DEX Screener vs GeckoTerminal

The two free APIs are free in opposite directions

Both products are free to read, both cover DEX pairs across many chains, both draw their price charts with a licensed TradingView build rather than their own renderer, and both are open in a browser on most memecoin desks at the same time. On the screen they are close enough that the choice looks like taste.

They stop being close the moment you call them from code, and the split is not subtle:

• DEX Screener — no key, 300 requests a minute on the pair, token, search and token-pairs endpoints, 60 on the promotional ones. No candle or history endpoint documented anywhere.
• GeckoTerminal — no key, approximately 10 requests a minute, and it has OHLCV.

Thirty times the throughput on one side, the thing you would build a chart out of on the other. That is the whole comparison, and it is not an accident of engineering.

It follows from who the customer is

Neither company is charging you, so both are charging somebody, and the somebody is different.

DEX Screener sells promotion on the screen. Enhanced Token Info starts at 299 dollars, banner advertising at 299, a trending-bar slot at 2,000, and Boost packs multiply a token's Trending Score for twelve to twenty-four hours. The reader is not the customer — the token team is. A generous, keyless, high-throughput API costs that business model almost nothing and helps it: more surfaces showing DEX Screener data is more distribution for the tokens paying to appear in it. Candles would not help, so there are none.

GeckoTerminal sells API calls. The identical on-chain feed is also the /onchain half of the CoinGecko API, where a paid plan raises the limit from roughly 10 a minute to 250 — twenty-five times — and unlocks parameters the free tier marks "Pro API only". The free beta is the demo, and 10 calls a minute is what a demo is set to. It has candles because candles are what the paid product is bought for.

So the free tiers are not two attempts at the same thing with different budgets. Each is exactly the shape its owner's revenue requires, and reading them as competing generosity gets the decision backwards.

Where the cards disagree, and where they do not

Both cards were verified on 19 September 2026, so nothing here rests on readings months apart. The chain counts are counted rather than quoted — 64 chains read off DEX Screener's live rail, 228 networks confirmed by paging GeckoTerminal's own /networks endpoint to exhaustion — and they are not measuring quite the same thing, because "network" and "chain" are the vendors' words, not ours.

The one place the two cards genuinely disagree is alerts. DEX Screener has them and they are free. GeckoTerminal's card records alerts: false after reading the navigation, the pool page and the watchlist panel, and says so as a bounded negative rather than a certainty. If alerts decide it for you, check before you commit.

The axis where the smaller product wins outright

DEX Screener loses on chains, loses on DEX count, and loses on having no candles. It wins on one thing and the win is large: polling many pairs' current state, free, forever, without a key, at 300 requests a minute.

That is not a consolation prize. A dashboard that refreshes the live price, liquidity and twenty-four-hour volume of two hundred pairs every minute is a completely ordinary thing to want, and it is comfortable on DEX Screener and impossible on GeckoTerminal's free tier — 10 calls a minute will not refresh two hundred of anything. The moment your question is "what is happening right now, across a lot of pairs", the ranking inverts.

It also has no upgrade path at all, which cuts both ways. Nobody will ever send you a bill, and nobody will ever raise your limit.

What to use

If you will ever touch it from code, start with GeckoTerminal and assume a CoinGecko plan is in your future. The reason is not the rate limit, which you can work around, and not the chain count, which you probably do not need. It is OHLCV: history is the one thing DEX Screener does not sell, lend or throttle — it simply does not have it, and no amount of throughput substitutes for a candle.

Switch to DEX Screener the moment the job is breadth of live state rather than depth of history — a watchlist, a liquidity monitor, a board of two hundred pairs refreshed every minute. Thirty times the free throughput is decisive there, and the absent candle endpoint costs you nothing because you were not asking for candles.

Read DEX Screener's trending row as advertising in either case. That is not a reason to avoid the product; it is a reason to know which parts of it are editorial and which are inventory. On GeckoTerminal the equivalent caution is different and quieter — nothing on the screen is for sale, and the pressure shows up later, as a rate limit you are meant to want to escape.
