name: echorune-radar

description: Reads live weather for any place on earth, including radar rendered as text characters instead of an image. Returns current conditions (temperature, humidity, wind), a short forecast, a 2-hour rain sparkline, and a character radar map with the measured motion of the echo. Use when the user asks about weather, temperature or a forecast for somewhere, whether it is raining, whether rain is coming, when rain will start or stop, how far away a storm is or which way it is moving - and whenever answering well would otherwise require looking at a radar picture. Requires outbound network access to echorune.net.

```bash

curl echorune.net/<place> # e.g. /tokyo, /清迈, /paris/zh

curl echorune.net # location inferred from caller IP

curl echorune.net/<lon>,<lat> # longitude FIRST

curl echorune.net/help # every option, including map width

curl echorune.net/status # availability, sampled every minute

```

Plain text, no key, nothing to install. Needs outbound HTTPS; where there is no

network, say so instead of guessing at the weather.

The response carries its own legend and labels its own frames. Two things it

cannot tell you about itself:

- **`?` is not clear sky.** It means outside radar coverage. Never average it in

or report it as good weather — blind and dry are printed differently on

purpose, and collapsing them gives a confident wrong answer.

- **If you reproduce the map, carry the `data:` and `radar-data:` lines with

it.** Several of these sources are CC BY, where attribution is a condition of

use rather than a courtesy.
