Tools
| Tool | Description | Behaviour |
|---|---|---|
| stackfacts_cve_lookup | Get any CVE: its CISA KEV entry, if exploited, plus every OSV advisory aliased to it, with affected packages (purls), fixed versions and CVSS. | Read-only |
| stackfacts_eol_check | Check dependencies, runtimes and OS versions for EOL: is each still supported? Up to 50 product@version pairs to cycle, end-of-life date and support status. | Read-only |
| 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. | Read-only |
| 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. | Read-only |
| 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. | Read-only |
| 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. | Read-only |
| 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. | Read-only |
| 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. | Read-only |
| 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. | Read-only |
| 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. | Read-only |
| stackfacts_kev_snapshot | Download the full signed CISA KEV snapshot: every known exploited vulnerability, with a manifest to verify the sha256 and signature. | Read-only |
| stackfacts_keys | Get the Ed25519 public keys (JWK) that verify the signature on every answer and snapshot manifest. | Read-only |
| stackfacts_manifest | Get the signed manifest of a dataset's latest snapshot for free: snapshot_id, sha256, record count, source, licence and signature. | Read-only |
| stackfacts_models_changes | List LLM models added, removed or changed (price per million tokens, context window, model deprecation date) since a snapshot_id. | Read-only |
| 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. | Read-only |
| 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. | Read-only |
| stackfacts_models_lookup | Get an LLM model's price per million tokens (input, output, cached), context window, max output, capabilities and model deprecation date. | Read-only |
| stackfacts_models_snapshot | Download the full signed LLM model catalogue (LiteLLM + models.dev, MIT): prices, limits and capabilities, with a verifiable manifest. | Read-only |
| stackfacts_osv_check | Check dependencies for known vulnerabilities: up to 50 package purls (npm, PyPI, Go, crates.io, Maven) against OSV.dev, with fixed versions and CISA KEV flags. | Read-only |
| stackfacts_package_card | Get an npm or PyPI package's latest version, publish dates, deprecation or yank, SPDX licence, repository and runtime range. | Read-only |
| 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. | Read-only |
| stackfacts_preview | Preview a dataset for free: sample end-of-life products, the newest CISA KEV entries or LLM prices, signed like the paid answers. | Read-only |
| stackfacts_stack_check | Check dependencies, runtimes and OS versions in one call: OSV advisories for up to 50 package purls, EOL status for 50 product@version pairs, CISA KEV hits. | Read-only |
| 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. | Read-only |
| 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. | Read-only |
| stackfacts_validate | Validate an id for free before paying: whether a product, product/cycle or provider/model exists, or a CVE id is well formed. | Read-only |
