# Use DataXAPI in ChatGPT Yes: add one MCP address to ChatGPT and it reads public Xiaohongshu, Douyin, WeChat and TikTok data itself, in three steps. Sign in to DataXAPI and approve; no key to copy: 5 tools, 224 endpoints on 21 platforms, from $0.0003 a call, and a failed call is never charged. The address ChatGPT connects to: `https://api.dataxapi.com/mcp`. One address. You sign in to DataXAPI and approve; no key is copied anywhere. ## Connect it Three steps inside ChatGPT: the address, then sign in to DataXAPI and approve. No key is typed anywhere. Written from the client's own documentation. 1. Open the place MCP servers are added: ChatGPT on the web: Plugins → + → Add custom MCP server; the name, the MCP address and OAuth as its authentication; tick the risk notice and choose Create as a plugin 2. Fill in the fields: One address. You sign in to DataXAPI and approve; no key is copied anywhere. | Field | Value | | --- | --- | | Name | DataXAPI | | URL | https://api.dataxapi.com/mcp | | Authentication | OAuth: sign in to DataXAPI and approve | 3. Save, then ask it to list the tools: You should get the five below. ## Check it works Ask it to list the tools. This is the reply to expect; none of it costs anything. > List the DataXAPI tools. DataXAPI is connected with 5 tools: `find` finds the endpoint for a question, `describe` shows its parameters and price, `call` runs it (the only one that is charged), `read_more` re-reads a result for 24 hours, and `account` shows your balance. The catalog has 224 endpoints on 21 platforms. ## A first conversation A question, the calls it made, and what each one cost. > What has @nasa posted on TikTok lately? | | | | | --- | --- | --- | | `find({ query: "tiktok account recent videos" })` | Found tiktok.users.videos.list · TikTok user videos · $0.0020 a call | Free | | `call({ capability: "tiktok.users.videos.list", username: "nasa", max_price: "0.01" })` | Up to 10 videos · compact view | $0.0020 | 2 tool calls · 1 charged · $0.0020 ## Tips for ChatGPT - **Give it its own key.** Create a key named “ChatGPT” with a daily budget in the console. When the budget is used up, calls stop; nothing else on your account is touched. - **Let the free tools run without asking.** If ChatGPT asks before it runs a tool, allow `find`, `describe`, `read_more` and `account`. Leave `call` on “ask” if you want to approve every charge. - **Answers fit the context.** A DataXAPI answer stops at about 20 KB on an item boundary and says how to read on; `read_more` gets the rest at no charge. - **Cap what a call may cost.** Ask it to pass `max_price` with every call. A call that could cost more is refused before anything is charged. ## What to know about ChatGPT - ChatGPT's help centre gives custom MCP servers to ChatGPT Business and Enterprise/Edu, on the web only; on Business only admins and owners add one. On Pro only read and fetch tools can be used, so `call`, which is not marked read-only, may not run there. - ChatGPT cannot send an API key: it connects by OAuth only. You sign in to DataXAPI and approve once; calls are charged to that account's balance. - In a workspace, the tools are frozen when an admin approves the server; an admin chooses Refresh when they change. ### The first call Open a new chat, type @ and pick DataXAPI, then ask: “@DataXAPI What are the top Xiaohongshu notes on camping this week?” Allow the call when ChatGPT asks.

The two free tools need no key, so they still answer. | Check that the key is where the entry reads it from, and that it starts with `dx_`. Then restart. | | `call` says `insufficient_balance` or `key_budget_exceeded` | The balance, or this key's budget, does not cover the price of the call. Nothing was charged. | Ask it to run `account`, then top up or raise the key's budget. | ## All clients - [Use DataXAPI in Claude Code](https://dataxapi.com/integrations/claude-code/) - [Use DataXAPI in Cursor](https://dataxapi.com/integrations/cursor/) - [Use DataXAPI in Codex](https://dataxapi.com/integrations/codex/) - [Use DataXAPI in n8n](https://dataxapi.com/integrations/n8n/) - [Use DataXAPI in Cherry Studio](https://dataxapi.com/integrations/cherry-studio/) - [Use DataXAPI in Trae](https://dataxapi.com/integrations/trae/) - [Use DataXAPI in 扣子 Coze](https://dataxapi.com/integrations/coze/) - [Use DataXAPI in Dify](https://dataxapi.com/integrations/dify/) - [Use DataXAPI in Claude](https://dataxapi.com/integrations/claude/) - [Use DataXAPI in Feishu (Lark)](https://dataxapi.com/integrations/feishu/) - [MCP](https://dataxapi.com/mcp/) - [What an agent reads to set itself up](https://dataxapi.com/agents/) --- Generated from catalog revision 5c3194deef3264cc, price book 6.
