Reverse engineering [dexscreener](https://dexscreener.com) avro encryption to fit my web scraping needs

Before running the api, make sure you have node >= v18 installed

## Running the api

```bash

npm install

node main.js

```

## Using Docker

```bash

docker build -t dexscreener:v1 .

docker run -d --name dexscreener-api -p 3000:3000 dexscreener:v1

```

## Sending requests

There are 2 important endpoints:

- GET `/pairs` - use query parameter `q` to pass token address

This endpoint is called on dexscreener.com when you try to search token pairs, it returns the decrypted results as json

- GET `/logs` - supported query parameters: `q` for token address, `m` for wallet hash and `c` which should be set to `1`. 

For pagination, if you want to get results above page 1, set query parameter `bbn` `blockNumber` to value which is returned by previous page (`blockNumber` field)

Get transaction logs of a wallet in a pool (including summary data)
