## Core Endpoints

### Portfolio

Get holdings across wallets and DeFi protocols.

```javascript
const response = await fetch(
  `https://api.octav.fi/v1/portfolio?addresses=${address}`,
  { headers: { 'Authorization': `Bearer ${apiKey}` } }
);
const portfolio = await response.json();
// portfolio.networth, portfolio.assetByProtocols, portfolio.chains
```

**Parameters:**
- `addresses` (required): Comma-separated EVM/Solana addresses
- `includeNFTs`: Include NFT holdings (default: false)
- `includeImages`: Include asset/protocol image URLs (default: false)
- `waitForSync`: Wait for fresh data if stale (default: false)

**Response structure:**
```json
{
  "address": "0x...",
  "networth": "45231.89",
  "assetByProtocols": {
    "wallet": { "key": "wallet", "name": "Wallet", "value": "12453.20", "assets": [...] },
    "aave_v3": { "key": "aave_v3", "name": "Aave V3", "value": "8934.12", "assets": [...] }
  },

    "ethereum": { "value": "25123.45", "protocols": [...] },
    "arbitrum": { "value": "20108.44", "protocols": [...] }
  }
}
```

### Nav (Net Asset Value)

Get simple net worth number.

```javascript
const response = await fetch(
  `https://api.octav.fi/v1/nav?addresses=${address}`,
  { headers: { 'Authorization': `Bearer ${apiKey}` } }
);
const nav = await response.json(); // Returns: 1235564.43434
```

### Transactions

Query transaction history with filtering.

```javascript
const params = new URLSearchParams({
  addresses: '0x...',
  limit: '50',
  offset: '0',
  sort: 'DESC',
  hideSpam: 'true'
});

const response = await fetch(
  `https://api.octav.fi/v1/transactions?${params}`,
  { headers: { 'Authorization': `Bearer ${apiKey}` } }
);
```

**Required parameters:**
- `addresses`: Wallet address(es)
- `limit`: Results per page (1-250)
- `offset`: Pagination offset

**Optional filters:**
- `sort`: `DESC` (newest) or `ASC` (oldest)
- `networks`: Chain filter (e.g., `ethereum,arbitrum,base`)
- `txTypes`: Transaction type filter (e.g., `SWAP,DEPOSIT`)
- `protocols`: Protocol filter (e.g., `uniswap_v3,aave_v3`)
- `hideSpam`: Exclude spam (default: false)
- `hideDust`: Exclude dust transactions (default: false)
- `startDate`/`endDate`: ISO 8601 date range
- `initialSearchText`: Full-text search in assets

**Response (array of transactions):**
```json
[{
  "hash": "0xa1b2c3...",
  "timestamp": "1699012800",
  "chain": { "key": "ethereum", "name": "Ethereum" },
  "type": "SWAP",
  "protocol": { "key": "uniswap_v3", "name": "Uniswap V3" },
  "fees": "0.002134",
  "feesFiat": "7.12",
  "assetsIn": [{ "symbol": "WETH", "amount": "1.5", "value": "4800.00" }],
  "assetsOut": [{ "symbol": "USDC", "amount": "4795.23", "value": "4795.23" }]
}]
```

### Sync Transactions

Trigger manual sync for fresh transaction data.

```javascript
const response = await fetch('https://api.octav.fi/v1/sync-transactions', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${apiKey}`,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({ addresses: ['0x...'] })
});
// Returns: "Address is syncing" or "Address already syncing"
```

**Cost:** 1 credit + 1 credit per 250 transactions indexed (first-time only).

### Status (Free)

Check sync status before expensive operations.

```javascript
const response = await fetch(
  `https://api.octav.fi/v1/status?addresses=${address}`,
  { headers: { 'Authorization': `Bearer ${apiKey}` } }
);
const [status] = await response.json();
// status.portfolioLastSync, status.transactionsLastSync, status.syncInProgress
```

### Credits (Free)

Check remaining credit balance.

```javascript
const credits = await fetch('https://api.octav.fi/v1/credits', {
  headers: { 'Authorization': `Bearer ${apiKey}` }
}).then(r => r.json());
// Returns: 19033 (number)
```

### Historical Portfolio

Get portfolio snapshot for a specific date. Requires subscription.

```javascript
const response = await fetch(
  `https://api.octav.fi/v1/historical?addresses=${address}&date=2024-11-01`,
  { headers: { 'Authorization': `Bearer ${apiKey}` } }
);
```

### Token Overview (PRO Only)

Detailed token breakdown by protocol.

```javascript
const response = await fetch(
  `https://api.octav.fi/v1/token-overview?addresses=${address}&date=2024-11-01`,
  { headers: { 'Authorization': `Bearer ${apiKey}` } }
);
```

