oxarchive 1.2.0

# oxarchive

Official Rust SDK for [0xArchive](https://0xarchive.io) — Historical Market Data API.

Supports multiple exchanges:
- **Hyperliquid** — Perpetuals data from April 2023
- **Hyperliquid HIP-3** — Builder-deployed perpetuals (February 2026+, free tier: km:US500, Build+: all symbols, Pro+: orderbook history)
- **Lighter.xyz** — Perpetuals data (August 2025+ for fills, Jan 2026+ for OB, OI, Funding Rate)

## Installation

Add to your `Cargo.toml`:

```toml
[dependencies]
oxarchive = "1.2"
tokio = { version = "1", features = ["rt-multi-thread", "macros"] }
```

For WebSocket support (real-time streaming, replay, bulk download):

```toml
oxarchive = { version = "1.2", features = ["websocket"] }
```

## Quick Start

```rust
use oxarchive::OxArchive;

#[tokio::main]
async fn main() -> oxarchive::Result<()> {
    let client = OxArchive::new("your-api-key")?;

    // Hyperliquid data
    let ob = client.hyperliquid.orderbook.get("BTC", None).await?;
    println!("Hyperliquid BTC mid price: {:?}", ob.mid_price);

    // Lighter.xyz data
    let lighter_ob = client.lighter.orderbook.get("BTC", None).await?;
    println!("Lighter BTC mid price: {:?}", lighter_ob.mid_price);

    // HIP-3 builder perps (February 2026+)
    let hip3 = client.hyperliquid.hip3.instruments.list().await?;
    let hip3_ob = client.hyperliquid.hip3.orderbook.get("km:US500", None).await?;
    let hip3_funding = client.hyperliquid.hip3.funding.current("xyz:XYZ100").await?;

    // Historical order book snapshots
    use oxarchive::resources::orderbook::OrderBookHistoryParams;
    let history = client.hyperliquid.orderbook.history("ETH", OrderBookHistoryParams {
        start: 1704067200000_i64.into(),
        end: 1704153600000_i64.into(),
        cursor: None,
        limit: Some(100),
        depth: None,
        granularity: None,
    }).await?;

    Ok(())
}
```

## Configuration

```rust
use oxarchive::OxArchive;
use std::time::Duration;

let client = OxArchive::builder("your-api-key")
    .base_url("https://api.0xarchive.io")  // Optional
    .timeout(Duration::from_secs(60))       // Optional (default: 30s)
    .build()?;
```

## REST API Reference

The sections below show which resources are available on each exchange client:

| Resource | `client.hyperliquid` | `client.hyperliquid.hip3` | `client.lighter` |
|----------|---------------------|--------------------------|-------------------|
| `orderbook` | Yes | Yes | Yes |
| `trades` | Yes | Yes | Yes |
| `instruments` | Yes | Yes | Yes |
| `funding` | Yes | Yes | Yes |
| `open_interest` | Yes | Yes | Yes |
| `candles` | Yes | Yes | Yes |
| `liquidations` | Yes | Yes | -- |
| `orders` | Yes | Yes | -- |
| `l4_orderbook` | Yes | Yes | -- |
| `l3_orderbook` | -- | -- | Yes |
| `freshness()` | Yes | Yes | Yes |
| `summary()` | Yes | Yes | Yes |
| `price_history()` | Yes | Yes | Yes |

### Order Book

```rust
use oxarchive::resources::orderbook::{GetOrderBookParams, OrderBookHistoryParams};

// Get current order book
let ob = client.hyperliquid.orderbook.get("BTC", None).await?;
println!("Mid price: {:?}", ob.mid_price);
println!("Best bid: {:?}", ob.bids.first());
println!("Best ask: {:?}", ob.asks.first());

// Get with specific timestamp and depth
let ob = client.hyperliquid.orderbook.get("BTC", Some(GetOrderBookParams {
    timestamp: Some(1704067200000_i64.into()),
    depth: Some(20),
})).await?;

// Get historical snapshots
let history = client.hyperliquid.orderbook.history("BTC", OrderBookHistoryParams {
    start: 1704067200000_i64.into(),
    end: 1704153600000_i64.into(),
    cursor: None,
    limit: Some(1000),
    depth: None,
    granularity: None,
}).await?;
```

#### Orderbook Depth Limits

| Tier | Max Depth |
|------|-----------|
| Free | 20 |
| Build | 50 |
| Pro | 100 |
| Enterprise | Full Depth |

**Note:** Hyperliquid source data only contains 20 levels. Higher limits apply to Lighter.xyz data.

#### Lighter Orderbook Granularity

Lighter.xyz orderbook history supports a `granularity` parameter for different data resolutions:

```rust
use oxarchive::types::LighterGranularity;

let history = client.lighter.orderbook.history("BTC", OrderBookHistoryParams {
    start: 1704067200000_i64.into(),
    end: 1704153600000_i64.into(),
    cursor: None,
    limit: None,
    depth: None,
    granularity: Some(LighterGranularity::TenSeconds),
}).await?;
```

| Granularity | Interval | Tier Required | Credit Multiplier |
|-------------|----------|---------------|-------------------|
| `Checkpoint` | ~60s | Free+ | 1x |
| `ThirtySeconds` | 30s | Build+ | 2x |
| `TenSeconds` | 10s | Build+ | 3x |
| `OneSecond` | 1s | Pro+ | 10x |
| `Tick` | tick-level | Enterprise | 20x |

