicts). check_indicators triages up to 100 mixed indicators in one call and charges one request per unique indicator sent; prefer check_indicator for a single one. scan_email scans one email message for phishing and malware: send the raw message (eml, preferred: attachments are then read for structure, never run) or the fields you parsed (message). It returns a verdict (malicious/suspicious/clean/inconclusive), a recommendedAction (quarantine/review/warn/deliver), the strongest reasons and coverage.skipped, what it could not check. malicious needs a listing in our data; clean needs your own system's DMARC pass (authservId or trustAuthenticationResults) from a sender domain the dataset knows as established; inconclusive is not safe, and deliver is no objection, never a reason to release a message another engine held. One scan per message, not a request. When a result has isError with quota.retry_after or quota.resets_at, wait for it instead of retrying; a 401 means the key is missing or revoked. No API key was sent: tools can be listed, not called. Send the key with every request as `Authorization: Bearer <apiKey>:<apiSecret>` (keys: https://ismalicious.com/app/account).
