Welcome to the BaseCMS Developer program! ### About the API The BaseCMS API can be accessed using GraphQL -- an abstract query language for retrieving data in a standard format, originally developed by the team at Facebook. [GraphQL Playground](https://github.com/prisma-labs/graphql-playground) can be used as a locally installed API client, or the GraphQL connection can be accessed programmatically in most languages with the use of [a client](https://graphql.org/code/#graphql-clients). For more information about using GraphQL, check out the [docs](https://graphql.org/learn/). {% hint style="info" %} You'll need the following information to read data from the API: * An API URL * A Tenant Key * An active Base user with permission to read data If you're missing any of this, please reach out to and we'd be happy to help you out! {% endhint %} ### Connecting to the API Your GraphQL production and staging URLs will be provided, and should look something like this: `.graphql.base.parameter1.com` or `.graphql.base-staging.parameter1.com`. The API must be accessed via HTTP/S on port `443`. Requests to the GraphQL API must include the `x-tenant-key` header for the Base instance in question: such as `x-tenant-key: my-base-instance-id`. Once connected, you can see available query documentation and schema definitions within the GraphQL Playground application. For more in-depth information, see the topics on [Querying Data](/basecms-graphql/querying-data/introduction.md) and [Modifying Data](/basecms-graphql/modifying-data/introduction.md). --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.parameter1.com/basecms-graphql/master.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
