Validate Your API Node

First, query get_info against your node and confirm the chain_id as well as the server_version_string show the correct values.

Chain ID: 21dcae42c0182200e93f954a074011f9048a7624c6fe81d3c9541a614a88bd1c

Using clio:

/usr/local/bin/clio -u http://localhost:8888 get info

Using curl:

curl -s -X GET 'http://localhost:8888/v1/chain/get_info' | jq '.chain_id'

Next, confirm some of the other FIO API getter calls.

If you are running a V1 History node, confirm access to past transactions through get_actions:

curl --request POST \
     --url http://localhost:8888/v1/history/get_actions \
     --data '{"account_name": "o3vozszmxmto"}'

There is also an advanced FIO table browsing tool called Cryptonym that is useful for testing. You can download Cryptonym from the Blockpane repository.
