# autopricer.tf Public REST API

**Last updated:** 2026-08-29

**AI index:** https://autopricer.tf/llms.txt

autopricer.tf is a Team Fortress 2 item pricing service. This page documents the **public, read-only REST API**. There is no API key. These endpoints do not create, update, or delete database records.

If an AI agent is reading this because a user mentioned autopricer.tf: the public documentation lives at `https://autopricer.tf/docs` (HTML) and `https://autopricer.tf/docs.md` (Markdown). Machine-readable OpenAPI is at `https://autopricer.tf/openapi.json`. A short index is at `https://autopricer.tf/llms.txt`.

## Base URL

```
https://autopricer.tf
```

All public endpoints are under `/api` and use JSON.

## Scope

Documented here:

| Method | Path | Purpose |
|---|---|---|
| GET | `/api` | Discovery document (links + endpoint index) |
| GET | `/api/health` | Liveness |
| GET | `/api/items/count` | Total tracked items |
| GET | `/api/items/{page}` | Paginated item catalog |
| GET | `/api/images` | Recent item image URLs |

Not documented (and not part of the public REST API):

- Routes under `/api/dashboard/*` — they exist only to render the website dashboard.
- Any endpoint that writes to the database.

## Conventions

- **No authentication.**
- **Content-Type:** `application/json` (except this documentation).
- **Prices** are in Mann Co. Supply Crate Keys unless a field is explicitly refined metal (`metal`, `raw_*_ref`).
- **Item price fields** (`price`, `buyOrder`, `sellOrder`, `stablePrice`, rolling history, and `raw_*`) serialize as **JSON strings** with up to 4 decimal places, or `null`.
- **Listing price fields** (`keys`, `metal`) serialize as **JSON numbers**, or `null`.
- Boolean query flags (`raw`, `listings`) accept `true`, `1`, `yes`, or `on` (case-insensitive). They may be passed as query parameters.
- Successful payloads include `"success": true`. Errors include `"success": false` and `"error": "<message>"`.
- **Rate limit:** 300 requests per minute per IP. Exceeding it returns HTTP 429.

### Rate-limit error

```http
HTTP/1.1 429 Too Many Requests
```

```json
{
  "success": false,
  "error": "Too many requests — please slow down."
}
```

### Generic error envelope

```json
{
  "success": false,
  "error": "Invalid page"
}
```

| HTTP status | Meaning |
|---|---|
| 400 | Invalid request parameter |
| 404 | Unknown route |
| 429 | Rate limit exceeded |
| 500 | Internal error |
| 503 | Service unavailable (`/api/health` when the live listing feed is down) |

## GET /api

Discovery document for humans and agents. Use this if you only know the host name.

**Example**

```
curl https://autopricer.tf/api
```

**Example response**

```json

    },
    {
      "method": "GET",
      "path": "/api/health",
      "description": "Liveness check"
    },
    {
      "method": "GET",
      "path": "/api/items/count",
      "description": "Total tracked item count"
    },
    {
      "method": "GET",
      "path": "/api/items/{page}",
      "description": "Paginated item catalog, 1000 items per page"
    },
    {
      "method": "GET",
      "path": "/api/images",
      "description": "Up to 500 recent item image URLs"
    }
  ]
}
```

## GET /api/health

Liveness check. Returns HTTP 200 when the service is serving prices and the live listing feed is connected. Returns HTTP 503 when the live feed is disconnected.

**Example**

```
curl -i https://autopricer.tf/api/health
```

**Example response (online)**

```json
{
  "success": true,
  "status": "Online"
}
```

**Example response (offline)**

```http
HTTP/1.1 503 Service Unavailable
```

```json
{
  "success": false,
  "status": "Offline — WS disconnected"
}
```

## GET /api/items/count

Returns how many items are currently tracked.

**Example**

```
curl https://autopricer.tf/api/items/count
```

**Example response**

```json
{
  "success": true,
  "count": 86546
}
```

Use `count` with the 1000-item page size to know how many pages to fetch: `ceil(count / 1000)`.

## GET /api/items/{page}

Paginated catalog of tracked items, ordered by `createdAt` ascending. **Page numbers start at 1.** Each page contains at most **1000** items. Pages past the end return `"success": true` with an empty `items` array.

