How I Turned a REST API into a Natural Language Interface in Under 5 Minutes (Without SDKs)

If you've ever wished your backend could talk like a human — this one's for you.

I’m building Talkdex, a tool that turns any REST API into a natural language interface you can invoke like you're chatting with a person — or an LLM.

Here’s how I did it, step by step 👇

---

🛠 Step 1: Create your service model

Just give it a name and paste your API schema or JSON example. No OpenAPI, no Swagger, no boilerplate.

---

⚙️ Step 2: Define the destination endpoint

You specify where the request should go — method, URL, token — all done in one screen.

---

💬 Step 3: Talk to your service

Now you can literally type what you want the system to do. For example:

“I want to order wireless noise-cancelling headphones.”

Talkdex turns that input into a structured, working API request.

---

✅ Step 4: See your real response

The service responds in real time, fully structured. And it works exactly as intended.

---

🧠 No SDKs. No glue code. No interface to build.

Just describe your endpoint → run it → and it’s instantly usable by both humans and LLMs.
