# fundi-scraper-api

Simple scraper that turns all upcoming and past events at the
[Fundbureau](https://fundbureau.de/) (Hamburg) into a REST API — a small project
for a bored afternoon in my hometown, and handy for asking a voice assistant
what's coming up.

Two parts:

1. **`scraper/`** — a Playwright + BeautifulSoup script that scrapes the
   Fundbureau site and writes the events to a JSON file.
2. **`api/`** — a FastAPI app that serves that JSON file as a REST API.

```
fundbureau.de  ──scraper──▶  fundi-scraped-output.json  ──api──▶  REST endpoints
```

## Requirements

- Python 3.11+
- For the scraper: `playwright`, `beautifulsoup4` (plus `playwright install chromium`)
- For the API: `fastapi`, `uvicorn` (see [`api/requirements.txt`](api/requirements.txt))

```bash
pip install beautifulsoup4 playwright
playwright install chromium
pip install -r api/requirements.txt
```

## 1. Scraper

Located in [`scraper/scraper.py`](scraper/scraper.py). Run it from the repo root:

```bash
python scraper/scraper.py
```

This writes `fundi-scraped-output.json` to the current directory.

### Options

| Flag | Description | Default |
|------|-------------|---------|
| `--url URL` | URL to scrape | `https://fundbureau.de/` |
| `--output-file NAME` | Output JSON file name | `fundi-scraped-output.json` |
| `--output-path PATH` | Directory for the output file | `./` |
| `--load-local-file` | Parse a local HTML file instead of scraping the live site (pass the file path as `--url`) | off |
| `--ignore-ticket-link` | Don't extract ticket links; leaves `event_ticket_link` empty and `event_free` null | off |

### Output format

The output is a JSON array of event objects:

```json
[
  {
    "event_date": "04.09.26",
    "event_name": "Trance",
    "event_artists": [
      [
        { "artist_name": "Skkin Velvet", "artist_play_time_start": "0",  "artist_play_time_end": "Open end" },
        { "artist_name": "Bizarre",      "artist_play_time_start": "23", "artist_play_time_end": "3" }
      ]
    ],
    "event_starttime": "EINLASS 23:00",
    "event_ticket_link": "https://www.ticketmaster.de/venue/fundbureau-hamburg-tickets/hamfundb/701",
    "event_free": false
  }
]
```

| Field | Type | Notes |
|-------|------|-------|
| `event_date` | string | `dd.mm.yy` |
| `event_name` | string | |
| `event_artists` | array of arrays of objects | outer array is the line-up grouping; each artist has `artist_name`, `artist_play_time_start`, `artist_play_time_end` (times are hours as strings, `"n/a"`, or `"Open end"`) |
| `event_starttime` | string | raw door-time text, e.g. `"EINLASS 23:00"` |
| `event_ticket_link` | string | URL, or `"n/a"` for free events, or `""` if unknown |
| `event_free` | bool \| null | `true` if admission is free, `null` when `--ignore-ticket-link` is used |

## 2. REST API

Located in [`api/`](api/). It loads a scraped JSON file into memory and exposes it
over HTTP.

### Run

```bash
cd api
uvicorn main:app --reload
```

- API root: http://127.0.0.1:8000
- Interactive docs (Swagger UI): http://127.0.0.1:8000/docs
- OpenAPI schema: http://127.0.0.1:8000/openapi.json

By default the API reads `fundi-scraped-output.json` from the repo root. Override
with the `DATA_FILE` environment variable:

```bash
DATA_FILE=/path/to/events.json uvicorn main:app
```

### Endpoints

| Method | Path | Description |
|--------|------|-------------|
| `GET`  | `/health` | Service status, number of events loaded, resolved data file path |
| `GET`  | `/events` | List events, with optional filters (below) |
| `GET`  | `/events/{index}` | A single event by its 0-based position in the file; `404` if out of range |
| `GET`  | `/artists` | Deduplicated, case-insensitively sorted list of all artist names |
| `POST` | `/reload` | Re-read the JSON file from disk (call after re-running the scraper); `500` if the file is missing |

### `/events` query parameters

All filters are optional and combine with AND.

| Param | Type | Meaning |
|-------|------|---------|
| `free` | bool | `true` = only free events, `false` = only paid events |
| `name` | string | Case-insensitive substring match on `event_name` |
| `artist` | string | Case-insensitive substring match on any artist name in the line-up |
| `date` | string | Exact match on the raw `event_date` string (`dd.mm.yy`) |
| `upcoming` | bool | `true` = event date is today or later, `false` = past events (events with an unparseable date are excluded) |

### Response shapes

`GET /events` returns:

```json
{
  "count": 2,
  "events": [ { "event_date": "…", "event_name": "…", "...": "…" } ]
}
```

`GET /events/{index}` returns a single event object (same schema as the scraper
output). `GET /artists` returns a plain JSON array of strings.

### Examples

```bash
# All events
curl http://127.0.0.1:8000/events

# Only free events
curl 'http://127.0.0.1:8000/events?free=true'

# Upcoming events featuring an artist whose name contains "randali"
curl 'http://127.0.0.1:8000/events?artist=randali&upcoming=true'

# Everything on a given night
curl 'http://127.0.0.1:8000/events?date=05.09.26'

# First event in the file
curl http://127.0.0.1:8000/events/0

# All known artists
curl http://127.0.0.1:8000/artists

# Refresh after re-scraping
python scraper/scraper.py && curl -X POST http://127.0.0.1:8000/reload
```

## Typical workflow

```bash
# 1. Scrape
python scraper/scraper.py

# 2. Serve
cd api && uvicorn main:app --reload

# 3. (later) re-scrape and hot-reload the API without restarting it
python scraper/scraper.py
curl -X POST http://127.0.0.1:8000/reload
```
