Publishing a stream

Everyone is doing it. Here’s how you can add to the list of streams.

1. Python

from microprediction import MicroWriter
mw = MicroWriter(write_key='YOUR WRITE KEY HERE')
mw.set(name='my_stream.json',value=3.14157) 

See publish-using-python for more utilities and patterns.

2. R

library(httr)
httr::PUT(url = paste0("https://api.microprediction.org/live/", 'my_stream.json'),
              body = list(write_key = 'YOUR WRITE KEY HERE', budget = 1, value = 3.1457))

See Fred Viole’s r_examples.

3. Julia

r = HTTP.request("PUT", "https://api.microprediction.org/live/my_stream.json";
query=Dict(
    "write_key" => 'YOUR WRITE KEY',
    value => 3.14157))
JSON.parse(String(r.body))

This example is from Rusty Conover’s Julia Client.

4. API

Send a PUT request to https://api.microprediction.org/live/my_stream.json with the following parameters in the payload:

write_key
budget (can just set to 1)
value (e.g. 3.14157)

Before you publish

Get your writekey of difficulty 12 at least, and learn about bankruptcy.

After you publish

Be patient, keep publishing, and promote your stream.
