Octav API Integration

API for cryptocurrency portfolio tracking, transaction history, and DeFi analytics.

Quick Reference

Base URL: https://api.octav.fi Auth: Bearer token in Authorization header Rate Limit: 360 requests/minute/key Pricing: Credit-based ($0.02-0.025/credit) Dev Portal: https://data.octav.fi

Authentication

curl -X GET "https://api.octav.fi/v1/credits" \
  -H "Authorization: Bearer YOUR_API_KEY"

Store API key in environment variable OCTAV_API_KEY. Never hardcode.

Access methods

Default to the API-key REST API documented below. It covers all 25 endpoints.

Octav also exposes 5 endpoints over the x402 payment protocol at /v1/agent/{portfolio,wallet,nav,status,chains} — 0.025 USDC per call on Base, no API key. Use x402 only when:

• the user explicitly asked for x402 or pay-per-call access, or
• the agent has its own funded wallet and no API key is available.

Otherwise use /v1/* with a Bearer token, and mention x402 exists if one of those cases applies. Do not start from x402 by default.

There is no /v1/agent/transactions — transaction history requires an API key.

Subscribe Snapshot (POST, 1200 credits) enables daily portfolio snapshots for an address, which /v1/historical then reads.

x402 endpoints (no API key — see Access methods above)

Endpoint	Method	Cost	Description
/v1/agent/portfolio	GET	0.025 USDC	Wallet and protocol holdings
/v1/agent/wallet	GET	0.025 USDC	Wallet holdings only
/v1/agent/nav	GET	0.025 USDC	Net Asset Value — {nav, currency, conversionPrice}
/v1/agent/status	GET	0.025 USDC	Sync status
/v1/agent/chains	GET	0.025 USDC	Supported chains

An unpaid request returns HTTP 402 with a base64 payment-required header containing the payment challenge (USDC on Base, eip155:8453). An x402-capable HTTP client settles it and retries automatically.

Core Endpoints

Portfolio

Get holdings across wallets and DeFi protocols.

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): EVM or Solana address. Comma-separate multiple addresses in one request to save credits.
• includeImages: Include asset/protocol image URLs (default: false)
• includeExplorerUrls: Include block explorer URLs (default: false)
• waitForSync: Wait for fresh data if stale (default: false)

Response structure:

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

Nav (Net Asset Value)

Get net worth as a single value, optionally converted to another currency.

const response = await fetch(
  `https://api.octav.fi/v1/nav?addresses=${address}&currency=USD`,
  { headers: { 'Authorization': `Bearer ${apiKey}` } }
);
const { nav, currency, conversionPrice } = await response.json();
// { "nav": 1235564.43, "currency": "USD", "conversionPrice": 1 }

Parameters:

• addresses (required): EVM or Solana address
• currency: Fiat USD (default), EUR, CAD, AED, CHF, SGD; crypto ETH, SOL, cbBTC, EURC, BNB
• waitForSync: Wait for fresh data if stale (default: false)

conversionPrice is the rate used — for fiat, the exchange rate from USD; for crypto, the weighted average USD price across the queried wallets.

Transactions

Query transaction history with filtering.

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, UTC, both inclusive. endDate rounds up to the end of its calendar day (23:59:59Z), so for a single day set both to the same date; never set endDate to the next day's midnight (duplicates the boundary tx)
• interactingAddresses: Filter by interacting addresses (comma-separated)
• tokenId: Filter by NFT token ID
• initialSearchText: Full-text search in assets

Response (array of transactions):

[{
  "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.

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.

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.

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.

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.

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

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

Error Handling

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: comma-separate them in one request — ?addresses=0x123,0x456,0x789 — to save credits versus one call each
2. Use free endpoints: /v1/status, /v1/credits, /v1/chains, and /v1/chains/{chainKey}/protocols 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

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

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

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] })
    });
  }
}
