curl -X POST https://api.quantumapi.io/v1/rpc \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"qc_getBlockByHash","params":["0xabc...123", true],"id":1}'

qc_getHeaderByNumber

Returns a block header by number.

Parameter	Type	Description

curl -X POST https://api.quantumapi.io/v1/rpc \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"qc_getHeaderByNumber","params":["latest"],"id":1}'

qc_getHeaderByHash

Returns a block header by its hash.

Parameter	Type	Description
`blockHash`	`string`	32-byte block hash (hex)

curl -X POST https://api.quantumapi.io/v1/rpc \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"qc_getHeaderByHash","params":["0xabc...123"],"id":1}'

qc_getUncleCountByBlockNumber

Returns the number of uncles in a block by block number.
