# ClarkCant Marketplace > Discover and curate ClarkCant packages distributed through npm. The marketplace discovers and curates, npm distributes, and the ClarkCant app installs and runs packages after reviewing their permissions. Curation: "listed" means a package passed automated checks (manifest, integrity) when indexed and was not reviewed by a person; "featured" means marketplace curators chose it. Hidden and rejected packages are not published anywhere. A "verified" publisher proved control of a web domain with a DNS TXT record; it says nothing about code quality. npm provenance is recorded when present, not verified by the marketplace. Every indexable catalogue and content page has a Markdown twin at the same path plus `.md` (the home page: `/index.md`); the API reference's machine-readable form is `/openapi.json`. ## Start here - [Home](https://marketplace.clarkcant.cc/index.md): What the marketplace lists and how installing works - [All packages](https://marketplace.clarkcant.cc/packages.md): The package listing, with categories and the search API - [Collections](https://marketplace.clarkcant.cc/collections.md): Curated sets of packages - [HTTP API (OpenAPI 3.1)](https://marketplace.clarkcant.cc/openapi.json): Search, package details, install coordinates - [About the ClarkCant Marketplace](https://marketplace.clarkcant.cc/about.md): How the ClarkCant Marketplace lists, describes and curates packages distributed through npm. - [Publish a package to the ClarkCant Marketplace](https://marketplace.clarkcant.cc/publish.md): How to list a ClarkCant widget, tool or theme: publish it to npm with a clarkcant.json manifest and a ClarkCant keyword, then let the marketplace index it. ## Policies - [Cookie Policy](https://marketplace.clarkcant.cc/cookies.md): Draft cookie policy: the cookies and browser storage the ClarkCant Marketplace uses, by category, and how to change your choice. - [Your GDPR rights](https://marketplace.clarkcant.cc/gdpr.md): Draft GDPR notice: your data protection rights for the ClarkCant Marketplace and the self-service tools to exercise them. - [Privacy Policy](https://marketplace.clarkcant.cc/privacy.md): Draft privacy policy: which personal data the ClarkCant Marketplace stores, why, for how long, and how to export or delete it. - [Refund Policy](https://marketplace.clarkcant.cc/refunds.md): The ClarkCant Marketplace has no paid transactions, so there is nothing to refund. - [Security](https://marketplace.clarkcant.cc/security.md): How the ClarkCant Marketplace handles package trust: the security boundary, what verified, listed and featured mean, and how to report a vulnerability. - [Subprocessors](https://marketplace.clarkcant.cc/subprocessors.md): Draft list of the third parties that process data for the ClarkCant Marketplace, and the external services it depends on. - [Terms of Service](https://marketplace.clarkcant.cc/terms.md): Draft terms for using the ClarkCant Marketplace: what the service does, what it does not do, and your responsibilities. ## Optional - [Full text of the site's own pages](https://marketplace.clarkcant.cc/llms-full.txt) - [Sitemap](https://marketplace.clarkcant.cc/sitemap.xml): Every public package and page
