# Fundi Scraper API

A small REST API (FastAPI) that serves the events scraped by
[`scraper/scraper.py`](../scraper/scraper.py) from a JSON file.

## Setup

```bash
cd api
pip install -r requirements.txt
```

## Run

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

Interactive docs: http://127.0.0.1:8000/docs

By default the API reads `../fundi-scraped-output.json` (upcoming events) and
`../fundi-archive-output.json` (past events, optional — produced by
`scraper.py --archive`), merging both into one in-memory list. Point either
elsewhere with an env var:

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

### Scrape schedule reporting

`/health` reports when each scraper output file was last written (its mtime)
and, if you tell it the cron schedule, when it's next due. This doesn't read
your crontab — set the same expression(s) you put there as env vars:

```bash
SCRAPE_CRON="0 * * * *" ARCHIVE_SCRAPE_CRON="0 4 * * *" uvicorn main:app
```

`SCRAPE_CRON` covers the plain scrape (`fundi-scraped-output.json`);
`ARCHIVE_SCRAPE_CRON` covers `--archive` (`fundi-archive-output.json`) and
falls back to `SCRAPE_CRON` if unset — set it separately only if the archive
scrape runs on its own cron line. Leave both unset to just get the
last-scrape info with `next_scrape_at` / `seconds_until_next_scrape` as
`null`.

## Endpoints

| Method | Path              | Description |
|--------|-------------------|-------------|
| GET    | `/health`         | Status, event counts, and last/next scrape timing (see below) |
| GET    | `/events`         | List events, with optional filters (see below) |
| GET    | `/events/archive` | Past events only — shorthand for `/events?upcoming=false` |
| GET    | `/events/{index}` | Single event by its position in the merged list (0-based) |
| GET    | `/artists`        | Deduplicated, sorted list of all artist names |
| GET    | `/calendar.ics`   | iCalendar/webcal feed of all events — subscribe with `webcal://<host>/calendar.ics` |
| POST   | `/reload`         | Re-read the data file(s) from disk (after a fresh scrape) |

### `/events` query parameters

| Param      | Type   | Meaning |
|------------|--------|---------|
| `free`     | bool   | Only free / only paid events |
| `name`     | string | Case-insensitive substring match on the event name |
| `artist`   | string | Case-insensitive substring match on any artist name |
| `date`     | string | Exact match on the raw date string (`dd.mm.yy`) |
| `upcoming` | bool   | `true` = today or later, `false` = past events |

Examples:

```bash
curl 'http://127.0.0.1:8000/events?free=true'
curl 'http://127.0.0.1:8000/events?artist=randali&upcoming=true'
curl 'http://127.0.0.1:8000/events/0'
