stackfacts_eol_product | List every release cycle of a product (Node.js, Python, Ubuntu…) and if it is still supported: EOL (end-of-life) date, support status, LTS, latest version. |
stackfacts_eol_cycle | Check if a version is still supported (is python 3.12 still supported?): one release cycle, its EOL (end-of-life) date, support status, LTS, latest patch. |
stackfacts_eol_check | Check runtimes and OS versions for EOL: is each still supported? Up to 50 product@version pairs, end-of-life date, support status; unknowns get suggestions. |
stackfacts_eol_image | Check a container image for EOL: is node:18-alpine still supported? Maps its runtime, Java and base OS to end-of-life date and support status. |
stackfacts_eol_snapshot | Download the signed EOL (end-of-life) snapshot (endoflife.date, MIT): support status of every product and cycle, still supported or not, plus its manifest. |
stackfacts_kev_lookup | Check if a CVE is actively exploited (CISA KEV): in_kev, date added, remediation due date, required action and known ransomware use. |
stackfacts_kev_check | Check up to 100 CVEs at once against CISA KEV (known exploited vulnerabilities); returns in_kev and the KEV details for each one. |
stackfacts_kev_changes | List CVEs added to, removed from or changed in CISA KEV since a snapshot_id, so an agent can poll for newly exploited vulnerabilities. |
stackfacts_kev_snapshot | Download the full signed CISA KEV snapshot: every known exploited vulnerability, with a manifest to verify the sha256 and signature. |
stackfacts_models_lookup | Get an LLM model's price per million tokens (input, output, cached), context window, max output, capabilities and model deprecation date. |
stackfacts_models_estimate | Estimate the USD cost of an LLM call from input, output and cached token counts, exact to the micro-dollar, with the price lines used. |
stackfacts_models_cheapest | Find the cheapest model with tools and 128k context, or any limits you set: ranks the 10 cheapest LLMs by blended price per million tokens. |
stackfacts_models_changes | List LLM models added, removed or changed (price per million tokens, context window, model deprecation date) since a snapshot_id. |
stackfacts_models_watch | Check LLMs for what changed since your last call: changed records (with today's price and limits), removals, deprecated or soon deprecated, with snapshot dates. |
stackfacts_models_snapshot | Download the full signed LLM model catalogue (LiteLLM + models.dev, MIT): prices, limits and capabilities, with a verifiable manifest. |
stackfacts_stack_check | Check dependencies, runtimes and OS versions in one call: OSV for up to 50 purls, EOL for 50 product@version pairs, CISA KEV hits, suggestions for unknowns. |
stackfacts_osv_check | Check dependencies or a lockfile for vulnerable and malicious packages: up to 50 purls, or a package-lock, yarn.lock, requirements.txt or poetry.lock, on OSV. |
stackfacts_preflight | Call before installing a package an LLM suggested: one npm, PyPI or purl version against OSV, CISA KEV and EOL data. Returns ok, warn or block with reasons. |
stackfacts_cve_lookup | Get any CVE: CISA KEV entry, CVSS score and patch priority, plus every OSV advisory aliased to it, with affected packages and fixed versions. |
stackfacts_cwe_lookup | Get one MITRE CWE weakness by id (79 or CWE-79): name, status, description and MITRE link. From the CWE catalogue (v4.20); MITRE notice on every answer. |
stackfacts_technique_lookup | Get one technique by id (T1055.011): name, tactics, platforms, description, mitigations, detection, data sources and link. MITRE ATT&CK v20.0; credited. |
stackfacts_capec_lookup | Get one MITRE CAPEC attack pattern by id: severity, likelihood, prerequisites, mitigations, related CWE and ATT&CK ids and MITRE link. |
stackfacts_domain_lookup | Get the public suffix, registrable domain and subdomain of a host name from the Mozilla Public Suffix List, with the matching rule and section. |
stackfacts_port_lookup | Get the IANA service name, transport, description and reference for a port number from the IANA Service Name and Transport Protocol Port Number Registry. |
stackfacts_control_lookup | Get one NIST SP 800-53 Rev 5 security control or enhancement by id (AC-2, AC-2(1)): title, statement, guidance, related controls and status. |
stackfacts_bcp47_lookup | Get an IANA language tag (en-AU, zh-Hant) part by part: type, description, scope, deprecation and preferred value from the Language Subtag Registry. |
stackfacts_tz_lookup | Get an IANA time zone (Europe/Berlin) or alias: current UTC offset, abbreviation, DST summary and backward-compatible names from tzdata. |
stackfacts_package_card | Get an npm or PyPI package's latest version, publish dates, deprecation or yank, SPDX licence, repository and runtime range. |
stackfacts_license_check | Call before adding a dependency: check SPDX licences or packages against your project licence and use, with a compatibility verdict per item. |
stackfacts_cve_prioritize | Call before patching: rank up to 100 CVEs by CISA KEV status, then CVSS base score. |
stackfacts_cve_search | Find CVEs by keyword or package name in CISA KEV and OSV (not all of NVD), with KEV status and CVSS v3 where an OSV advisory has one. |
stackfacts_package_preflight | Call before installing an npm or PyPI package: latest or given version, licence, OSV vulns, CISA KEV CVEs, deprecation or yank. Returns ok, caution or block. |
stackfacts_upgrade_delta | Check moving an npm or PyPI package from one version to another: advisories fixed or introduced, KEV, licence, runtime. Returns go, review or no_go. |
stackfacts_lockfile_diff | Check npm or PyPI purl lists or raw lockfiles: upgrades judged on advisories, KEV, licence; same version, other hash = hash_mismatch. Returns go, review, no_go. |
stackfacts_stack_watch | Check dependencies, runtimes and OS versions for what changed since your last call: EOL passed or near, new OSV advisories, new CISA KEV hits. Returns a token. |
stackfacts_preview | Preview a dataset for free: sample end-of-life products, newest CISA KEV entries, LLM prices, a package card or a licence verdict. |
stackfacts_try | Try a paid answer for free on a fixed example: nodejs end-of-life cycles, CVE-2021-44228 in CISA KEV, or openai/gpt-4o prices. |
stackfacts_index | List the valid ids for free: end-of-life product names and aliases, or LLM provider/model ids, so a paid call never misses. |
stackfacts_validate | Validate an id for free. Privacy: only an unknown EOL id is logged (access log, miss field); a 400 logs the input name, never its value. No other id is stored. |
stackfacts_manifest | Get the signed manifest of a dataset's latest snapshot for free: snapshot_id, sha256, record count, source, licence and signature. |
stackfacts_keys | Get the Ed25519 public keys (JWK) that verify the signature on every answer and snapshot manifest. |