### Orderbook Reconstruction (Enterprise)

Tick-level orderbook history returns a full **checkpoint** plus **incremental deltas**, allowing you to reconstruct the exact state of the order book at every tick. This is the most granular data available and is ideal for backtesting, market microstructure research, and latency analysis.

```rust
use oxarchive::OxArchive;
use oxarchive::orderbook_reconstructor::OrderBookReconstructor;
use oxarchive::types::ReconstructOptions;

let client = OxArchive::new("your-api-key")?;

// Option 1: One-shot — fetch and reconstruct in one call
let snapshots = client.lighter.orderbook.history_reconstructed(
    "BTC",
    1704067200000_i64,  // start
    1704070800000_i64,  // end
    Some(20),           // depth (top 20 levels per side)
    true,               // emit_all: snapshot after every tick
).await?;

for snapshot in &snapshots {
    println!("{}: mid={:?}, spread={:?}bps, seq={:?}",
        snapshot.timestamp, snapshot.mid_price, snapshot.spread_bps, snapshot.sequence);
}

// Option 2: Auto-paginated — fetches all pages automatically
let all_snapshots = client.lighter.orderbook.collect_tick_history(
    "BTC",
    1704067200000_i64,
    1704153600000_i64,
    Some(20),
).await?;
println!("{} tick-level snapshots", all_snapshots.len());

// Option 3: Manual control — fetch raw tick data and reconstruct yourself
let tick_data = client.lighter.orderbook.history_tick(
    "BTC", 1704067200000_i64, 1704070800000_i64, None,
).await?;

// Check data integrity
let gaps = OrderBookReconstructor::detect_gaps(&tick_data.deltas);
if !gaps.is_empty() {
    eprintln!("Sequence gaps detected: {:?}", gaps);
}

// Reconstruct with full control
let mut reconstructor = OrderBookReconstructor::new();
reconstructor.initialize(&tick_data.checkpoint);

for delta in &tick_data.deltas {
    reconstructor.apply_delta(delta);
    let snapshot = reconstructor.get_snapshot(Some(10));
    // Process each snapshot...
}

// Or get just the final state (most efficient)
let final_state = reconstructor.reconstruct_final(
    &tick_data.checkpoint, &tick_data.deltas, Some(20),
);
println!("Final mid price: {:?}", final_state.mid_price);
```

#### Manual Pagination

For large time ranges where memory is a concern, paginate manually instead of using `collect_tick_history`:

```rust
let mut cursor = 1704067200000_i64;
let end = 1704153600000_i64;

while cursor < end {
    let tick_data = client.lighter.orderbook.history_tick(
        "BTC", cursor, end, Some(20),
    ).await?;

    if tick_data.deltas.is_empty() {
        break;
    }

    // Process this page...
    let mut reconstructor = OrderBookReconstructor::new();
    let final_state = reconstructor.reconstruct_final(
        &tick_data.checkpoint, &tick_data.deltas, Some(20),
    );
    println!("{}: {} bids, {} asks", final_state.timestamp, final_state.bids.len(), final_state.asks.len());

    // Advance cursor past the last delta
    let last_ts = tick_data.deltas.iter().map(|d| d.timestamp).max().unwrap();
    cursor = last_ts + 1;

    // Fewer than ~1000 deltas means end of range
    if tick_data.deltas.len() < 1000 {
        break;
    }
}
```

### Trades

Cursor-based pagination for efficient retrieval of large datasets.

```rust
use oxarchive::resources::trades::GetTradesParams;

// Get trades with pagination
let result = client.hyperliquid.trades.list("BTC", GetTradesParams {
    start: 1704067200000_i64.into(),
    end: 1704153600000_i64.into(),
    limit: Some(1000),
    cursor: None,
    side: None,
}).await?;

// Paginate through all results
let mut all_trades = result.data;
let mut cursor = result.next_cursor;
while let Some(c) = cursor {
    let page = client.hyperliquid.trades.list("BTC", GetTradesParams {
        start: 1704067200000_i64.into(),
        end: 1704153600000_i64.into(),
        limit: Some(1000),
        cursor: Some(c),
        side: None,
    }).await?;
    all_trades.extend(page.data);
    cursor = page.next_cursor;
}

// Get recent trades (Lighter and HIP-3 only)
let recent = client.lighter.trades.recent("BTC", Some(100)).await?;
let hip3_recent = client.hyperliquid.hip3.trades.recent("km:US500", Some(50)).await?;
```

**Note:** The `recent()` method is available for Lighter.xyz and HIP-3 only. Hyperliquid does not have a recent trades endpoint — use `list()` with a time range instead.

