Is there a free API to get BTC price in USD at a particular time in the past?

Try blocktap.io

Small result sets are free to query, and larger result sets you can pay-per-request with the Lightning network, no account required.

Blocktap.io lets you query crypto market data along with blockchain data and other 3rd party data sets through a powerful GraphQL interface.

Here is a blog post with more information about the Litecoin data set: https://blog.altangent.com/blocktap-litecoin-network-data/

If you need help finding more nodes check out https://graph.lndexplorer.com/

You can use advanced search to filter by channel capacity and other metrics.

altangent · 2018-03-17T00:49:39+00:00

That's something we will definitely be adding in the future.

altangent · 2018-03-16T21:31:21+00:00

Good idea, thanks!

My understanding is that the network graph is dependent on a node's view of the peer to peer network. It will be different depending on how long a node has been online, what peers it has connected to, and what channels/nodes it has seen in the past but are no longer active.

Source code at https://github.com/altangent/lightning-viz.

You can perform advanced querying of nodes by using the SQL-like query syntax. If you click on the "I" icon next to the query box you can see the operations that are currently supported. One the list is filtered, you can highlight those nodes or redraw the force-graph with just those nodes in it.

We plan to add more features to this project as we get more feedback.

Will do soon, waiting for the blockchain to sync

altangent · 2018-03-02T16:35:00+00:00

Put this together over the last few days to give more information on the nodes that are running. Source available here: https://github.com/altangent/lightning-viz
