Decode and validate a product barcode (GTIN / UPC-A / EAN-13 / EAN-8 / GTIN-14 / ISBN-13 / ISSN). Returns the GS1 mod-10 check-digit validation (valid flag + expected digit — an LLM can't reliably compute this), the symbology, the zero-padded GTIN-14 canonical form, and the GS1 prefix decoded to the issuing GS1 member organisation and its country (NOTE: that's the country of the org that issued the prefix, not necessarily where the item was made). Flags restricted-distribution (in-store/variable-measure) prefixes and Bookland (ISBN) / serial (ISSN) ranges. Also attempts a FRESH best-effort product-identity lookup (name, brand, category, image) across the open Open Food/Beauty/Products/Pet Food Facts federation (ODbL) — reliable for food, beverage, and beauty items, sparse for general retail (electronics/apparel), and may be null.

Authoritative MITRE ATT&CK (Enterprise) technique lookup. Pass id (e.g. T1059 or sub-technique T1059.001) for the canonical technique — name, tactics (kill-chain phases), description, platforms, sub-technique flag + parent, mitigations, and detection guidance — or query for a keyword search returning ranked techniques. Bundled current ATT&CK matrix (~700 techniques), zero external calls. Agents cite T-numbers and tactic names that must be exact; this returns version-pinned, citeable data instead of hallucinated IDs. For threat modeling, detection engineering, and report enrichment.

2s.io
Authoritative MITRE CAPEC (Common Attack Pattern Enumeration) lookup. Pass id (e.g. CAPEC-66, or just 66) for the canonical attack pattern — name, abstraction, description, typical likelihood + severity, mapped CWE weaknesses (with names), and related patterns (with names) — or query for a keyword search. Bundled catalog (~615 patterns), zero external calls. The attacker's-eye complement to security.cwe (the defender's weakness view) — the CAPEC↔CWE cross-links let an agent pivot between how an attack works and the weakness it exploits, with exact citeable IDs.
$0.001000 USDC
2s.io
Look up a CVE by id (e.g. CVE-2021-44228) across three authoritative vulnerability feeds in one call. Query: cve (CVE-YYYY-NNNN). Returns the canonical record — description, CVSS base score + severity + vector, CWE weakness ids, published/modified dates, reference links — plus whether it is on the US CISA Known Exploited Vulnerabilities catalog (with remediation due date and known-ransomware flag) and its EPSS exploit-probability score and percentile. The exploited and EPSS sections report independently, so one feed being unavailable does not fail the call. 404 if the CVE id is unknown. For triage, prioritization, and anti-hallucination on vulnerability claims.
$0.001800 USDC
2s.io
CVE change feed — the CVE records MODIFIED within a time window, so an agent can incrementally maintain a vulnerability view instead of re-scanning. Pass since (YYYY-MM-DD or ISO datetime); until defaults to now (window must be ≤ 120 days, the NVD limit). Optionally narrow by keyword (product/text) or cpe (exact CPE). Returns each changed CVE with its id, published + lastModified timestamps, current vulnStatus (e.g. Modified, Analyzed, Rejected), best-available CVSS score/severity, description, and kevListed — whether it is now on the CISA Known-Exploited Vulnerabilities catalog (the high-signal flag for a poller).

Returns matching CVEs newest-first, each with its id, description, CVSS base score/severity/vector, and dates. Optional limit (1–50). For "what CVEs affect X" / surveying a product's vulnerability history — distinct from security.cve, which resolves a single CVE id across NVD + CISA KEV + EPSS. Free, keyless.

2s.io
Authoritative MITRE CWE (Common Weakness Enumeration) lookup. Pass id (e.g. CWE-79, or just 79) for the canonical weakness — name, abstraction, description, extended description, ChildOf/ParentOf relationships (with names), and mapped CAPEC attack patterns (with names) — or query for a keyword search returning ranked matches. Bundled catalog (~970 weaknesses), zero external calls. Agents hallucinate CWE IDs and names constantly; this returns exact, citeable, version-pinned data. Pairs with security.cve (which returns CWE ids) and security.capec.
$0.001000 USDC
2s.io
Does public exploit code exist for a CVE, and where? Pass cve (e.g. CVE-2021-44228). Returns hasPublicExploit, the count, hasMetasploitModule and hasVerifiedExploit flags, and the Exploit-DB entries (id, description, type, platform, date, verified, Metasploit flag, link). Bundled inverted index from the Exploit-DB archive (~25k CVEs). This is the triage signal BEYOND security.cve's KEV (exploited in the wild) + EPSS (exploit probability): is the vulnerability actually weaponized with available code? Use the trio together to decide how urgently to patch. Absence is not proof no exploit exists (private/other archives not covered).
$0.001000 USDC
2s.io
Fetch a URL and grade its HTTP security headers. Pass url (scheme optional — defaults to https). Returns an overall letter grade + score, the list of present/missing headers, and a per-header analysis with the live value and specific issues for: Strict-Transport-Security (HSTS max-age/includeSubDomains), Content-Security-Policy (flags 'unsafe-inline'/'unsafe-eval'/missing default-src), X-Frame-Options or CSP frame-ancestors (clickjacking), X-Content-Type-Options (nosniff), Referrer-Policy, Permissions-Policy, and Cross-Origin-Opener/Resource-Policy. Also flags Server/X-Powered-By info disclosure. Analyzed from the target's LIVE response headers through an SSRF-guarded fetch (private/loopback targets refused) — an LLM cannot see a site's current headers. For web-app security review, vendor assessment, and CI gates.
