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.

Endpoints Overview

| Endpoint | Method | Cost | Description | |----------|--------|------|-------------| | /v1/portfolio | GET | 1 credit | Portfolio holdings across chains/protocols | | /v1/portfolio/at-block | GET | Add-on + 1 credit | Portfolio valued at a historical block (Ethereum) | | /v1/virtual-users | GET | 1 credit | List virtual users (Pro) | | /v1/virtual-users/portfolio | GET | 1 credit/address | Virtual user holdings (Pro) | | /v1/nav | GET | 1 credit | Net Asset Value — {nav, currency, conversionPrice} | | /v1/wallet | GET | 1 credit | Wallet token balances, excludes DeFi positions | | /v1/transactions | GET | 1 credit | Transaction history with filtering | | /v1/approvals/{chain} | GET | 1 credit | ERC-20 token approval records | | /v1/token-overview | GET | 1 credit | Token breakdown by protocol (PRO only) | | /v1/airdrop | GET | 1 credit | Claimable airdrops (Solana only) | | /v1/historical | GET | 1 credit | Historical portfolio snapshots | | /v1/sync-transactions | POST | 1+ credits | Trigger transaction sync | | /v1/contract-protocol | GET | 5 credits | Resolve contract address to DeFi protocol (refunded on 404) | | /v1/beacon/validators/* | GET | Add-on | ETH validator details, rewards, withdrawals, deposits | | /v1/chains | GET | Free | List supported blockchain networks | | /v1/chains/{chainKey}/protocols | GET | Free | List protocols on a chain | | /v1/status | GET | Free | Check sync status | | /v1/credits | GET | Free | Check credit balance |

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 | | 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

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...', '
