AI Tool Setup

Cursor

Use Felo API Platform in Cursor through custom OpenAI-compatible settings where available.

Use this guide when your Cursor setup supports custom OpenAI-compatible endpoints or external provider overrides.

Before You Start

You need one Felo API Platform key. The same key works across model protocols, agent clients, Search, Web Fetch, PPT, Mindmap, LiveDocs, X Search, YouTube Subtitling, Landing Page, and SuperAgent APIs.

export FELO_API_KEY="YOUR_API_KEY"

Recommended Setup

Item	Value
Best for	AI coding inside an editor, repo questions, and code generation
Protocol	OpenAI-compatible Chat Completions
Base URL	`https://openapi.felo.ai/api/v1`
Model example	`claude-sonnet-4-6`
API key	Your `FELO_API_KEY`

Configure Cursor

Set the environment variables first:

export FELO_API_KEY="YOUR_API_KEY"
export OPENAI_API_KEY="$FELO_API_KEY"
export OPENAI_BASE_URL="https://openapi.felo.ai/api/v1"

Client fields

Field	Value
Provider type	OpenAI-compatible custom provider
API key	Your `FELO_API_KEY`
Base URL	`https://openapi.felo.ai/api/v1`
Model	`claude-sonnet-4-6`

If your Cursor version does not expose custom base URL settings, use Claude Code, Codex, OpenCode, or another client that supports custom providers.

Verify the Setup

Run a small task after saving the configuration:

Open Cursor and run a small chat or code edit after saving the provider settings.

If the tool starts and answers with the selected model, the provider setup is ready.

Troubleshooting

Issue	What to check
Authentication fails	Confirm the key is copied correctly and exported as `FELO_API_KEY`
Tool calls the wrong provider	Check that the Felo provider is selected for the current workspace or session
Base URL error	Use `https://openapi.felo.ai/api/v1` for OpenAI-compatible clients and `https://openapi.felo.ai/api` for Anthropic-compatible clients
Model not found	Choose a model that appears in your Felo model list
The tool ignores local config	Move provider settings to the user-level config if the client requires it
