This page shows the basic flow for calling the API. You need the public base URL and the API key issued for your account.

## 1) Prepare credentials

| Value      | Description                     |
| ---------- | ------------------------------- |
| `BASE_URL` | `https://api-gw.verolabs.co`    |
| `API_KEY`  | API key issued for your account |

<Info>
  Use `BASE_URL=https://api-gw.verolabs.co` and replace `API_KEY` with your own key.
</Info>

## 2) Send your first request

```bash theme={null}
curl --request GET   --url "https://api-gw.verolabs.co/v1/instruments?limit=5"   --header "X-API-KEY: $API_KEY"
```

A successful response returns JSON:

```json theme={null}
{
  "data": [
    {
      "symbol": "BTCUSDT",
      "asset_class": "crypto",
      "exchange": "BINANCE",
      "status": "active"
    }
  ]
}
```

## 3) Query time-based data

Endpoints with `from` and `to` use ISO 8601 UTC timestamps with a `Z` suffix.

```bash theme={null}
curl --request GET   --url "https://api-gw.verolabs.co/v1/candles?symbol=BTCUSDT&resolution=1m&from=2026-05-15T00:00:00Z&to=2026-05-15T01:00:00Z"   --header "X-API-KEY: $API_KEY"
```

## 4) Use the API playground

Every endpoint under **APIs** includes an interactive playground.

## Key rules

| Rule                     | Note                                      |
| ------------------------ | ----------------------------------------- |
| Use UTC `Z` timestamps   | Example: `2026-05-15T00:00:00Z`           |
| Set a reasonable `limit` | Keeps responses smaller and faster        |
| Use `next_cursor`        | Continue through paginated list responses |
| Do not parse cursors     | Treat cursors as opaque tokens            |
