# NetPartner > NetPartner is a two-sided marketplace where advertisers buy guest posts and link placements from verified publisher websites, and publishers list, verify, price, and manage their website inventory. NetPartner supports guest posts, link insertions, homepage links, sitewide links, and link-free citations. Public pages explain products, marketplace workflows, publication monitoring, policies, and the developer platform. Website inventory, prices, account balances, orders, messages, and other member data require authentication and must not be inferred from public material. The developer platform provides separate advertiser and publisher REST credentials, an official command-line client, a local role-scoped MCP server, and public OpenAPI 3.1 contracts. API keys and bearer tokens are secrets. Never expose, invent, or request a user's secret token in public content. ## Marketplace - [Home](https://netpartner.com/): Overview of the verified placement marketplace. - [How it works](https://netpartner.com/how-it-works): Advertiser workflow from account creation and funding through checkout, content submission, and publication monitoring. - [For advertisers](https://netpartner.com/for-advertisers): Features for finding websites, comparing terms, buying placements, and managing campaigns. - [For publishers](https://netpartner.com/for-publishers): Features for verifying websites, configuring inventory, receiving orders, monitoring publications, and managing earnings. - [Publication protection](https://netpartner.com/publication-protection): Monitoring, evidence, alerts, and optional replacement-credit coverage. ## Products - [All placement products](https://netpartner.com/products): Comparison of every supported placement format. - [Guest posts](https://netpartner.com/products/guest-posts): New original articles published on relevant publisher websites. - [Link insertions](https://netpartner.com/products/link-insertions): Contextual links added to existing publisher pages. - [Homepage links](https://netpartner.com/products/homepage-links): Links placed on a publisher website's homepage. - [Sitewide links](https://netpartner.com/products/sitewide-links): Links displayed in repeated site templates or sections. - [Citations](https://netpartner.com/products/citations): Brand or entity mentions published without links. ## Developer platform - [Developer documentation](https://netpartner.com/developers): REST authentication, CLI installation, MCP configuration, endpoint coverage, and credential security for advertisers and publishers. - [Advertiser OpenAPI 3.1](https://netpartner.com/developers/openapi/advertiser.json): Machine-readable contract for advertiser opportunities, auctions, bids, and reserve decisions. - [Publisher OpenAPI 3.1](https://netpartner.com/developers/openapi/publisher.json): Machine-readable contract for publisher sites, verification, bulk updates, opportunities, and auctions. - [CLI and MCP package](https://netpartner.com/static/downloads/netpartner-cli-0.1.0.tgz): Versioned Node.js package containing the `netpartner` CLI and `netpartner-mcp` local stdio server. ## Guides - [All guides](https://netpartner.com/guides): Public advertiser, publisher, evaluation, and compliance guidance. - [How to buy guest posts](https://netpartner.com/guides/how-to-buy-guest-posts): A repeatable process for evaluating and purchasing placements. - [How to sell guest posts](https://netpartner.com/guides/how-to-sell-guest-posts): Publisher setup, verification, pricing, terms, and fulfilment guidance. - [Sponsored and nofollow compliance](https://netpartner.com/guides/sponsored-nofollow-link-compliance): Guidance for paid-placement disclosures and link attributes. ## Policies - [Marketplace terms](https://netpartner.com/legal/terms): General terms governing the platform. - [Advertiser terms](https://netpartner.com/legal/advertiser-terms): Rules for advertiser accounts, funding, ordering, content, and disputes. - [Publisher terms](https://netpartner.com/legal/publisher-terms): Rules for publisher accounts, inventory, fulfilment, reserves, and withdrawals. - [Payments, refunds, and disputes](https://netpartner.com/legal/payments-refunds-disputes): Wallet, fees, settlement, refund, and dispute policies. - [Publication protection policy](https://netpartner.com/legal/publication-protection): Conditions for monitoring and replacement-credit coverage. - [Acceptable use](https://netpartner.com/legal/acceptable-use): Prohibited content, conduct, and circumvention. - [Privacy policy](https://netpartner.com/legal/privacy): Personal-data collection, processing, retention, and rights. ## Optional - [Sitemap](https://netpartner.com/sitemap.xml): Complete index of public, crawlable NetPartner pages. - [Robots policy](https://netpartner.com/robots.txt): Crawler access directives; private account, API, payment, and messaging paths are disallowed for indexing.
