# flights (fast-flights)
The fast, robust, strongly-typed Google Flights scraper (API) implemented in Python. Based on Base64-encoded Protobuf string.
```haskell
$ pip install fast-flights
```
</div>
## Usage
To use `fast-flights`, you'll first create a filter (inherited from `?tfs=`) to perform a request.
Then, add `flight_data`, `trip`, `seat` and `passengers` info to use the API directly.
Honorable mention: I like birds. Yes, I like birds.
```python
from fast_flights import FlightData, Passengers, create_filter, get_flights
# Create a new filter
filter = create_filter(
flight_data=[
# Include more if it's not a one-way trip
FlightData(
date="2024-07-02", # Date of departure
from_airport="TPE",
to_airport="MYJ"
),
# ... include more for round trips and multi-city trips
],
trip="one-way", # Trip (round-trip, one-way, multi-city)
seat="economy", # Seat (economy, premium economy, business or first)
passengers=Passengers(
adults=2,
children=1,
infants_in_seat=0,
infants_on_lap=0
),
)
# Get flights with a filter
result = get_flights(filter)
# The price is currently... low/typical/high
print("The price is currently", result.current_price)
# Display the first flight
print(result.flights[0])
```
Additionally, you can use the `Airport` enum to search for airports in code (as you type)! (See `_generated_enum.py` in source)
```python
Airport.TAIPEI
|---------------------------------|
| TAIPEI_SONGSHAN_AIRPORT |
| TAPACHULA_INTERNATIONAL_AIRPORT |
| TAMPA_INTERNATIONAL_AIRPORT |
| ... 5 more |
|---------------------------------|
```
## How it's made
The other day, I was making a chat-interface-based trip recommendation app and wanted to add a feature that can search for flights available for booking. My personal choice is definitely [Google Flights](https://flights.google.com) since Google always has the best and most organized data on the web. Therefore, I searched for APIs on Google.
> 🔎 **Search** <br />
> google flights api
The results? Bad. It seems like they discontinued this service and it now lives in the Graveyard of Google.

Over a decade ago, Google announced the acquisition of ITA Software Inc. which it used to develop its API. **However, in 2018, Google ended access to the public-facing API and now only offers access through the QPX enterprise product**.
That's awful! I've also looked for free alternatives but their rate limits and pricing are just 😬 (not a good fit/deal for everyone).
<br />
However, Google Flights has their UI – [flights.google.com](https://flights.google.com). So, maybe I could just use Developer Tools to log the requests made and just replicate all of that? Undoubtedly not! Their requests are just full of numbers and unreadable text, so that's not the solution.
Perhaps, we could scrape it? I mean, Google allowed many companies like [Serpapi](https://google.com/search?q=serpapi) to scrape their web just pretending like nothing happened... So let's scrape our own.
> 🔎 **Search** <br />
> google flights ~~api~~ scraper pypi
Excluding the ones that are not active, I came across [hugoglvs/google-flights-scraper](https://pypi.org/project/google-flights-scraper) on Pypi. I thought to myself: "aint no way this is the solution!"
I checked hugoglvs's code on [GitHub](https://github.com/hugoglvs/google-flights-scraper), and I immediately detected "playwright," my worst enemy. One word can describe it well: slow. Two words? Extremely slow. What's more, it doesn't even run on the **🗻 Edge** because of configuration errors, missing libraries... etc. I could just reverse [try.playwright.tech](https://try.playwright.tech) and use a better environment, but that's just too risky if they added Cloudflare as an additional security barrier 😳.
Life tells me to never give up. Let's just take a look at their URL params...
```markdown
https://www.google.com/travel/flights/search?tfs=CBwQAhoeEgoyMDI0LTA1LTI4agcIARIDVFBFcgcIARIDTVlKGh4SCjIwMjQtMDUtMzBqBwgBEgNNWUpyBwgBEgNUUEVAAUgBcAGCAQsI____________AZgBAQ&hl=en
```
| Param | Content | My past understanding |
|-------|---------|-----------------------|
| hl | en | Sets the language. |
| tfs | CBwQAhoeEgoyMDI0LTA1LTI4agcIARID… | What is this???? 🤮🤮 |
I removed the `?tfs=` parameter and found out that this is the control of our request! And it looks so base64-y.
If we decode it to raw text, we can still see the dates, but we're not quite there — there's too much unwanted Unicode text.
Or maybe it's some kind of a **data-storing method** Google uses? What if it's something like JSON? Let's look it up.
> 🔎 **Search** <br />
> google's json alternative
> 🐣 **Result**<br />
> Solution: The Power of **Protocol Buffers**

Gotcha, Protobuf! Let's feed it to an online decoder and see how it does:
> 🔎 **Search** <br />
> protobuf decoder
> 🐣 **Result**<br />
> [protobuf-decoder.netlify.app](https://protobuf-decoder.netlify.app)
I then pasted the Base64-encoded string to the decoder and no way! It DID return valid data!
I immediately recognized the values — that's my data, that's my query!
So, I wrote some simple Protobuf code to decode the data.
```protobuf
syntax = "proto3"
message Airport {
string name = 2;
}
message FlightInfo {
string date = 2;
Airport dep_airport = 13;
Airport arr_airport = 14;
}
message GoogleSucks {
repeated FlightInfo = 3;
}
```
It works! Now, I won't consider myself an "experienced Protobuf developer" but rather a complete beginner.
I have no idea what I wrote but... it worked! And here it is, `fast-flights`.
