Overview

cryptotsla calculates the current Bitcoin spot price of a specific Tesla vehicle configuration, optionally taking a currency and regionally available Tesla vehicle configurations into account.

The information is made available via a JSON API that can be queried via http, e.g.:

curl -s "https://api.cryptotsla.com/model/Y" |jq .
{
  "Model": "Y",
  "BasePrice": 41990,
  "Variant": "StandardRange",
  "Options": {
    "DestinationFee": 1200
  },
  "BTCSpotPrice": "48026.86",
  "Currency": "USD",
  "Total": 43190,
  "TotalBTC": "0.8992884398438707",
  "GeneratedByURL": "https://api.cryptotsla.com",
  "Timestamp": "2021-02-15T17:28:59.903489389-05:00"
}

To get just the BTC total:

curl -s "https://api.cryptotsla.com/model/Y"  |jq .TotalBTC
0.8992884398438707

The default model Y variant, "StandardRange", was selected automatically. To request a different variant:

curl -s "https://api.cryptotsla.com/model/Y/LongRange" |jq .
{
  "Model": "Y",
  "BasePrice": 49990,
  "Variant": "LongRange",
  "Options": {
    "DestinationFee": 1200
  },
  "BTCSpotPrice": "48192.08",
  "Currency": "USD",
  "Total": 51190,
  "TotalBTC": "1.0622077320588777",
  "GeneratedByURL": "https://api.cryptotsla.com",
  "Timestamp": "2021-02-15T17:36:50.646497513-05:00"
}

It is also possible to specify vehicle options:

curl -s "https://api.cryptotsla.com/model/Y/LongRange?options=TowHitch,SevenSeatInterior" |jq .
{
  "Model": "Y",
  "BasePrice": 49990,
  "Variant": "LongRange",
  "Options": {
    "DestinationFee": 1200,
    "SevenSeatInterior": 3000,
    "TowHitch": 1000
  },
  "BTCSpotPrice": "48108.21",
  "Currency": "USD",
  "Total": 55190,
  "TotalBTC": "1.147205435413207",
  "GeneratedByURL": "https://api.cryptotsla.com",
  "Timestamp": "2021-02-15T17:37:36.980907053-05:00"
}

If an option is requested that does not exist, it will be ignored. Some options only exist in certain territories and will only be included when the relevant currency is selected.

A different currency can be selected. This also limits the response to the models, variants and options available in the relevant territory, for example:

curl -s "https://api.cryptotsla.com/model/3/LongRange?options=Red&currency=GBP" |jq .
{
  "Model": "3",
  "BasePrice": 46990,
  "Variant": "LongRange",
  "Options": {
    "Red": 2000
  },
  "BTCSpotPrice": "34697.26",
  "Currency": "GBP",
  "Total": 48990,
  "TotalBTC": "1.4119270513003044",
  "GeneratedByURL": "https://api.cryptotsla.com",
  "Timestamp": "2021-02-15T17:50:49.112942967-05:00"
}

Model, variant and option names are case insensitive.

Room for improvement

There is no BTC-CAD order book via this Coinbase API. Use a different API? The Coinbase developer API seems to have a price endpoint for CAD.
We need some sort of locale option. Particularly for the Euro pricing, where there are differences between the countries that use the Euro.
Many currencies are missing from config.yml.example
