🔑 Authorization

To start using DexGuru API, all you need is an API key. Go to developers.dex.guru, connect your web3 wallet, create a project, and copy your API key. This API key is all you need to start receiving reliable on-chain trading data on multiple EVM-compatible networks.

There are two ways to authorize your API request. Instead of YOUR_API_KEY, use the key you got at developers.dex.guru:

Query Parameter
ex: curl https://api.dev.dex.guru/v1/chain/?api-key=YOUR_API_KEY

Authorization Header
ex: curl https://api.dev.dex.guru/v1/chain/ -H 'api-key: YOUR_API_KEY'

📈 FAQ

Q: Why can I not access all historical data about a certain token?
A: For the time being, for every DEX/AMM that is added onto DexGuru, we currently index and display transaction data only from the date/time they are implemented. This means for all transactions (and their TX data) that have occurred before the date of the DEX/AMM implementation date, will not be included in transaction lists, aggregates/counts, and charts that involve the pre-implementation time period. You can find the list of DEXs and when they were added at https://docs.dex.guru/data/supported-dexs-amms

Q: How often data is updated?
A: Currently for Free Tier Plan there is a 300 seconds delay on all on-chain data.

Q: Am I sending too many requests?
A: The rate limit is 5 concurrent requests per second.

Q: I only receive 20 transactions in the response. How can I look at older transactions?
A: Use "limit" and "offset" query parameters to use pagination. Using the "offset" parameter you can specify where to start a page. Using the "limit" parameter you can specify the page size.

Some parameters can be unclear. Below are their descriptions.
chain_id - You can look up chainID for any EVM powered network by going to https://chainlist.org/.

verified - We use Token Lists to identify verified tokens. A token is considered verified if present in at least one Token List. For ERC-20 tokens we use https://tokenlists.org/. For more info go to https://docs.dex.guru/data/off-chain-data-usage#usage-of-token-lists.

limit - This is a parameter used for pagination. Use it to specify the page size. Learn more about pagination here
