The SteamSets API gives you the same data that powers [steamsets.com](https://steamsets.com): Steam profiles, badge collections, leaderboards, trading card owners, and the live activity feed. Every endpoint takes a JSON body and returns JSON, so any HTTP client works.

**[Quickstart](/quickstart)**

Get an API key and send your first request.

**[API reference](/reference)**

Every public endpoint, with schemas and a Try it panel.

**[Authentication](/authentication)**

Send your API key as a bearer token.

**[TypeScript SDK](/sdk)**

Call the API with typed requests and responses.

## How requests look

All endpoints live under `https://api.steamsets.com/v1`. Each endpoint name has the form `<resource>.<action>`, for example `account.getInfo` or `leaderboard.getAccountLeaderboard`. Most endpoints use `POST` with a JSON body, also when they only read data, so that complex filters do not need to fit in a query string.

```bash
curl https://api.steamsets.com/v1/account.getInfo \
  -H "Authorization: Bearer $STEAMSETS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"id": {"steamId64": "76561199176433616"}}'
```

## What you can build

- Profile widgets that show a Steam level, badge count, and leaderboard rank.
- Badge trackers that compare collections between up to 10 accounts.
- Bots that post leaderboard changes or live site activity to a Discord server.
- Market tools that find which accounts own a trading card or booster pack.
