DEX Screener started as a chart UI for tracking DEX activity across chains and grew into the standard token-discovery surface for memecoin traders. The website is more famous than the API, but both are useful for builders.
What you get
- Pairs API. Look up any DEX pair on Solana (or 30+ other chains) by address — get current price, 24h volume, liquidity, FDV, market cap.
- Tokens API. Same data shape, queryable by token address.
- Search. Free-text search across all chains' tokens.
- Embed widgets. One
<iframe>tag drops a fully-functional chart into any page.
Pricing
The public API is currently free with no authentication required. There's a generous rate limit (300 requests per minute on most endpoints) that's enough for the vast majority of dapps. There's no published roadmap for monetization.
When DEX Screener is right
- Multi-chain. Same API shape works across Solana, Ethereum, Base, BSC, Arbitrum, etc. — useful if you're not Solana-only.
- Embedded charts. The iframe widget is the easiest way to put a chart on a page.
- New token coverage. Pump.fun launches show up on DEX Screener within seconds.
- You don't want API keys. Useful for hackathon weekends, public tools, side projects.
When DEX Screener is wrong
- Solana-specific depth. Birdeye has more Solana-native features (token security, holder distributions, Solana-specific OHLCV granularity).
- Production reliability with SLA. The free public API has no SLA. If your business depends on uptime, Birdeye paid is more accountable.
