Quickstart: ChatGPT

The simplest way to use Pipeworx in ChatGPT is a Custom GPT with an Action — no Developer mode required. It calls Pipeworx’s REST endpoint, which routes your question across 5,929 tools and 1,544 sources and returns cited, structured data. (Prefer the full MCP connector instead? See the bottom of this page.)

① Connect

  1. ChatGPT → Explore GPTs → + Create → Configure tab. Name it Pipeworx.
  2. Actions → Create new action.
  3. Authentication: None.
  4. Schema → Import from URL and paste: 
    https://gateway.pipeworx.io/openapi.json
    ChatGPT imports two operations — askPipeworx (POST) and askPipeworxGet (GET) — both pointing at gateway.pipeworx.io/ask. Either works; the GPT picks one.
  5. Privacy policy: https://pipeworx.io/privacy
  6. Create (Only me is fine for testing; sharing publicly requires the privacy URL above).

Custom GPTs also work in the ChatGPT mobile app — open it from your GPTs list.

② Teach it to use Pipeworx

In the GPT’s Instructions box, paste this so it calls the Action instead of answering from memory or browsing:

For any question about current or factual data — economic stats, SEC/EDGAR filings, stock or crypto prices, weather, FDA drug info, patents, prediction markets, or government records — call the askPipeworx action with the user's question verbatim instead of answering from memory or browsing. Cite the structured data it returns.

③ Test

Open your Pipeworx GPT and ask:

“Apple’s latest 10-K revenue”

It should call askPipeworx and answer with SEC data. If it answers from memory, tighten the Instructions in step ②.

Higher limits

The Action runs on the anonymous tier (50 requests/day per IP). For 200/day, sign up free at pipeworx.io/signup, grab a key at pipeworx.io/account, and append it to the server URL in the Action schema (https://gateway.pipeworx.io/ask?apikey=YOUR_KEY). Tiers: anonymous 50/day · free account 200/day · Paid unlimited.

Full MCP connector (optional, Developer mode)

If you want all tools inside the main ChatGPT chat (not a Custom GPT), use the MCP connector instead. Turn on Developer mode in ChatGPT settings, then add a developer-mode app for the URL https://gateway.pipeworx.io/pipeworx-catalog/mcp with Authentication None. Then paste the routing rule into Settings → Personalization → Custom instructions.

OpenAI renamed this surface from Connectors to Apps and has moved the toggle more than once, so follow OpenAI’s own developer-mode guide for the current path rather than a screenshot. What matters here: it is available on Plus, Pro, Business, Enterprise and Education (Free is excluded) — it is no longer Pro/Business/Enterprise only.

Troubleshooting

Schema import rejected. The OpenAPI URL must be reachable and valid — paste https://gateway.pipeworx.io/openapi.json exactly.

Action never fires. Strengthen the Instructions in step ② so the GPT always calls askPipeworx for factual questions.

Privacy policy required. ChatGPT asks for one when you add an Action — use https://pipeworx.io/privacy.
