eth_getTransactionByBlockNumberAndIndex

Returns information about a transaction given block number and transaction index position.

For Growth and Custom service plans

This JSON-RPC method allows a request to be forwarded to a partner service provider if Infura should experience a service issue or outage. See Failover protection and Enable API request forwarding for complete details.

If you would like failover protection but don't qualify under your current plan, then either self-upgrade to the Growth plan or contact a sales representative to upgrade to a Custom plan.
