# Got Cosy: full reference

This is the detailed companion to [llms.txt](https://gotcosy.com/llms.txt). Read llms.txt first
for the short version; this file gives endpoint parameters, response shapes, worked examples and
the scoring model, for an agent that wants to query the data directly rather than crawl pages.

## What Got Cosy is

Got Cosy reads a hotel's own guest reviews and photos and returns one score, 0 to 10, for how
cosy the place feels: warmth, intimacy and character, not luxury or star rating. 17,727 hotels
have been analysed from 68,269 guest reviews across 164 cities. A hotel is only published on the
site once it clears a floor of 5.0; below that it is withheld, not shown with a visible low score.
Around 6,000 hotels currently clear the floor. Nothing in the dataset has ever scored above 7.8;
that ceiling is treated as a feature of the method, not a limitation to apologise for.

The score is not editable by the hotel. It moves only when guests write differently about the
place in future reviews; nothing a hotel buys, submits or asks for changes it.

## Endpoints

All three endpoints are public, read-only, require no API key, and are cached for one hour
(`Cache-Control: public, s-maxage=3600`). None returns email addresses or any personal data.

### GET /api/graph/hotels

List published, cosy-scored hotels.

Query parameters (all optional):

| Parameter | Type | Notes |
|---|---|---|
| `city` | string | Case-insensitive, accent-insensitive substring match, e.g. `Paris` |
| `country` | string | Same matching as `city`, e.g. `France` |
| `min_score` | number | Minimum cosy score 0-10; the 5.0 public floor always applies regardless |
| `limit` | number | Default 20, maximum 100 |
| `offset` | number | Default 0, for pagination |

Response:

```json
{
  "hotels": [
    {
      "slug": "example-hotel-paris",
      "name": "Example Hotel",
      "city": "Paris",
      "country": "France",
      "cosy_score": 7.2,
      "url": "https://gotcosy.com/en/hotels/example-hotel-paris",
      "verified_booking": "stay22",
      "website": "https://example-hotel-paris.example"
    }
  ],
  "total": 143,
  "limit": 20,
  "offset": 0,
  "max_limit": 100
}
```

`verified_booking` is `"own_website"` when a real-browser sweep has verified that the usual
booking link actually lands on the wrong property, and the hotel has its own real (non-OTA)
website to use instead; otherwise it is `"stay22"`, the default. `website` is present only when
the stored URL is a genuine hotel-owned domain (never an OTA, social network or aggregator).

### GET /api/graph/hotel/{slug}

One hotel's full detail. `{slug}` is the value returned by the list endpoint, or the last path
segment of a `gotcosy.com/en/hotels/{slug}` URL.

Published hotel (score 5.0+):

```json
{
  "slug": "example-hotel-paris",
  "name": "Example Hotel",
  "city": "Paris",
  "country": "France",
  "cosy_score": 7.2,
  "description": "A one-sentence, review-grounded description of why the hotel reads as cosy.",
  "signals": ["fireplace", "hands-on host", "exposed beams"],
  "url": "https://gotcosy.com/en/hotels/example-hotel-paris",
  "verified_booking": "stay22"
}
```

Below-floor hotel (score under 5.0, or unrated):

```json
{
  "slug": "example-hotel-below-bar",
  "below_bar": true,
  "note": "does not clear our cosiness bar",
  "city": "Somewhere",
  "country": "Country",
  "url": "https://gotcosy.com/en/hotels/example-hotel-below-bar"
}
```

No score, description or signals are exposed for a below-floor hotel; this matches exactly what
the hotel's own page on gotcosy.com shows. A delisted or unknown slug returns HTTP 404.

### POST /api/mcp

An MCP server (JSON-RPC 2.0 over the MCP Streamable HTTP transport) wrapping the two endpoints
above as tools, for any MCP-capable agent or client. See [mcp.json](https://gotcosy.com/mcp.json)
for the machine-readable connection descriptor.

Tools:

- `find_cosy_hotels(city?, country?, min_score?, limit?)`: same filters as `/api/graph/hotels`,
  returns the same JSON shape as a tool result.
- `get_hotel_feeling(slug)`: same as `/api/graph/hotel/{slug}`.

Example request (initialize is optional in this stateless deployment; a client may call
`tools/list` or `tools/call` directly):

```json
{"jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": {"name": "find_cosy_hotels", "arguments": {"city": "Kyoto", "min_score": 7}}}
```
