## Rate Limiting

### Three Types of Rate Limits

1. **Application Rate Limit** - Per API key, per region
   - Development keys: 20 requests/second, 100 requests/2 minutes
   - Production keys: Higher limits based on approval

2. **Method Rate Limit** - Per endpoint, per key, per region
   - Each endpoint has its own limit (e.g., match history may be more restricted)

3. **Service Rate Limit** - Per service, shared across all applications
   - Can cause 429 errors without `X-Rate-Limit-Type` header

### Rate Limit Headers

| Header                      | Description                              |
| --------------------------- | ---------------------------------------- |
| `X-App-Rate-Limit`          | Your app's rate limit                    |
| `X-App-Rate-Limit-Count`    | Current count against app limit          |
| `X-Method-Rate-Limit`       | Endpoint's rate limit                    |
| `X-Method-Rate-Limit-Count` | Current count against method limit       |
| `Retry-After`               | Seconds to wait before retrying (on 429) |

### Error Handling

| Code  | Meaning                             | Action                                            |
| ----- | ----------------------------------- | ------------------------------------------------- |
| `429` | Rate limit exceeded                 | Wait for `Retry-After` seconds                    |
| `403` | Forbidden (invalid/blacklisted key) | Check API key validity                            |
| `404` | Not found                           | Resource doesn't exist (e.g., player not in game) |

**Blacklisting:** Repeated violations result in temporary blacklisting (escalating duration), eventually permanent.

## PUUID and Riot ID

### Identifier Types

| ID Type         | Scope             | Use Case                             |
| --------------- | ----------------- | ------------------------------------ |
| **PUUID**       | Global, permanent | Preferred for all lookups            |
| **Summoner ID** | Per-region        | Legacy, still used in some endpoints |
| **Account ID**  | Per-region        | Legacy                               |
| **Riot ID**     | Global            | Display name (gameName#tagLine)      |

### Recommended Workflow

1. Get PUUID from Riot ID:

   ```text
   GET /riot/account/v1/accounts/by-riot-id/{gameName}/{tagLine}
   ```

2. Use PUUID for all subsequent calls:

   ```text
   GET /lol/match/v5/matches/by-puuid/{puuid}/ids
   GET /lol/summoner/v4/summoners/by-puuid/{puuid}
   ```

**Note:** PUUIDs are encrypted per project. A PUUID from your dev key won't work with your production key.

## Twisted Library Usage

This project uses the `twisted` npm package for Riot API calls.

### Installation

```bash
bun add twisted
```

### Basic Setup

```typescript
import { LolApi, RiotApi, TftApi } from "twisted";

const riotApi = new RiotApi({ key: process.env.RIOT_API_KEY });
const lolApi = new LolApi({ key: process.env.RIOT_API_KEY });
```

### Common Operations

```typescript
// Get PUUID from Riot ID
const account = await riotApi.Account.getByRiotId(
  gameName,
  tagLine,
  RegionGroups.AMERICAS,
);

// Get summoner by PUUID
const summoner = await lolApi.Summoner.getByPUUID(puuid, Regions.AMERICA_NORTH);

// Get match history
const matches = await lolApi.Match.list(puuid, RegionGroups.AMERICAS, {
  count: 20,
});

// Get match details
const match = await lolApi.Match.get(matchId, RegionGroups.AMERICAS);

// Get ranked data
const leagues = await lolApi.League.bySummoner(
  summonerId,
  Regions.AMERICA_NORTH,
);
```

### Configuration Options

```typescript
const api = new LolApi({
  key: "RGAPI-xxx",
  rateLimitRetry: true, // Auto-retry on 429 (default: true)
  rateLimitRetryAttempts: 3, // Max retries
  concurrency: 10, // Max concurrent requests
  debug: {
    logTime: true,
    logUrls: true,
    logRatelimits: true,
  },
});
```
