# saascode — public API > Public read-only catalog lookup needs no account or API key. Use the OpenAPI document for exact parameters, operation IDs and response schemas. Purchase and member-only access keep their existing rules. ## Documentation - [Developer guide](https://saascode.ai/developers.md): catalog lookup, errors and Markdown negotiation - [OpenAPI 3.1 specification](https://saascode.ai/openapi.json): typed catalog operations, parameters and responses - [Homepage in Markdown](https://saascode.ai/index.md): what SaaSCode does and who it is for - [Growth overview](https://saascode.ai/growth.md): marketing workspace for catalog product owners; its operational actions require the owner's signed-in dashboard ## Public catalog - [Catalog list](https://saascode.ai/api/catalog): paginated public products; supports search, category and other documented filters - [Catalog index](https://saascode.ai/products/llms.txt): resolve a product slug and read its Markdown description - [Inside index](https://saascode.ai/inside/llms.txt): published articles and product records Read one product with GET /api/catalog/{slug}. Status and availability in the response govern what is available; a visible beta or coming-soon listing is not a promise that checkout is open. ## Membership and purchase - [Plus](https://saascode.ai/plus): membership and Genesis MCP access; distinct from the unauthenticated public catalog API - [Terms](https://saascode.ai/terms): product licences and permitted use - [Support](https://saascode.ai/support): help with an account or purchase ## Navigation - [Site index](https://saascode.ai/llms.txt): offer and public documentation
