Authentication

Send the key in the header.

Trim accidental whitespace and keep the key private. Do not paste it into public code or screenshots.

Authorization: Bearer <your-issued-np-key>

OpenAI-compatible client

Use the SDK you already know.

const OpenAI = require("openai");

const client = new OpenAI({
  apiKey: process.env.NAG_API_KEY,
  baseURL: "https://api.diwakaryadav.com.np/v1"
});

const response = await client.chat.completions.create({
  model: process.env.NAG_MODEL,
  messages: [{ role: "user", content: "Namaste" }]
});

console.log(response.choices[0].message.content);

import os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["NAG_API_KEY"],
    base_url="https://api.diwakaryadav.com.np/v1",
)

response = client.chat.completions.create(
    model=os.environ["NAG_MODEL"],
    messages=[{"role": "user", "content": "Namaste"}],
)

print(response.choices[0].message.content)

Model access

Choose from your live model catalog.

The model list endpoint is the single source of truth — it only ever shows models that are available to your key right now. Call it, pick a slug from the response, and start.

Free plan: free keys call diwakar — the stealth-routed model included at no cost. Pro plan: unlocks the broader catalog as providers are verified and wired; the same endpoint shows them the moment they come online. Premium flagship models spend quota faster per token than standard ones when available — the response's _meta and your account page keep you informed.

# Public: returns the free-tier catalog, no key required and no quota used
curl https://api.diwakaryadav.com.np/v1/models

# With a key: returns your plan-filtered catalog (still quota-free)
curl https://api.diwakaryadav.com.np/v1/models \
  -H "Authorization: Bearer <your-issued-np-key>"

Rate limits and quota

Two limits can stop a request.

Free trial

Try the gateway with one key, no credit card.

Sign up at trial.html with Google. You get one gateway key, shown once at first issue, that works against the same /v1 endpoint as paid keys but is routed exclusively to verified-free models.

• 1 key per identity — the full secret appears only at signup; sign in daily with Google to keep the key active.
• 5,000,000 tokens daily, 10 requests/minute, 200K context window.
• Expires at midnight UTC — sign in within the trial window to re-enable the same key.
• No paid-provider fallback. Free requests never silently hit a paid upstream.

Trial requests are logged for operations, abuse prevention, analytics, and quality improvement. Prompt bodies are stored only in hashed form. When you upgrade, the same key keeps working.

diwakar — a private, stealth-routed multimodal model, available for a limited time. The upstream does not train on your data.
