# NowChess Tournament API
Swiss-system bot tournaments. Bots are paired by score each round; all bots play every round (no eliminations). Game moves flow through the existing board and bot endpoints — the tournament module only orchestrates pairings, standings, and lifecycle.
---
## Base path
```
/api/tournament
```
Routing: `/api/tournament``nowchess-tournament-active:8086`
---
## Authentication
All endpoints require a valid JWT (`Authorization: Bearer <token>`).
Bot-facing streaming endpoints additionally require the token's subject to match the registered `botId`.
---
## Data models
### Tournament
```json
{
"id": "t7kXq2",
"name": "Friday Night Bots",
"status": "created | started | finished",
"rounds": 5,
"currentRound": 2,
"timeControl": {
"limitSeconds": 300,
"incrementSeconds": 3
},
"createdBy": "userId",
"createdAt": "2026-05-13T18:00:00Z",
"startedAt": "2026-05-13T18:05:00Z",
"finishedAt": null
}
```
### Standing
```json
{
"rank": 1,
"botId": "bot_abc",
"botName": "StockfishClone",
"points": 3.5,
"wins": 3,
"draws": 1,
"losses": 0,
"buchholz": 9.0
}
```
Tiebreaker: Buchholz score (sum of opponents' points).
### Pairing
```json
{
"round": 2,
"whiteBot": "bot_abc",
"blackBot": "bot_xyz",
"gameId": "j0nPtcjl",
"result": "white | black | draw | ongoing"
}
```
### TournamentEvent (SSE)
```json
{ "type": "tournamentStarted", "tournamentId": "t7kXq2" }
{ "type": "roundStarted", "tournamentId": "t7kXq2", "round": 2 }
{ "type": "pairingReady", "tournamentId": "t7kXq2", "round": 2, "gameId": "j0nPtcjl", "color": "white" }
{ "type": "roundFinished", "tournamentId": "t7kXq2", "round": 2 }
{ "type": "tournamentFinished","tournamentId": "t7kXq2" }
```
---
## Endpoints
### Tournament lifecycle
#### Create tournament
```
POST /api/tournament
```
Body:
```json
{
"name": "Friday Night Bots",
"rounds": 5,
"timeControl": {
"limitSeconds": 300,
"incrementSeconds": 3
}
}
```
Response `201 Created`:
```json
{ "id": "t7kXq2" }
```
The creator becomes the tournament director. Only the director can start and delete the tournament.
---
#### Get tournament
```
GET /api/tournament/{tournamentId}
```
Response `200 OK`: `Tournament` object.
---
#### List tournaments
```
GET /api/tournament
```
Query params:
| Param | Type | Default |
|----------|---------------------------------|-----------|
| `status` | `created\|started\|finished` | (all) |
| `limit` | integer (max 50) | 20 |
| `offset` | integer | 0 |
Response `200 OK`:
```json
{
"tournaments": [ /* Tournament[] */ ],
"total": 42
}
```
---
#### Start tournament
```
POST /api/tournament/{tournamentId}/start
```
Requires at least 2 registered bots. Computes round 1 pairings (random for round 1; score-based from round 2). Creates one game per pairing via `POST /api/board/game`.
Response `200 OK`: updated `Tournament` object.
---
#### Delete tournament
```
DELETE /api/tournament/{tournamentId}
```
Only allowed while `status == "created"`. Response `204 No Content`.
---
### Bot registration
#### Register bot
```
POST /api/tournament/{tournamentId}/bots
```
Registers a bot for the tournament. Must be called before the tournament starts.
The token subject must match the bot being registered.
Body:
```json
{ "botId": "bot_abc" }
```
Response `200 OK`:
```json
{ "botId": "bot_abc", "tournamentId": "t7kXq2" }
```
---
#### Unregister bot
```
DELETE /api/tournament/{tournamentId}/bots/{botId}
```
Only allowed while `status == "created"`. Response `204 No Content`.
---
#### List registered bots
```
GET /api/tournament/{tournamentId}/bots
```
Response `200 OK`:
```json
{
"bots": [
{ "botId": "bot_abc", "botName": "StockfishClone" }
]
}
```
---
### Standings and pairings
#### Get standings
```
GET /api/tournament/{tournamentId}/standings
```
Response `200 OK`:
```json
{ "standings": [ /* Standing[] */ ] }
```
---
#### Get pairings for a round
```
GET /api/tournament/{tournamentId}/rounds/{round}/pairings
```
Response `200 OK`:
```json
{ "pairings": [ /* Pairing[] */ ] }
```
---
### Bot streaming
#### Stream tournament events
```
GET /api/tournament/{tournamentId}/stream
```
Headers: `Accept: text/event-stream`
Server-Sent Events stream scoped to this tournament. The bot receives `pairingReady` events when it is assigned a game, at which point it should connect to the existing bot game stream:
```
GET /bot/stream/game/{gameId} (existing endpoint)
POST /bot/game/{gameId}/move/{uci} (existing endpoint)
```
The tournament module never sends moves — bots do that themselves through the existing bot endpoints.
---
## Typical bot flow
```
1. POST /api/tournament # director creates tournament
2. POST /api/tournament/{id}/bots # each bot registers
3. POST /api/tournament/{id}/start # director starts
4. GET /api/tournament/{id}/stream (SSE) # each bot opens stream
-- per round --
5. receive: pairingReady { gameId, color }
6. GET /bot/stream/game/{gameId} # existing endpoint
7. POST /bot/game/{gameId}/move/{uci} # existing endpoint, repeated
-- game ends --
8. receive: roundFinished
9. GET /api/tournament/{id}/standings # optional, inspect scores
-- repeat 59 for each round --
10. receive: tournamentFinished
11. GET /api/tournament/{id}/standings # final ranking
```
---
## Error responses
| Status | Meaning |
|--------|------------------------------------------------------|
| 400 | Invalid request body or parameters |
| 401 | Missing or invalid JWT |
| 403 | Action not allowed (wrong director, wrong bot, etc.) |
| 404 | Tournament or bot not found |
| 409 | Tournament already started / bot already registered |

title: NowChess Tournament API
description: |
Swiss-system bot tournaments, modelled after the Lichess API style.
Game moves flow through the existing board and bot endpoints — this module
handles pairings, standings, and lifecycle only.
## Streaming
Endpoints marked **NDJSON** return newline-delimited JSON objects
(`application/x-ndjson`). Each line is one complete JSON object. The
connection stays open until the tournament or round ends.
## Bot flow
```
POST /api/tournament # create
POST /api/tournament/{id}/join # each bot joins
POST /api/tournament/{id}/start # director starts
GET /api/tournament/{id}/stream (NDJSON) # open before start
-- per round --
receive gameStart { gameId, color }
GET /bot/stream/game/{gameId} (existing, NDJSON)
POST /bot/game/{gameId}/move/{uci} (existing)
-- repeat --
GET /api/tournament/{id}/results (NDJSON) # final standings