## Transaction Types

Common types for filtering:

| Type | Description |
|------|-------------|
| `TRANSFERIN` | Received tokens |
| `TRANSFEROUT` | Sent tokens |
| `SWAP` | Token exchange |
| `DEPOSIT` | DeFi deposit |
| `WITHDRAW` | DeFi withdrawal |
| `STAKE` | Staking tokens |
| `UNSTAKE` | Unstaking tokens |
| `CLAIM` | Reward claims |
| `ADDLIQUIDITY` | LP deposit |
| `REMOVELIQUIDITY` | LP withdrawal |
| `BORROW` | Lending protocol borrow |
| `LEND` | Lending protocol supply |
| `BRIDGEIN` / `BRIDGEOUT` | Cross-chain bridge |
| `APPROVAL` | Token approval |
| `MINT` | NFT/token minting |

## Supported Chains

**Full support (portfolio + transactions):** ethereum, arbitrum, base, polygon, optimism, avalanche, binance, solana, blast, linea, gnosis, sonic, starknet, fraxtal, unichain

**Portfolio only:** scroll, zksync (era), mantle, manta, fantom, cronos, celo, and 40+ more

Use chain keys in `networks` filter: `?networks=ethereum,arbitrum,base`

## Error Handling

```javascript
async function fetchWithRetry(url, options, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    const response = await fetch(url, options);

    if (response.status === 429) {
      const retryAfter = response.headers.get('Retry-After') || 60;
      await new Promise(r => setTimeout(r, retryAfter * 1000));
      continue;
    }

    if (!response.ok) {
      const error = await response.json();
      throw new Error(`API Error ${response.status}: ${error.message}`);
    }

    return response;
  }
  throw new Error('Max retries exceeded');
}
```

**Common errors:**
- `401`: Invalid/missing API key
- `402`: Insufficient credits
- `403`: Endpoint requires PRO subscription
- `429`: Rate limit exceeded (wait and retry)
- `404`: Address not indexed (>100k transactions)

## Cost Optimization

1. **Batch addresses:** `?addresses=0x123,0x456,0x789` (1 credit vs 3)
2. **Use free endpoints:** `/v1/status` and `/v1/credits` cost nothing
3. **Filter on server:** Use `networks`, `txTypes` params vs client filtering
4. **Cache results:** Portfolio cached 1 minute, transactions 10 minutes
5. **Check status first:** Avoid unnecessary syncs

## Common Patterns

### Multi-wallet portfolio

```javascript
const addresses = ['0x123...', '0x456...', '0x789...'];
const response = await fetch(
  `https://api.octav.fi/v1/portfolio?addresses=${addresses.join(',')}`,
  { headers: { 'Authorization': `Bearer ${apiKey}` } }
);
```

### Paginated transaction fetch

```javascript
async function getAllTransactions(address) {
  const transactions = [];
  let offset = 0;
  const limit = 250;

  while (true) {
    const response = await fetch(
      `https://api.octav.fi/v1/transactions?addresses=${address}&limit=${limit}&offset=${offset}&sort=DESC`,
      { headers: { 'Authorization': `Bearer ${apiKey}` } }
    );
    const batch = await response.json();
    if (batch.length === 0) break;
    transactions.push(...batch);
    offset += batch.length;
    if (batch.length < limit) break;
  }

  return transactions;
}
```

### Smart sync workflow

```javascript
async function smartSync(address) {
  // Check status first (free)
  const [status] = await fetch(
    `https://api.octav.fi/v1/status?addresses=${address}`,
    { headers: { 'Authorization': `Bearer ${apiKey}` } }
  ).then(r => r.json());

  const lastSync = new Date(status.transactionsLastSync);
  const minutesSinceSync = (Date.now() - lastSync) / 1000 / 60;

  if (minutesSinceSync > 10 && !status.syncInProgress) {
    await fetch('https://api.octav.fi/v1/sync-transactions', {
      method: 'POST',
      headers: { 'Authorization': `Bearer ${apiKey}`, 'Content-Type': 'application/json' },
      body: JSON.stringify({ addresses: [address] })
    });
  }
}
```

## TypeScript Interfaces

```typescript
interface Portfolio {
  address: string;
  networth: string;
  cashBalance: string;
  dailyIncome: string;
  dailyExpense: string;
  fees: string;
  feesFiat: string;

  assetByProtocols: Record<string, Protocol>;
  chains: Record<string, Chain>;
}

interface Protocol {
  key: string;
  name: string;
  value: string;
  assets: Asset[];
}

interface Asset {
  balance: string;
  symbol: string;
  price: string;
  value: string;
  contractAddress?: string;
  chain?: string;
}

interface Transaction {
  hash: string;
  timestamp: string;
  chain: { key: string; name: string };
  from: string;
  to: string;
  type: string;
  protocol?: { key: string; name: string };
  value: string;
  valueFiat: string;
  fees: string;
  feesFiat: string;
