### `get_cheapest_venue`

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

Description, as the server wrote it:

```untrusted-server-text
Venues ranked by measured all-in cost (taker fee + half-spread + price impact) of a perp market buy at the base fee tier, from the newest stored 6-hour order-book sweep. Rows that cannot fill or have unconfirmed depth are listed apart, with the reason.
```

### `get_funding`

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

Description, as the server wrote it:

```untrusted-server-text
Current perpetual funding rate of one asset on each venue that lists it, normalized to a 1-hour rate, with the venue interval, open interest and price. Rates are fractions: 0.0001 is 0.01%.
```

### `get_venue_access`

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

Description, as the server wrote it:

```untrusted-server-text
For one jurisdiction, what each venue and the local regulator publish about perp access: yes, restricted, unclear or no, with the basis and the sources a person opened. Not legal advice.
```

### `get_venue_fees`

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

Description, as the server wrote it:

```untrusted-server-text
Base maker and taker rates, the volume fee ladder, leverage and funding terms of one perp venue, each with its source and check date, plus the measured all-in cost of BTC and ETH market buys.
```

### `get_volume_ranking`

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

Description, as the server wrote it:

```untrusted-server-text
CEX and DEX perpetual venues ranked by reported volume and by adjusted volume. Adjusted is the reported figure with held-out venues removed; each hold-out has a dated reason. Measurements, not accusations.
```
