• /v1.0/tokens - returns known tokens (ethereum, aptos)
• /v1.0/blocks/lastest - returns the last block number
• /v1.0/blocks/<block_number> - returns block data for the given block number
• /v1.0/blocks/<block_hash> - returns block data for the given block hash
• /v1.0/transactions/<transaction_hash> - returns transaction data for the given transaction hash

# the following are necessary only you are running multiple deployments
# using different redises to synchronize limits
SIDECAR_TOKEN=<sidecar token> 
SIDECAR_URLS='[<http://another-sidecar-url.com/>]'
