Virtual Users Portfolio API

Manage and query portfolios for virtual users — abstracted identities that represent balance-tracking or CEX-linked accounts. Virtual user endpoints follow the same patterns as Portfolio but use virtual:<id> addresses.

Pro subscription required. Virtual users are a Pro feature. Create and manage them in the Octav Pro app — the API provides read-only access.

Interactive Playground: Test these endpoints in the API Playground. Get your API key at data.octav.fi

Cost: 1 credit per call (list) · 1 credit per virtual user address (portfolio)

List Virtual Users

Returns all virtual users belonging to the authenticated API user.

Endpoint

GET https://api.octav.fi/v1/virtual-users

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

Parameters

No query parameters required — returns all virtual users for the authenticated user.

Response

Returns an array of virtual user objects.

string

Virtual user identifier in virtual:<id> format. Use this value in the portfolio endpoint’s addresses parameter.

string

The virtual user type (e.g. BALANCE, CEX)

string

User-defined label for the virtual user

Data Freshness

The Virtual Users Portfolio endpoint uses the same caching strategy as Portfolio:

How Caching Works

Cache Duration: 1 minuteWhen data is less than 1 minute old:

Cached data returned immediately
Response time: under 100ms

When data is more than 1 minute old:

Cached data returned immediately
Background sync initiated for next request
Next request gets fresh data

With waitForSync=true:

Waits for sync if data is stale
Returns data less than 1 minute old
Response time: Variable (1-10 seconds)

Best Practices

For most use cases:

Use default waitForSync=false
Data fresher than 1 minute is sufficient
Fast response times

For real-time tracking:

Set waitForSync=true when you need the absolute latest data
Accept longer response times
Consider rate limits

Use Cases

List & Query
Per-User Breakdown
Combined View

Discover virtual users and fetch their portfolios in a single flow:

// Step 1: List all virtual users
const usersResponse = await fetch(
  'https://api.octav.fi/v1/virtual-users',
  { headers: { 'Authorization': `Bearer ${apiKey}` } }
);
const virtualUsers = await usersResponse.json();

// Step 2: Fetch aggregated portfolio for all virtual users
const addresses = virtualUsers.map(u => u.address).join(',');
const portfolioResponse = await fetch(
  `https://api.octav.fi/v1/virtual-users/portfolio?addresses=${addresses}&aggregated=true`,
  { headers: { 'Authorization': `Bearer ${apiKey}` } }
);
const portfolio = await portfolioResponse.json();
console.log(`Total Net Worth: $${portfolio[0].networth}`);

Fetch individual portfolios for each virtual user:

const addresses = virtualUsers.map(u => u.address).join(',');
const response = await fetch(
  `https://api.octav.fi/v1/virtual-users/portfolio?addresses=${addresses}`,
  { headers: { 'Authorization': `Bearer ${apiKey}` } }
);

const portfolios = await response.json();
portfolios.forEach(portfolio => {
  const user = virtualUsers.find(u => u.address === portfolio.address);
  console.log(`${user.label}: $${portfolio.networth}`);
});

Combine virtual user and wallet portfolios for a full picture:

// Fetch wallet portfolio
const walletPortfolio = await fetch(
  `https://api.octav.fi/v1/portfolio?addresses=${walletAddress}`,
  { headers: { 'Authorization': `Bearer ${apiKey}` } }
).then(r => r.json());

// Fetch virtual user portfolio
const virtualPortfolio = await fetch(
  `https://api.octav.fi/v1/virtual-users/portfolio?addresses=${virtualAddress}&aggregated=true`,
  { headers: { 'Authorization': `Bearer ${apiKey}` } }
).then(r => r.json());

const totalNetWorth =
  parseFloat(walletPortfolio[0]?.networth ?? '0') +
  parseFloat(virtualPortfolio[0]?.networth ?? '0');
console.log(`Combined Net Worth: $${totalNetWorth.toFixed(2)}`);

Error Responses

400 Bad Request

Invalid parameters provided.

{
  "error": "Bad Request",
  "message": "addresses parameter is required"
}

Common causes:

Missing addresses parameter (portfolio endpoint)
Invalid address format (must be virtual:<id>)
More than 10 addresses in single request

401 Unauthorized

Authentication failed.

{
  "error": "Unauthorized",
  "message": "Invalid API key"
}

Solution: Check your API key in the Authorization header

403 Forbidden

Attempted to access virtual users that don’t belong to the authenticated API user.

{
  "error": "Forbidden",
  "message": "One or more virtual user addresses do not belong to this account"
}

Solution: Only use virtual user addresses returned by GET /v1/virtual-users for your API key

429 Too Many Requests

Rate limit exceeded.

{
  "error": "Rate limit exceeded",
  "message": "You have exceeded your rate limit",
  "retry_after": 60
}

Solution: Wait for the specified time or implement retry logic

402 Payment Required

Insufficient credits.

{
  "error": "Insufficient credits",
  "message": "Please purchase more credits to continue"
}

Solution: Purchase more credits at data.octav.fi
