# CoinGecko Solana API Development Guide

A comprehensive guide for integrating CoinGecko's on-chain API for Solana. Access real-time token prices, DEX pool data, OHLCV charts, trade history, and market analytics across 1,700+ decentralized exchanges.

## Overview

CoinGecko's Solana API provides:
- **Token Prices**: Real-time prices by contract address (single or batch)
- **Pool Data**: Liquidity pool information, trending pools, top pools
- **OHLCV Charts**: Candlestick data for technical analysis
- **Trade History**: Recent trades for any pool
- **DEX Discovery**: List all DEXes operating on Solana
- **Search**: Find pools by token name, symbol, or address
- **Megafilter**: Advanced filtering across pools, tokens, and DEXes

### Key Features

| Feature | Description |
|---------|-------------|
| **250+ Networks** | Multi-chain support including Solana |
| **1,700+ DEXes** | Raydium, Orca, Jupiter, Meteora, Pump.fun, etc. |
| **15M+ Tokens** | Comprehensive token coverage |
| **Real-time Data** | Updates every 10-30 seconds |
| **Historical Data** | OHLCV charts and trade history |

## Quick Start

### Get Your API Key

1. **Demo API (Free)**: Visit [coingecko.com/en/api](https://www.coingecko.com/en/api)
2. **Pro API (Paid)**: Visit [coingecko.com/en/api/pricing](https://www.coingecko.com/en/api/pricing)

### Environment Setup

```bash
# .env file
COINGECKO_API_KEY=your_api_key_here
COINGECKO_API_TYPE=demo  # or 'pro'
```

### API Configuration

```typescript
// Configuration for both Demo and Pro APIs
const CONFIG = {
  demo: {
    baseUrl: 'https://api.coingecko.com/api/v3/onchain',
    headerKey: 'x-cg-demo-api-key',
    rateLimit: 30, // calls per minute
  },
  pro: {
    baseUrl: 'https://pro-api.coingecko.com/api/v3/onchain',
    headerKey: 'x-cg-pro-api-key',
    rateLimit: 500, // calls per minute (varies by plan)
  },
};

const apiType = process.env.COINGECKO_API_TYPE || 'demo';
const apiKey = process.env.COINGECKO_API_KEY;

const BASE_URL = CONFIG[apiType].baseUrl;
const HEADER_KEY = CONFIG[apiType].headerKey;

// Solana network identifier
const NETWORK = 'solana';
```

### Basic Token Price Fetch

```typescript
async function getTokenPrice(tokenAddress: string): Promise<number | null> {
  const url = `${BASE_URL}/simple/networks/${NETWORK}/token_price/${tokenAddress}`;

  const response = await fetch(url, {
    headers: {
      [HEADER_KEY]: apiKey,
      'Accept': 'application/json',
    },
  });

  if (!response.ok) {
    throw new Error(`API error: ${response.status}`);
  }

  const data = await response.json();
  return data.data?.attributes?.token_prices?.[tokenAddress] ?? null;
}

// Usage
const USDC = 'EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v';
const price = await getTokenPrice(USDC);
console.log(`USDC Price: $${price}`);
```

## Rate Limits

| Plan | Calls/Minute | Max Addresses/Request |
|------|--------------|----------------------|
| Demo (Free) | 30 | 30 |
| Analyst | 500 | 50 |
| Lite | 500 | 50 |
| Pro | 1,000 | 100 |
| Enterprise | Custom | Custom |

### Rate Limit Handling

```typescript
class RateLimiter {
  private calls: number[] = [];
  private maxCalls: number;
  private windowMs: number = 60000; // 1 minute

  constructor(maxCallsPerMinute: number) {
    this.maxCalls = maxCallsPerMinute;
  }

  async waitForSlot(): Promise<void> {
    const now = Date.now();
    this.calls = this.calls.filter(t => now - t < this.windowMs);

    if (this.calls.length >= this.maxCalls) {
      const oldestCall = this.calls[0];
      const waitTime = this.windowMs - (now - oldestCall);
      await new Promise(resolve => setTimeout(resolve, waitTime));
    }

    this.calls.push(Date.now());
  }
}

// Usage
const rateLimiter = new RateLimiter(30); // Demo API

async function fetchWithRateLimit(url: string): Promise<any> {
  await rateLimiter.waitForSlot();
  const response = await fetch(url, {
    headers: { [HEADER_KEY]: apiKey },
  });
  return response.json();
}
```

---

## Error Handling

```typescript
async function safeApiCall<T>(url: string): Promise<T | null> {
  try {
    const response = await fetch(url, {
      headers: { [HEADER_KEY]: apiKey },
    });

    if (response.status === 401) {
      throw new Error('Invalid API key');
    }
    if (response.status === 429) {
      throw new Error('Rate limit exceeded - wait before retrying');
    }
    if (response.status === 404) {
      console.warn('Resource not found');
      return null;
    }
    if (!response.ok) {
      throw new Error(`API error: ${response.status}`);
    }

    return response.json();
  } catch (error) {
    console.error('CoinGecko API error:', error);
    throw error;
  }
}
```

### Common Error Codes

| Code | Meaning | Solution |
|------|---------|----------|
| 401 | Invalid API key | Check your API key |
| 429 | Rate limit exceeded | Wait and retry, or upgrade plan |
| 404 | Resource not found | Check address/network ID |
| 500+ | Server error | Retry with exponential backoff |

---

## Best Practices

### Security
- Never commit API keys to git
- Use environment variables
- Rotate keys periodically
- Use separate keys for dev/prod

### Performance
- Batch token requests when possible
- Cache frequently accessed data
- Use appropriate timeframes for OHLCV
- Implement request queuing for rate limits

### Data Quality
- Verify market cap data (may be null if unverified)
- Check pool liquidity before trusting prices
- Use multiple timeframes for price analysis
- Monitor last trade timestamp for activity
