#gmgn #defi #crypto #token

The cryptocurrency market moves fast, and staying ahead of trends can make all the difference. Whether you're building a trading bot, portfolio tracker, or market analysis tool, having access to real-time token data is crucial. Today, I'll walk you through the GMGN.AI API - a powerful tool for tracking trending tokens across multiple blockchains.

What is GMGN.AI API?

GMGN.AI provides a comprehensive API that allows developers to access trending token data across major blockchains including Ethereum, Solana, Base, BSC, and Tron. What sets it apart is its focus on smart money tracking and safety filters to help identify legitimate opportunities while avoiding honeypots and scams.

Important Implementation Considerations

⚠️ Network Protection Notice: The GMGN.AI API is protected by advanced security measures including Cloudflare protection. For production applications, you'll need to implement appropriate request handling solutions that can work with protected endpoints. Consider using proxy services, rotating user agents, or specialized HTTP clients that can handle modern web security measures.

Key Features

🔍 Multi-chain Support: Ethereum, Solana, Base, BSC, and Tron

📊 Multiple Sorting Criteria: Volume, market cap, holder count, smart money activity, and more

🛡️ Safety Filters: Built-in honeypot detection, verification status, and ownership renouncement

⏱️ Flexible Time Periods: From 1-minute to 24-hour trending data

💡 Smart Money Insights: Track what experienced traders are buying and selling

Getting Started

The GMGN.AI API uses a RESTful endpoint structure that's easy to understand and implement:

https://gmgn.ai/defi/quotation/v1/rank/{chain}/swaps/{time_period}?orderby={criteria}&direction={direction}&filters[]={safety_filters}

Basic Parameters

Supported Chains {chain}:

eth - Ethereum
sol - Solana
base - Base
bsc - Binance Smart Chain
tron - Tron

Time Periods {time_period}:

1m, 5m, 1h, 6h, 24h

Sorting Criteria {criteria}:

volume - 24h trading volume
marketcap - Market capitalization
swaps - Number of transactions
holder_count - Number of holders

Practical Examples

Let's dive into some real-world use cases with code examples.

Level 1: Basic Token Discovery

High-Volume Ethereum Token Scanner

async function getHighVolumeTokens() {
    const url = 'https://gmgn.ai/defi/quotation/v1/rank/eth/swaps/6h?orderby=volume&direction=desc&filters[]=not_honeypot&filters[]=verified&filters[]=renounced';

    // Note: For production use, implement appropriate request handling
    // that can work with protected endpoints
    const requestOptions = {
        method: 'GET',
        headers: {
            'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36',
            'Accept': 'application/json',
            'Referer': 'https://gmgn.ai/',
        }
    };

    try {
        const response = await fetch(url, requestOptions);
        const data = await response.json();

        if (data.code === 0) {
            const topTokens = data.data.rank.slice(0, 10);

            topTokens.forEach((token, index) => {
                console.log(`${index + 1}. ${token.symbol}`);
                console.log(`   Volume: ${token.volume.toLocaleString()}`);
                console.log(`   Price: ${token.price}`);
                console.log(`   Market Cap: ${token.market_cap.toLocaleString()}`);
                console.log(`   Holders: ${token.holder_count}`);
                console.log('---');
            });
        }
    } catch (error) {
        console.error('Error:', error);
        // Consider implementing retry logic with exponential backoff
    }

Level 3: Enterprise-Grade API Client

Production-Ready GMGN Client

class GMGNApiClient {
    constructor() {
        this.baseUrl = 'https://gmgn.ai/defi/quotation/v1/rank';
        this.defaultHeaders = {
            'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36',
            'Accept': 'application/json',

