# weatherapi

`weatherapi` is a small HTTP API that serves weather data backed by the
PostgreSQL schema populated by `weatherfeeder`.

## Config

`weatherapi` reads a YAML config file that is either:
- a top-level list of database entries, or
- an object with `databases:`.

Example:

```yaml
- name: weatherdb
  driver: postgres
  params:
    uri: postgres://weatherdb:5432/weatherdb?sslmode=disable
    username: weatherdb
    password: weatherdb
```

## Endpoints

- `GET /conditions/current`
- `GET /observations?count=<1..100>&units=<us|metric>`
- `GET /forecast?timestamp=<RFC3339 timestamp>`
- `GET /alerts/current`

Default unit behavior:
- `/conditions/current`: US units
- `/observations`: metric units
- `/forecast`: US units

`/conditions/current`, `/observations`, and `/forecast` support `?units=us|metric`.
`/observations` defaults to `count=5` and validates `count` strictly in range `1..100`.

## Run

```bash
go run ./cmd/weatherapi -config ./config.yml -addr :8080
```