### Instruments

```rust
// List all Hyperliquid instruments
let instruments = client.hyperliquid.instruments.list().await?;
for inst in &instruments {
    println!("{}: {}x leverage", inst.name, inst.max_leverage.unwrap_or(0));
}

// Get specific instrument
let btc = client.hyperliquid.instruments.get("BTC").await?;

// Lighter.xyz instruments (different schema with fees, market IDs)
let lighter_instruments = client.lighter.instruments.list().await?;
for inst in &lighter_instruments {
    println!("{}: taker_fee={:?}, maker_fee={:?}", inst.symbol, inst.taker_fee, inst.maker_fee);
}

// HIP-3 instruments (derived from live data, includes mark price + OI)
let hip3_instruments = client.hyperliquid.hip3.instruments.list().await?;
for inst in &hip3_instruments {
    println!("{} ({}:{}): mark={:?}", inst.coin, inst.namespace, inst.ticker, inst.mark_price);
}
```

### Funding Rates

let current = client.hyperliquid.funding.current("BTC").await?;
println!("Funding rate: {}", current.funding_rate);

// Get history with aggregation interval
let history = client.hyperliquid.funding.history("ETH", FundingHistoryParams {
    start: 1704067200000_i64.into(),
    end: 1704153600000_i64.into(),
    cursor: None,
    limit: None,
    interval: Some(OiFundingInterval::OneHour),
}).await?;
```

#### Aggregation Intervals

| Interval | Description |
|----------|-------------|
| `5m` | 5 minutes |
| `15m` | 15 minutes |

## Web3 Authentication

Wallet-based authentication using SIWE (Sign-In with Ethereum) and x402 USDC payments.

```rust
// Step 1: Get a SIWE challenge
let challenge = client.web3.challenge("0xYourWalletAddress").await?;

// Step 2: Sign the challenge and register
let result = client.web3.signup(
    &challenge.message,
    "0xYourSignature",
).await?;
println!("API Key: {}", result.api_key);

// Manage API keys (requires fresh SIWE signature)
let keys = client.web3.list_keys(&challenge.message, "0xSignature").await?;
client.web3.revoke_key(&challenge.message, "0xSignature", "key-id").await?;

// Subscribe with x402 USDC payment
let sub = client.web3.subscribe("build", "base64_payment_payload").await?;
```

## WebSocket Client

Requires the `websocket` feature. Supports two modes on a single connection:
- **Real-time** — subscribe to live market data
- **Replay** — replay historical data with timing preserved

For bulk data downloads, use the S3 Parquet bulk export via the [Data Explorer](https://0xarchive.io/data).

### Real-time Streaming

```rust
use oxarchive::ws::{OxArchiveWs, ServerMsg, WsOptions};

let mut ws = OxArchiveWs::new(WsOptions::new("your-api-key"));
ws.connect().await?;

ws.subscribe("orderbook", Some("BTC")).await?;
ws.subscribe("trades", Some("ETH")).await?;

let mut rx = ws.rx.take().expect("receiver");
while let Some(msg) = rx.recv().await {
    match msg {
        ServerMsg::Data { channel, coin, data } => {
            println!("{channel} {} update: {}", coin.unwrap_or_default(), data);
        }
        ServerMsg::Error { message } => eprintln!("Error: {message}"),
        _ => {}
    }
}
```

### Historical Replay

```rust
// Replay BTC orderbook at 100x speed
ws.replay("orderbook", "BTC", 1704067200000, Some(1704070800000), Some(100.0)).await?;

// Control playback
ws.replay_pause().await?;
ws.replay_resume().await?;
ws.replay_seek(1704069000000).await?;
ws.replay_stop().await?;
```

## Timestamp Formats

All time parameters accept the `Timestamp` enum:

```rust
use oxarchive::types::Timestamp;

// Unix milliseconds (i64)
let ts: Timestamp = 1704067200000_i64.into();

// ISO 8601 string
let ts: Timestamp = "2024-01-01T00:00:00Z".into();

// chrono::DateTime<Utc>
let ts: Timestamp = chrono::Utc::now().into();
```

## Error Handling

```rust
use oxarchive::Error;

match client.hyperliquid.orderbook.get("BTC", None).await {
    Ok(ob) => println!("Mid price: {:?}", ob.mid_price),
    Err(Error::Api { message, code, .. }) => {
        eprintln!("API error ({code}): {message}");
    }
    Err(Error::Timeout) => eprintln!("Request timed out"),
    Err(Error::Http(e)) => eprintln!("HTTP error: {e}"),
    Err(e) => eprintln!("Other error: {e}"),
}
```

## Examples

Run the included examples:

```bash
export OXARCHIVE_API_KEY="your-api-key"

# Basic usage
cargo run --example basic

# Cursor-based pagination
cargo run --example pagination

# WebSocket (requires websocket feature)
cargo run --example websocket --features websocket
```

## Bulk Data Downloads

For large-scale data exports (full order books, complete trade history, etc.), use the S3 Parquet bulk export available at [0xarchive.io/data](https://0xarchive.io/data). The Data Explorer lets you select time ranges, symbols, and data types, then download compressed Parquet files directly.
