Quickstart

import { Verlon } from '@verlon-ai/sdk';

const verlon = new Verlon({ apiKey: process.env.VERLON_API_KEY });

const response = await verlon.chat({
  gateId: process.env.GATE_ID,
  model: 'gemini-2.5-pro', // optional — overrides the gate's configured model
  data: {
    messages: [{ role: 'user', content: 'Hello!' }],
  },
});

console.log(response.content);

SDK compatibility

​

Streaming

for await (const chunk of verlon.chatStream({
  gateId: process.env.GATE_ID,
  data: { messages: [{ role: 'user', content: 'Tell me a joke.' }] },
})) {
  process.stdout.write(chunk.content ?? '');
}

What’s supported

​

How it works

1. You send a request in your chosen SDK’s format
2. Verlon receives — validates the gate, applies routing rules
3. Verlon translates to Gemini’s native format and dispatches to Google’s API
4. Google responds with the raw Gemini response
5. Verlon normalizes back to your SDK’s expected shape (OpenAI, Anthropic, or Verlon-native)
6. You receive a response in the format your code already handles, with an added cost field

​

Errors

try {
  await verlon.chat({
    gateId: process.env.GATE_ID,
    data: { messages: [{ role: 'user', content: 'Hello!' }] },
  });
} catch (error) {
  // error.message carries the API's message,
  // e.g. 'Gate with ID "…" not found'
  console.error(error.message);
}
