Example

Request from Linux:

curl -X POST -H 'content-type: application/json' -d '{"address":"0xb47ce3a95c5062d9f5894862dcc44df7a660dfba", "from":"1659880849", "to":"1659884449"}' http://localhost:3000/transfers

Request from Windows (it is needed to escape " symbol):

curl -X POST -H 'content-type: application/json' -d '{\"address\":\"0xb47ce3a95c5062d9f5894862dcc44df7a660dfba\", \"from\":\"1659880849\", \"to\":\"1659884449\"}' http://localhost:3000/transfers

Server start

In order to start the server:

python3 main.py

This command starts a server listening on port 3000.
The cache on the server will retain data for 30 seconds.
The queries to the Ethereum blockchain will be sent to node https://aged-wispy-sun.quiknode.pro/a9c866c62d28d63303de21fd44e95f747f725857

Server configuration

Use following paramaters to configure the server:

• port / p
• cache-time / ct
• node-url / nu

It is possible to change the port, the Ethereum node url or the cache retention time using the previously enumerated parameters.

Config example

python3 main.py p 3002 ct 100 nu 'https://wild-divinemoon.quiknode.pro/9a2fc33e00169e941e01396b0b5a31cf8bc3ab16/'

Known limitations

Cache not valid data are retained inside memory unless a request for that data is received. This could lead to very big chunck of cache used for not valid data if a lot of non repetitive commands are received.
