I am excited to share the initial release of [PolygonIO.jl](https://github.com/PyDataBlog/PolygonIO.jl). PolygonIO.jl aims to enrich Julia finance ecosystem with full coverage of all the REST API and websocket services provided by the popular financial data platform - [Polygon io](https://polygon.io/).

**Main Features**

- Full coverage of Stock API
- Full coverage of Forex API
- Full coverage of Crypto API
- Full coverage of Reference Data API
- Full coverage of WebSocket API

**Example**

```julia
using PolygonIO
using DataFrames

opts = PolyOpts(API_KEY, DataFrame)
ticker_search_info = tickers(opts, "bitcoin")

```

```julia
julia> ticker_search_info = tickers(opts, "bitcoin")
10×10 DataFrame
 Row │ ticker name market locale active currency_symbol currency_name base_curre ⋯
     │ String String String String Bool String String String ⋯
─────┼────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────
   1 │ X:BSVUSD Bitcoin SV - United States Dollar crypto global true USD United States Dollar BSV ⋯

                                                                                                                 3 columns omitted

```

Any form of feedback will be greatly appreciated.

How about Polygonio\_IO? That will make it clear that it is not another geometry IO package.

To your point, from the name I did assume it was a package for reading shapefiles, wkt, … etc.

Hmmm never considered that naming effect. I will probably hit up the registry team up to see if a name switch was possible.

do you have options data? I’m interested in Implied volatility. Nice work.

I plan on adding the options API. I have just seen it.

This name is really misleading. No polygons are involved, as I finally gleaned from the repo website.

OUTSTANDING!!! We’ve just been looking at [Polygon.io](http://Polygon.io) as a source of test data for our trading augmentation tool. WELL DONE getting this up and running. We use Implied volatility as a metric and you might have made doing this VERY easy. As to the name change, could I suggest DeadParrot.jl 🙂

I will also have to look into the name changing request to avoid any confusion.

The service is called [Polygon.io](http://Polygon.io) so I don’t see how the package is improperly named. If it is misleading, that is not your fault. The post itself makes very clear what the package does

</div>

That was the main reason why I settled on that name. Named after the service.

@PyDataBlog huge FAN!!! Never mind what this ends up being called ( deadparrot.jl 🙂 ) I’m going to be using it in my first julia program. It’s EXACTLY what I have been looking for. Marry your package with Pluto.jl, Dagger.jl, my laziness and we have a 2022 project. OUTSTANDING!  
thanks again
