DexScreener API — Free Multi-Chain DEX Data

DexScreener provides DEX pair data across 80+ chains with no API key required. Prices, volume, liquidity, transaction counts, and token profiles — all free. Best for quick lookups, cross-chain comparison, and lightweight monitoring.

Quick Start

No authentication needed. Just make requests:

import httpx

# Search for a token
resp = httpx.get("https://api.dexscreener.com/latest/dex/search", params={"q": "BONK"})
pairs = resp.json()["pairs"]
for p in pairs[:3]:
    print(f"{p['baseToken']['symbol']}/{p['quoteToken']['symbol']} on {p['chainId']}: ${p['priceUsd']}")

# Or with curl
curl "https://api.dexscreener.com/latest/dex/search?q=BONK"

Base URL

https://api.dexscreener.com

No API key, no headers required. Rate limits: ~300 req/min for DEX data endpoints, 60 req/min for profile/boost endpoints.

Core Endpoints

Search Pairs

# Search by token name, symbol, or address (returns ~30 pairs across all chains)
GET /latest/dex/search?q=BONK
GET /latest/dex/search?q=So11111111111111111111111111111111111111112

Get Pairs by Chain + Pair Address

# Single pair
GET /latest/dex/pairs/solana/PAIR_ADDRESS

# Multiple pairs (comma-separated)
GET /latest/dex/pairs/solana/PAIR1,PAIR2,PAIR3

Get Pairs by Token Address

# All pairs containing this token across all chains
GET /latest/dex/tokens/TOKEN_MINT_ADDRESS

# Chain-specific (v1)
GET /token-pairs/v1/solana/TOKEN_MINT

# Multiple tokens on one chain (v1)
GET /tokens/v1/solana/TOKEN1,TOKEN2,TOKEN3

Token Profiles & Boosts

# Latest token profiles (60 req/min)

# Latest boosted tokens
GET /token-boosts/latest/v1

# Top boosted tokens (sorted by total boost amount)

Pair Response Schema

{
  "chainId": "solana",
  "dexId": "raydium",
  "url": "https://dexscreener.com/solana/PAIR_ADDR",
  "pairAddress": "3nMFwZX...",
  "labels": ["CLMM"],
  "baseToken": { "address": "So11...", "name": "Wrapped SOL", "symbol": "SOL" },
  "quoteToken": { "address": "EPjF...", "name": "USD Coin", "symbol": "USDC" },
  "priceNative": "86.08",
   
   
           
           
           
          
  
            
            
          
   
   
   
   
     
          
          
  

Key notes:

• priceNative and priceUsd are strings (preserves precision)
• pairCreatedAt is milliseconds (divide by 1000 for unix timestamp)
• labels: "CLMM" (concentrated), "DLMM" (dynamic), "wp" (whirlpool)
• info is optional — only present if the token profile has been claimed
• fdv/marketCap may be absent for tokens without supply data

Common Patterns

Quick Token Lookup

def lookup_token(address: str) -> dict | None:
    """Get the best pair for a token by liquidity."""
    resp = httpx.get(f"https://api.dexscreener.com/latest/dex/tokens/{address}")
    pairs = resp.json().get("pairs", [])
    if not pairs:
        return None
    # Sort by liquidity (highest first)
    pairs.sort(key=lambda p: p.get("liquidity", {}).get("usd", 0), reverse=True)
    return pairs[0]

Cross-Chain Price Check

def find_best_price(symbol: str) -> list[dict]:
    """Find a token across all chains and compare prices."""
    resp = httpx.get("https://api.dexscreener.com/latest/dex/search", params={"q": symbol})
    pairs = resp.json().get("pairs", [])
    results = []
    for p in pairs:
        if p["baseToken"]["symbol"].upper() == symbol.upper():
            results.append({
                "chain": p["chainId"],
                "dex": p["dexId"],
                "price": float(p.get("priceUsd", 0)),
                "liquidity": p.get("liquidity", {}).get("usd", 0),
                "volume_24h": p.get("volume", {}).get("h24", 0),
            })
    return sorted(results, key=lambda x: x["liquidity"], reverse=True)

Monitor New Tokens via Boosts

def get_newly_boosted() -> list[dict]:
    """Get tokens that were recently boosted (paid promotion)."""
    resp = httpx.get("https://api.dexscreener.com/token-boosts/latest/v1")
    return [
        {
            "chain": t["chainId"],
            "address": t["tokenAddress"],
            "boost_amount": t.get("amount", 0),
            "total_boost": t.get("totalAmount", 0),
            "description": t.get("description", ""),
        }
        for t in resp.json()
    ]

Buy/Sell Ratio Analysis

def analyze_pressure(pair: dict) -> dict:
    """Analyze buy/sell pressure from transaction counts."""
    txns = pair.get("txns", {})
    result = {}
    for tf in ["m5", "h1", "h6", "h24"]:
        data = txns.get(tf, {})
        buys = data.get("buys", 0)
        sells = data.get("sells", 0)
        total = buys + sells
        result[tf] = {
            "buys": buys, "sells": sells, "total": total,
            "buy_ratio": buys / total if total > 0 else 0.5,
        }
    return result

Supported Chains

Major chains: solana, ethereum, base, arbitrum, bsc, polygon, avalanche, optimism, zksync, scroll, linea, tron, near, aptos, ton, sui, hyperliquid

80+ chains total. The chainId matches the URL path on dexscreener.com.

Limitations

• No OHLCV/candle data — Use Birdeye or SolanaTracker for historical candles
• No pagination — Search returns ~30 results max
• No wallet/trader data — Use Birdeye or Helius for wallet analysis
• No token security data — Use Birdeye token_security endpoint
• Snapshot data only — Current state, not historical time series
• No WebSocket — Polling only
