Value Betting Bot

This example builds a Discord/Telegram bot that alerts you to +EV opportunities in real-time.

Architecture


SharpAPI SSE Stream → Bot Server → Discord/Telegram

Implementation

1. Set Up Dependencies


npm install eventsource discord.js dotenv

2. Create the Bot


// ev-bot.js
import EventSource from 'eventsource';
import { Client, GatewayIntentBits, EmbedBuilder } from 'discord.js';
 
const SHARP_API_KEY = process.env.SHARP_API_KEY;
const DISCORD_TOKEN = process.env.DISCORD_TOKEN;
const CHANNEL_ID = process.env.DISCORD_CHANNEL_ID;
 
// Discord setup
const discord = new Client({ intents: [GatewayIntentBits.Guilds] });
 
discord.once('ready', () => {
  console.log('Discord bot ready');
  startEVStream();
});
 
// EV Stream
function startEVStream() {
  const url = `https://api.sharpapi.io/api/v1/stream?channel=opportunities&min_ev=3.0&api_key=${SHARP_API_KEY}`;
  const es = new EventSource(url);
 
  es.addEventListener('ev:detected', async (e) => {
    const { opportunities } = JSON.parse(e.data).data;
 
    for (const opp of opportunities) {
      await sendAlert(opp);
    }
  });
 
  es.onerror = (err) => {
    console.error('Stream error:', err);
  };
}
 
// Send Discord alert
async function sendAlert(opp) {
  const channel = await discord.channels.fetch(CHANNEL_ID);
 
  const embed = new EmbedBuilder()
    .setColor(opp.ev_percent >= 5 ? 0xFF0000 : 0x00FF00)
    .setTitle(`${opp.ev_percent >= 5 ? '🔥' : '✅'} +EV Alert`)
    .setDescription(`**${opp.game}**`)
    .addFields(
      { name: 'Selection', value: opp.selection, inline: true },
      { name: 'Book', value: opp.sportsbook, inline: true },
      { name: 'Odds', value: String(opp.odds_american), inline: true },
      { name: 'EV', value: `+${opp.ev_percent}%`, inline: true },
      { name: 'Kelly', value: `${opp.kelly_fraction}`, inline: true },
      { name: 'Devig', value: `${opp.no_vig_odds} (${opp.devig_book})`, inline: true },
    )
    .setTimestamp();
 
  await channel.send({ embeds: [embed] });
}
 
discord.login(DISCORD_TOKEN);

3. Run It


SHARP_API_KEY=sk_live_xxx \
DISCORD_TOKEN=xxx \
DISCORD_CHANNEL_ID=xxx \
node ev-bot.js

Filtering

Customize which alerts you receive:


es.addEventListener('ev:detected', async (e) => {
  const { opportunities } = JSON.parse(e.data).data;
 
  for (const opp of opportunities) {
    // Only high EV
    if (opp.ev_percent < 5) continue;
 
    // Only certain sports
    if (!['nba', 'nfl'].includes(opp.sport)) continue;
 
    // Only certain books
    if (!['draftkings', 'fanduel'].includes(opp.sportsbook)) continue;
 
    await sendAlert(opp);
  }
});

Telegram Version


import TelegramBot from 'node-telegram-bot-api';
 
const bot = new TelegramBot(process.env.TELEGRAM_TOKEN, { polling: false });
const chatId = process.env.TELEGRAM_CHAT_ID;
 
async function sendTelegramAlert(opp) {
  const message = `
${opp.ev_percent >= 5 ? '🔥' : '✅'} *+EV Alert*
 
*${opp.game}*
Selection: ${opp.selection}
Book: ${opp.sportsbook}
Odds: ${opp.odds_american}
EV: +${opp.ev_percent}%
Kelly: ${opp.kelly_fraction}
  `.trim();
 
  await bot.sendMessage(chatId, message, { parse_mode: 'Markdown' });
}
