Introduction

DexScanner is a real-time DEX analytics app — trending pairs, prices, liquidity, volume, charts and risk signals across every major chain. These docs cover the product and the public API.

New here? Start with the product guides to learn the app, or jump to the API if you want to build on the data. Market data is sourced from a public on-chain DEX data API and served through a fast server-side cache.

const pairs = await res.json();
console.log(pairs[0].baseToken.symbol, pairs[0].priceUsd);

🚦 Errors & status codes

Status	Meaning
`200`	Success. Read endpoints degrade gracefully — you may get a recent snapshot or an empty array ([]) rather than an error if data is briefly unavailable.
`403`	Forbidden. Returned by the embed route when embeds are disabled by the site operator.
`429`	Too many requests. You exceeded the rate limit — back off and retry later.
`5xx`	Unexpected server error. Retry after a short delay.
