Next Level Builders API

Explore request schemas, generate code snippets and send real requests with the interactive reference below.

Create an API key in your profile. Builder endpoints accept Authorization: Bearer nlb_live_… or x-api-key: nlb_live_…. Organization membership is required. Voting and key management require a signed-in browser session.

Use the current website origin for session requests. Requests sent with “Test Request” run against the server you select and can save drafts or submit for review. Credentials are not persisted by this reference.

HTTP MCP: https://mcp.nextlevelbuilder.io/mcp. To design a draft in your browser, enable WebMCP in Studio and connect your client.
