is it possible to get webhooks for uniswap info (swaps/sells etc)

Yesterday we've launched sim.io which enables anyone to create applications and data pipelines that rely on blockchain data.. 

A core part of sim is the EVM Lambda, the EVM Lambda allows anyone to create hooks that intercept EVM executions and get callbacks for running your own off-chain code. Here is a short example of how one could use an EVM Lambda to track ownership changes for @openzeppelin Ownable contracts!

The EVM Lambda enables you to hook/intercept and target:
- Calls/internal calls to/from address
- Any contracts matching specific ABIs
- Function execution/log emission
- Transactions
- Block start/end
- Storage operations

Currently, Lambdas are written in Solidity and enhanced by simFunctions, enabling capabilities beyond standard EVM and Solidity limitations. In the coming months, you'll be able to write Lambdas in any language that compiles to WASM.
