### `get_coin_signal`

- The name "get_coin_signal" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
One coin in full: the overall call, each window running now (5m, 15m, 1h, 4h, 1d) blended across venues with score, up probability, confidence and the move since the window opened, the next windows, each venue's own reading, the daily regime call, the Cryptohopper markets that get its signals and its latest delivery, the live backtest, and the newest headlines that name it. Pass timeframe to narrow it to one window.
```

### `get_history`

- The name "get_history" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The blended reading of one coin's window over the last hours (up to 48), thinned to about 36 rows: time, up probability, score and confidence.
```

### `get_methodology`

- The name "get_methodology" says "get": a word for reading.
- Tag private-data: The description's first sentence says "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
The methodology document: what the score is, confidence, window matching, options readings, the backtest and the daily regime rule. Without a section: the list of sections and the introduction; with one: that section.
```

### `get_news`

- The name "get_news" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
The latest crypto headlines from CoinArticle, newest first, each with the live overall Buy/Sell/Hold call of every tracked coin it names. Pass coin to keep only headlines that name it.
```

### `get_overview`

- The name "get_overview" says "get": a word for reading.
- Tag private-data: The description's first sentence says "table": it reads databases.

Description, as the server wrote it:

```untrusted-server-text
Every tracked coin in one table: spot price, the overall Buy/Sell/Hold call with score and confidence, the 1 hour window, and the daily regime call (long or flat).
```

### `get_regime`

- The name "get_regime" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The daily regime (trend) rule relayed to Cryptohopper: long while the Coinbase daily close is more than one 20-day sigma above its 50-day average, flat once more than one below. Without a coin: the board for every coin; with a coin: its call, distance, days in state and the close that would change it.
```

### `get_results`

- The name "get_results" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
What following the calls would have returned, trading the coin against USD on Coinbase with fees, next to buy and hold: net and gross return, round trips, win rate, drawdown and the current position. Without a coin: one strategy (default: the daily regime) for every coin; with a coin: all eight strategies.
```

### `get_signal_markets`

- The name "get_signal_markets" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Which exchange markets on Cryptohopper receive the daily trend signals (buy when a coin turns long, sell when it turns flat), in each exchange's own market format such as BTCUSDT, XBT/EUR or BTC-USD. Without arguments: every exchange with its coin and market counts; with exchange: its markets per coin; with coin: that coin's markets on every exchange; with both: that one list.
```

### `get_trend_changes`

- The name "get_trend_changes" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The coins whose daily trend (regime) call changed, newest decision first: turned long (sent to Cryptohopper as a buy signal) or turned flat (a sell), decided at 00:05 UTC on the daily close, plus the next decision time, the coins whose live price is closest to the level that would change their call, how many Cryptohopper markets accepted each recent signal, and how many coins were long after each daily close over the last 90 days. A coin's starting call is not listed as a change. Give a coin for that coin alone: its current call, since when, whether it began as a change, and its calls over the last 90 closes.
```

### `list_coins_and_venues`

- The name "list_coins_and_venues" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Which coins have venue readings, the windows, and each venue with its type and how many coins it covers.
```
