Authentication

All API requests require an API key. You can get your API key by signing up at Token Metrics.

// Initialize with your API key
const client = new TokenMetricsClient('your-api-key');

Error Handling

The SDK provides built-in error handling for API requests:

client.tokens.get({ symbol: 'INVALID_SYMBOL' })
  .then(data => {
    console.log(data);
  })
  .catch(error => {
    console.error('Error:', error.message);
    // Handle the error appropriately
  });

// Using async/await with try/catch
async function getTokenData(): Promise<void> {
  try {
    const data = await client.tokens.get({ symbol: 'INVALID_SYMBOL' });
    console.log(data);
  } catch (error: unknown) {
    if (error instanceof Error) {
      console.error('Error:', error.message);
    } else {
      console.error('Unknown error:', error);
    }
    // Handle the error appropriately
  }
}

Requirements

• Node.js 14+
• axios package
• express package

Express.js Integration

This SDK can be easily integrated with Express.js to create your own API endpoints that leverage Token Metrics data:

import express from 'express';
import cors from 'cors';
import { TokenMetricsClient } from 'tmai-api';

// Initialize the Token Metrics client
const tmClient = new TokenMetricsClient('your-api-key');

// Create Express app
const app = express();
const port = 3000;

// Middleware
app.use(cors());
app.use(express.json());

// Get tokens endpoint
app.get('/api/tokens/:symbol', async (req, res) => {
  try {
    const { symbol } = req.params;
    const result = await tmClient.tokens.get({ symbol });
    res.json(result);
  } catch (error) {
    if (error instanceof Error) {
      res.status(500).json({ error: error.message });
    } else {
      res.status(500).json({ error: 'Unknown error occurred' });
    }
  }
});

// Get trading signals endpoint
app.get('/api/trading-signals/:symbol', async (req, res) => {
  try {
    const { symbol } = req.params;
    const { start_date, end_date, signal } = req.query;
    
    const result = await tmClient.tradingSignals.get({
      symbol,
      start_date: start_date as string | undefined,
      end_date: end_date as string | undefined,
      signal: signal as string | undefined
    });
    
    res.json(result);
  } catch (error) {
    if (error instanceof Error) {
      res.status(500).json({ error: error.message });
    } else {
      res.status(500).json({ error: 'Unknown error occurred' });
    }
  }
});

// Start the server
app.listen(port, () => {
  console.log(`Server running at http://localhost:${port}`);
});