        };
        this.requestQueue = [];
        this.isProcessing = false;
    }

    async makeRequest(url, options = {}) {
        return new Promise((resolve, reject) => {
            this.requestQueue.push({ url, options, resolve, reject });
            this.processQueue();
        });
    }

    async processQueue() {
        if (this.isProcessing || this.requestQueue.length === 0) return;

        this.isProcessing = true;

        while (this.requestQueue.length > 0) {
            const { url, options, resolve, reject } = this.requestQueue.shift();

            try {
                // Add delay between requests to avoid rate limiting
                await this.delay(1000);

                    ...options,
                    headers: { ...this.defaultHeaders, ...options.headers }
                });

                    });

                    if (retryResponse.ok) {
                        const data = await retryResponse.json();

                } catch (retryError) {
                    reject(retryError);
                }
            }
        }

        this.isProcessing = false;
    }

    delay(ms) {
        return new Promise(resolve => setTimeout(resolve, ms));
    }

    async getTrendingTokens(chain, timePeriod, orderBy = 'volume', filters = ['not_honeypot']) {
        const params = new URLSearchParams({
            orderby: orderBy,
            direction: 'desc'
        });

        filters.forEach(filter => params.append('filters[]', filter));

        const url = `${this.baseUrl}/${chain}/swaps/${timePeriod}?${params}`;

        return this.makeRequest(url);
    }
}

// Usage example
const apiClient = new GMGNApiClient();

async function findNewGems(chain = 'base') {
    try {
        const data = await apiClient.getTrendingTokens(
            chain, 
            '1h', 
            'open_timestamp', 
            ['not_honeypot', 'verified', 'renounced']
        );

        if (data.code === 0) {
            const currentTime = Math.floor(Date.now() / 1000);

            const newTokens = data.data.rank.filter(token => {
                const tokenAge = currentTime - token.open_timestamp;
                return tokenAge <= 3600 && // Less than 1 hour old
                       token.holder_count > 50 && 
                       token.volume > 10000;
            });

            console.log('💎 New Gems Found:', newTokens.length);
            return newTokens;
        }
    } catch (error) {
        console.error('Failed to fetch new gems:', error);
        return [];
    }
}

Best Practices for Production Use

1. Implement Robust Error Handling

class APIErrorHandler {
    static async handleRequest(requestFn, maxRetries = 3) {
        for (let attempt = 1; attempt <= maxRetries; attempt++) {
            try {
                return await requestFn();
            } catch (error) {
                console.log(`Attempt ${attempt} failed:`, error.message);

                if (attempt === maxRetries) {
                    throw new Error(`All ${maxRetries} attempts failed: ${error.message}`);
                }

                // Exponential backoff with jitter
                const delay = Math.min(1000 * Math.pow(2, attempt) + Math.random() * 1000, 30000);
                await new Promise(resolve => setTimeout(resolve, delay));
            }
        }
    }
}

2. Request Rate Limiting

class RateLimiter {
    constructor(requestsPerMinute = 30) {
        this.requests = [];
        this.limit = requestsPerMinute;
    }

    async waitIfNeeded() {
        const now = Date.now();
        this.requests = this.requests.filter(time => now - time < 60000);

        if (this.requests.length >= this.limit) {
            const oldestRequest = Math.min(...this.requests);
            const waitTime = 60000 - (now - oldestRequest) + 1000; // Add 1s buffer
            console.log(`Rate limit reached, waiting ${waitTime}ms`);
            await new Promise(resolve => setTimeout(resolve, waitTime));
        }

        this.requests.push(now);
    }
}

3. Data Caching Strategy

class CacheManager {
    constructor(ttl = 60000) { // 1 minute default TTL
        this.cache = new Map();
        this.ttl = ttl;
    }

    set(key, value) {
        this.cache.set(key, {
            value,
            timestamp: Date.now()
        });
    }

    get(key) {
        const item = this.cache.get(key);

        if (!item) return null;

        if (Date.now() - item.timestamp > this.ttl) {
            this.cache.delete(key);
            return null;
        }

        return item.value;
    }

    clear() {
        this.cache.clear();
    }
}
