ChatGPT
There are two ways to connect: (1) the Custom Connector (MCP) feature on Pro/Enterprise, or (2) a Custom GPT Action in GPT Builder that calls the REST API directly.
Prerequisites
A ChatGPT Pro/Team/Enterprise plan, or a Plus-or-higher account that can build Custom GPTs. The Action approach requires a FindIP API key.
Setup steps
Option 1 — Custom Connector (Pro/Enterprise, recommended)
ChatGPT bottom-left profile → Settings → Connectors → Add custom connector → register the URL below → sign in to FindIP from the OAuth popup.
https://api.findip.ai/mcp
Option 2 — Custom GPT Action (Plus or higher)
In GPT Builder, create a new GPT → Configure → Actions → Create new action → Authentication: API Key, Custom Header Name = X-API-Key → paste the OpenAPI schema below.

Sample prompt
Prompt
"Compare LG Energy Solution and Samsung SDI's major Korean and US filings over the past 5 years on single-crystal synthesis processes for cathode materials in secondary batteries."
Troubleshooting
The Custom Connector menu is missing.
Plan-permissions issue. Upgrade to Pro or higher, or use the GPT Builder Action approach instead.
The Action returns 401 Unauthorized.
Confirm the API-key header is exactly X-API-Key, and verify the key is active in the dashboard.