### Path parameters

| Name | Type | Description |
|---|---|---|
| `page` | integer ≥ 1 | Page number. Invalid values return HTTP 400. |

### Query parameters

| Name | Default | Description |
|---|---|---|
| `raw` | false | When true, add `raw_price_key`, `raw_price_ref`, `raw_buy_key`, `raw_buy_ref`, `raw_sell_key`, `raw_sell_ref` |
| `listings` | false | When true, attach the latest buy/sell listing snapshot for each item |

`listings=true` on a full page of 1000 items is heavier than the default payload. Prefer it only when you need classified listing rows.

**Example — catalog page**

```
curl "https://autopricer.tf/api/items/1"
```

**Example — with raw key/ref breakdown and listings**

```
curl "https://autopricer.tf/api/items/1?raw=true&listings=true"
```

**Example response (one item, default fields)**

```json
{
  "success": true,
  "items": [
    {
      "name": "Strange Ullapool Caber",
      "sku": "307;11",
      "imageUrl": "https://steamcdn-a.akamaihd.net/apps/440/icons/c_caber.2d51e5d213398672527771b1fb88e337442ad695.png",

      "sellOrder": "13.3327",
      "stableBuyOrderPrice": "13.4232",
      "stableSellOrderPrice": "12.8989",
      "verified": false,
      "accurate": true,
      "suspicious": false,
      "stn": false,
      "new": false,
      "type": "free",
      "updatedAt": "1721400000000",

      "price1dAgo": "13.3994",
      "price7dAgo": "13.5716",
      "price30dAgo": "12.6234"
    }
  ]
}
```

`items` in a real response contains up to 1000 objects. The example shows a single item.

**Example response (invalid page)**

```http
HTTP/1.1 400 Bad Request
```

```json
{
  "success": false,
  "error": "Invalid page"
}
```

**Example extra fields when `raw=true`**

```json
{
  "raw_price_key": "13",
  "raw_price_ref": "15.51",
  "raw_buy_key": "12",
  "raw_buy_ref": "54",
  "raw_sell_key": "13",
  "raw_sell_ref": "21.33"
}
```

`raw_*_key` is the whole-keys component. `raw_*_ref` is the leftover refined metal.

**Example extra field when `listings=true`**

Listing identifiers and trade URLs below are placeholders, not live accounts.

```json
{
  "listings": {
    "observed_at": "2026-08-27T22:56:38.058Z",
    "buy": [
      {
        "steamid": "76561198000000000",
        "keys": 12,
        "metal": 52.77,
        "is_bot": true,
        "bumped_at": 1787870425,
        "source": "bptf",
        "channel": "request",
        "trade_url": "https://steamcommunity.com/tradeoffer/new/?partner=123456789&token=EXAMPLE",
        "details": "Buying for 12 keys 52.77 ref",
        "stock_text": null,
        "stock_level": null,
        "stock_limit": null,
        "observed_at": "2026-08-27T22:56:38.058Z"
      }
    ],
    "sell": [
      {
        "steamid": "76561198000000001",
        "keys": 13,
        "metal": 28.33,
        "is_bot": true,
        "bumped_at": 1787871236,
        "source": "bptf",
        "channel": "request",
        "trade_url": "https://steamcommunity.com/tradeoffer/new/?partner=123456790&token=EXAMPLE",
        "details": "Selling for 13 keys 28.33 ref",
        "stock_text": "STOCK = 1",
        "stock_level": 1,
        "stock_limit": null,
        "observed_at": "2026-08-27T22:56:38.058Z"
      }
    ]
  }
}
```

Buy listings are sorted highest price first. Sell listings are sorted lowest price first. If an item has no listing snapshot, `listings` is `{ "observed_at": null, "buy": [], "sell": [] }`.

## GET /api/images

Returns up to **500** items that have a cached image URL, most recently updated first.

**Example**

```
curl https://autopricer.tf/api/images
```

**Example response**

```json
{
  "success": true,
  "images": [
    {
      "name": "Jellyfish Jam Throttlehead",
      "imageUrl": "https://steamcdn-a.akamaihd.net/apps/440/icons/sum22_throttlehead.ccf997318471e47b40a4e8c3396a5aea48a8a884.png"
    }
  ]
}
```

## Fetching the full catalog

1. `GET /api/items/count` → `count`
2. For `page` from 1 to `ceil(count / 1000)`: `GET /api/items/{page}`
3. Optional: add `?raw=true` and/or `?listings=true`
4. Stay under 300 requests per minute per IP

There is no public single-item lookup in this REST API. Filter the paginated catalog by `name` or `sku` on the client.
