[beem](https://github.com/holgern/beem) is a python library for steem.  The current version is 0.20.23.

There is also a discord channel for beem: https://discord.gg/4HM592V

The newest beem version can be installed by:

```
pip install -U beem
```

## Changelog

* Switch to next node, when current node has the necesary api not enabled
* handle Client returned invalid format. Expected JSON! and switch to next node
* More checks added
* get_estimated_block_num is faster and uses BlockHeader
* exclude_limited=False is default now for get_nodes

## Switching automatically to the next node on `ApiNotSupported` errors
At the moment, the full nodes have some problems and a lot nodes have disabled some apis. beem can now handle this and is automatically switching to the next node in the list.

```
from beem.account import Account
from beem import Steem
stm = Steem("https://steemd.minnowsupportproject.org")
account = Account("steemit", steem_instance=stm)
print(account.get_blog(0, 1))
```
returns the error:
```
beemapi.exceptions.ApiNotSupported: Assert Exception:api_itr != _registered_apis.end(): Could not find API follow_api
```
As there is only one node given, beem cannot switch to then next node.
When using a node list instead:


```
from beem.account import Account
from beem import Steem
from beem.nodelist import NodeList
nodelist = NodeList()
stm = Steem(node=nodelist .get_nodes())
account = Account("steemit", steem_instance=stm)
print(account.get_blog(0, 1))
```
the script returns:
```
Error: Assert Exception:api_itr != _registered_apis.end(): Could not find API follow_api
Lost connection or internal error on node: https://steemd.minnowsupportproject.org (1/100) 

[<Comment @steemit/firstpost>]
```
which means that first failing with https://steemd.minnowsupportproject.org, but then retrying sucessfully with https://rpc.usesteem.com.

## Using update_nodes

The following nodes are currently stored in NodeList:
```
from beem.nodelist import NodeList
nodelist = NodeList()
print(nodelist .get_nodes())
```
the following nodes are returned:
```
['https://steemd.minnowsupportproject.org', 'https://rpc.usesteem.com', 'https://anyx.io', 'https://api.steemit.com', 'https://steemd.privex.io', 'http://anyx.io', 'https://appbasetest.timcliff.com', 'https://api.steem.house']
```

```
from beem.nodelist import NodeList
nodelist = NodeList()
nodelist.update_nodes()
print(nodelist .get_nodes())
```

`nodelist.update_nodes()` fetches the currently working nodelist from @fullnodeupdate. I'm writing a fullnode benchmark every 3 hours to this account, which can be obtained from the json_metadata field.

Currently the following nodes are working:
```
['http://anyx.io', 'https://anyx.io', 'https://steemd.minnowsupportproject.org', 'https://api.steemit.com', 'https://rpc.usesteem.com', 'https://api.steem.house', 'https://steemd.privex.io']

```
