Nektar Module

Import Module

from nektar import Waggle

Basic Setup

from nektar import Waggle

username = "hive-username"
app = "nectar.app"
version = "2022.10.05"

hive = Waggle(username)

Setup Application

username = "hive-nektar"
app_name = "nektar.app"
version = "2022.10.05"

hive = Waggle(username, app=app_name, version=version)

Setup Application with WIF/s

app_name = "nektar.app"
version = "2022.10.05"

hive = Waggle(username, app=app_name, version=version)

wifs = [ "5*" ]

hive.append_wif(wifs)

Browse Communities

## get up to 200 communities by rank
communities = hive.communities(limit=200)
for community in communities:
    print(community["name"] + "\t" + community["title"])

communities = {}
sorting = ["new", "rank", "subs"]
for sort in sorting:
    ## get up to 1000 communities per sorting filter
    for community in hive.communities(sort=sort):
        communities.update({community["name"]: community})

Get Posts in a Community Get posts in a community by sorting filter created, trending, hot, promoted, payout, payout_comments, or muted.

community = "hive-1*"  # supply with a valid community name
posts = hive.posts(community, limit=100, sort="created")
print(posts[0]["author"])
print(posts[0]["permlink"])
print(posts[0]["title"])

Get Posts with a Tag Get posts in a community by sorting filter: created, trending, hot, promoted, payout, payout_comments, or muted.

tag = "nature"
posts = hive.posts(tag, limit=10, sort="created")
for post in posts:
    print(post["title"])

Get Community Sunscribers

subscribers = {}
community = "hive-1*"  # supply with a valid community name
for subscriber in hive.subscribers(community, limit=1000):
    subscribers.update({subscriber[0]: subscriber})
    print(subscriber[0])

Search Accounts Starting with a pattern

accounts = hive.accounts(start="h", limit=1000)

Get the List of Followers

## followers of the initialized account
followers = hive.followers()
print(followers)

## or using a valid account username
followers = hive.followers(account="valid-username")
print(followers)

Get the List of Delegators

## followers of the initialized account
delegators = hive.delegators()
for delegator, data in delegators.items():
    print(delegator)
    for dt, vests in data.items():
        print(dt, vests)


## or using a valid account username
delegators = hive.delegators("valid-username")
for delegator, data in delegators.items():
    print(delegator)
    for dt, vests in data.items():
        print(dt, vests)

## only show active delegations
delegators = hive.delegators(active=True)
for delegator, vests in delegators.items():
    print(delegator, vests)

Get the List of Delegatees

## followers of the initialized account
delegatees = hive.delegatees()
for delegatee, data in delegatees.items():
    print(delegatee)
    for dt, vests in data.items():
        print(dt, vests)


## or using a valid account username
delegatees = hive.delegatees("valid-username")
for delegatee, data in delegatees.items():
    print(delegatee)
    for dt, vests in data.items():
        print(dt, vests)

## only show active delegations
delegatees = hive.delegatees(active=True)
for delegatee, vests in delegatees.items():
    print(delegatee, vests)

Get Blog Posts Get posts of an account by sorting filter: blog, feed, post, replies, or payout

## blog posts of the initialized account
blogs = hive.blogs(limit=10)
for blog in blogs:
    for key, value in blog.items():
        print(key + ":", value)
        
## customized blog search from another account
blogs = hive.blogs(account="valid-username", sort="blog")
for blog in blogs:
    for key, value in blog.items():
        print(key + ":", value)

Access a Blog Post/Comment If the post or comment does not exists in the blockchain, it will return an empty dictionary.

author = "valid-username"
permlink = "valid-permlink"
data = hive.get_post(author, permlink)
print(json.dumps(data, indent=4))
    
author = "valid-username"
permlink = "test-permlink-abc-123-def-456"
data = hive.get_post(author, permlink, retries=5)
if not data:
    print("The post is not yet in the blockchain.")

Create a Post Programmatically

title = "Make Your Title Catchy, But Not ClickBait-y"
body =  "# This is a header\n\n" \
        "## Adding a `h2` Header" \
        "![Image Caption](https://image.link.goes/here)\n\n" \
        "<center>How to center a text?</center>\n\n" \
        "This is how to make it *itzlic*, **bold**, or ***both***!\n\n" \

description = "My first blog using Nektar!"
tags = "devtalk nektar hive api coderundebug"
community = "hive-1*"  # use a valid community name

hive.new_post(title, body, description, tags, community)

Vote on A Post

author = ""
permlink = ""
weight = 10000  # -10000 to 10000, where 1000 = 100%

hive.vote(author, permlink, weight)

Send a Memo

receiver = "valid-username"
amount = 0.001
asset = "HBD"
message = "Sending you some HBDs..."
hive.memo(receiver, amount, asset, message)

Create a Custom JSON (Active Key)

protocol_id = "nektar_admin"
json_data = { "app": "nektar.app/2022.10.05" }
required_auths = ["valid-username"]
required_posting_auths = []
hive.custom_json(protocol_id, json_data, required_auths, required_posting_auths)

AppBase Module

Basic Usage

from appbase import AppBase

hive = AppBase(username)
hive.append_wif("5*")

props = hive.api("database").get_dynamic_global_properties({})

username = "nektar"
account = hive.api("condenser").get_accounts([[self.username]])
