# 0xArchive - Replayable Market Data API

## What is 0xArchive?
0xArchive provides historical and replayable market data across two venue APIs: Hyperliquid and Lighter.xyz. HIP-3 builder perps live under the Hyperliquid namespace (`/v1/hyperliquid/hip3`), not a third peer venue API. HIP-4 outcome markets (binary, fully-collateralized prediction markets) live under `/v1/hyperliquid/hip4` and follow the same nested-namespace pattern. We offer REST API, WebSocket streaming, SDKs, CLI, MCP, and Claude Code access to venue data, checkpoint history, Pro order-level routes, data-quality monitoring, and wallet-first auth flows.

## API Overview
- Base URL: `https://api.0xarchive.io`
- Authentication: API key via `X-API-Key` header
- Wallet-first flows: `POST /v1/auth/web3/challenge` and `/v1/web3/*`
- Health: `GET /health` (unauthenticated liveness check)
- Monitoring: `/v1/data-quality/*`
- Response format: JSON with `success`, `data`, and `meta.request_id`
- Rate limits: 15-150 requests/second depending on plan (3-20 concurrent queries per key)
- Legacy compatibility routes: `/v1/*`

## HIP-4 Outcome Markets Endpoints (/v1/hyperliquid/hip4)
HIP-4 caveats for LLMs:
- HIP-4 coins are referenced by their numeric id (e.g. `0`, `1`, `10`, `11`) in REST paths (e.g. `/v1/hyperliquid/hip4/orderbook/0`). The `#`-prefixed form (`#0`, `#10`) is also accepted for callers integrating from on-chain SDKs.
- HIP-4 has no funding, no liquidations, no candles. Those routes return 404 by design. Do not suggest them.
- HIP-4 `mark_price` is an implied probability (0..1), not a USD price. Same field name as perps because Hyperliquid upstream uses `markPx` for both.
- HIP-4 markets settle (often within 1 day). After settlement `is_settled` flips true; historical data stays queryable.
- All notional values are denominated in USDH (Hyperliquid stablecoin).

- GET /v1/hyperliquid/hip4/outcomes - List outcome markets (filter `?is_settled=true|false`, cursor pagination)
- GET /v1/hyperliquid/hip4/outcomes/{outcome_id} - Single outcome detail (includes `aggregated_oi`)
- GET /v1/hyperliquid/hip4/instruments - List all HIP-4 instruments (one row per side; coin id format `10*outcome_id + side`)
- GET /v1/hyperliquid/hip4/instruments/{symbol} - Single instrument details
- GET /v1/hyperliquid/hip4/orderbook/{symbol} - Current order book (Pro+)
- GET /v1/hyperliquid/hip4/orderbook/{symbol}/history - Historical order book (Pro+)
- GET /v1/hyperliquid/hip4/trades/{symbol} - Trade history
- GET /v1/hyperliquid/hip4/trades/{symbol}/recent - Recent trades
- GET /v1/hyperliquid/hip4/openinterest/{symbol} - Side open interest history
- GET /v1/hyperliquid/hip4/openinterest/{symbol}/current - Current side open interest
- GET /v1/hyperliquid/hip4/freshness/{symbol} - Data freshness
- GET /v1/hyperliquid/hip4/summary/{symbol} - Combined market summary
- GET /v1/hyperliquid/hip4/prices/{symbol} - Mid-price history (probability, 0..1)
- GET /v1/hyperliquid/hip4/orders/{symbol}/history - Order history (Pro+)
- GET /v1/hyperliquid/hip4/orders/{symbol}/flow - Order flow aggregation (Pro+)

## Web3 Authentication (Wallet-Based)
No API key required for these endpoints. Use SIWE (Sign-In with Ethereum) to get a free API key programmatically.
- POST /v1/auth/web3/challenge - Get SIWE challenge message (requires: address)
- POST /v1/web3/signup - Create free-tier account and get API key (requires: signed SIWE message)
- POST /v1/web3/keys - List all API keys for wallet (requires: signed SIWE message)
- POST /v1/web3/keys/revoke - Revoke an API key (requires: signed SIWE message + key_id)
- POST /v1/web3/subscribe - Subscribe to a paid tier via x402 USDC payment on Base (requires: tier in body, payment-signature header with EIP-3009 signed transfer)

## Legacy Endpoints (still supported)
- GET /v1/orderbook/{symbol}, /v1/trades/{symbol}, /v1/funding/{symbol}, /v1/openinterest/{symbol}, /v1/instruments

## Data Coverage (Hyperliquid)
- Order Book: April 2023 - Present (snapshot spacing varies by market activity and query window)
- Trades: April 2023 - Present (pre-March 2025 fills are taker-only)
- Candles: March 2025 - Present
- Funding Rates: May 2023 - Present
- Open Interest: May 2023 - Present
- Liquidations: December 2025 - Present
- 220+ perpetual futures contracts

## Data Coverage (Lighter.xyz)
- Trades: August 2025 - Present
- L2 Order Book: January 2026 - Present
- Candles, OI, Funding: August 2025 - Present
- L3 Order Book: March 2026 - Present

## Data Coverage (HIP-3 Builder Perps)
- Order Book, Trades, Candles, OI, Funding, Liquidations: February 2026 - Present
- 125+ markets across 6 builders: xyz (XYZ), flx (Felix Exchange), hyna (HyENA), km (Kinetiq Markets), vntl (Ventuals), cash (dreamcash)

## Data Coverage (HIP-4 Outcome Markets)
- Order Book, Trades, OI, L4 diffs, L4 orders: 2026-05-02 ~07:47 UTC - Present
- No funding, no liquidations, no candles (fully-collateralized binary outcomes, by design)
- Active market count varies as outcomes settle and new ones open. Poll `/v1/hyperliquid/hip4/outcomes` for the live count.

## WebSocket API
- URL: wss://api.0xarchive.io/ws?apiKey=YOUR_API_KEY (also wss://stream.0xarchive.io/ws)
- One connection model for live subscriptions and historical replay
- Real-time streaming (subscribe to live market data)
- Historical replay (replay past data with original timing, configurable speed)
- Realtime + historical replay: orderbook, trades, candles, funding, open_interest, liquidations, plus lighter_* and hip3_* variants (lighter_l3_orderbook, hip3_liquidations) and HIP-4 (hip4_orderbook, hip4_trades, hip4_open_interest)
- Realtime only: ticker, all_tickers, l4_diffs, l4_orders, hip3_l4_diffs, hip3_l4_orders, hip4_l4_diffs, hip4_l4_orders (L4 channels are Pro+)
- liquidations and hip3_liquidations channels are now live: each event is a fill row with `is_liquidation: true`, same wire shape as trades. They also continue to flow on `trades`/`hip3_trades` for backward compatibility — dedupe on `tid` if subscribing to both.
- HIP-4 outcome markets: subscribe with raw `#0` form in the JSON (`{"op":"subscribe","channel":"hip4_orderbook","symbol":"#0"}`). REST routes accept the bare numeric form (`/hip4/orderbook/0`).
- Base WebSocket access requires Build tier or higher

hip4_outcomes = client.hyperliquid.hip4.outcomes.list(is_settled=False)
```

### Rust
```rust
use oxarchive::OxArchive;

let client = OxArchive::new("0xa_your_key")?;
let orderbook = client.hyperliquid().orderbook().get("BTC", None).await?;
