Covers orderbooks, trades, candles, funding rates, open interest, liquidations, and data quality. Use when the user asks about crypto market data, orderbooks, trades, funding rates, or historical prices on Hyperliquid, Lighter.xyz, or HIP-3. allowed-tools: Bash argument-hint: "query, e.g. 'BTC funding rate' or 'ETH 4h candles last week'" metadata: {"openclaw":{"requires":{"env":["OXARCHIVE_API_KEY"]},"primaryEnv":"OXARCHIVE_API_KEY"}}

0xArchive API Skill

Query historical and real-time crypto market data from 0xArchive using curl. Three exchanges are supported: Hyperliquid (perps DEX), Lighter.xyz (order-book DEX), and HIP-3 (Hyperliquid builder perps). Data types: orderbooks, trades, candles, funding rates, open interest, liquidations, and data quality metrics.

Authentication

All endpoints require the x-api-key header. The key is read from $OXARCHIVE_API_KEY.

curl -s -H "x-api-key: $OXARCHIVE_API_KEY" "https://api.0xarchive.io/v1/..."

Exchanges & Coin Naming

| Exchange | Path prefix | Coin format | Examples | |----------|-------------|-------------|---------| | Hyperliquid | /v1/hyperliquid | UPPERCASE | BTC, ETH, SOL | | HIP-3 | /v1/hyperliquid/hip3 | Case-sensitive, builder:NAME | km:US500, xyz:GOLD, hyna:BTC, vntl:SPACEX, flx:TSLA, cash:NVDA | | Lighter | /v1/lighter | UPPERCASE | BTC, ETH |

Hyperliquid and Lighter auto-uppercase the symbol server-side. HIP-3 coin names are passed through as-is.

Timestamps

All timestamps are Unix milliseconds. Use these shell helpers:

NOW=$(( $(date +%s) * 1000 ))
HOUR_AGO=$(( NOW - 3600000 ))
DAY_AGO=$(( NOW - 86400000 ))
WEEK_AGO=$(( NOW - 604800000 ))

Response Format

Every response follows this shape:

{
  "success": true,
  "data": [ ... ],
  "meta": {
    "count": 100,
    "request_id": "uuid",
    "next_cursor": "1706000000000"   // present when more pages exist
  }
}

Additional real-time channels available via WebSocket (wss://api.0xarchive.io/ws?apiKey=KEY):

| Channel | Notes | |---------|-------| | l4_diffs | L4 orderbook diffs with user attribution (Build+, real-time only) | | l4_orders | Order lifecycle events with user attribution (Build+, real-time only) | | lighter_l3_orderbook | Lighter L3 order-level orderbook snapshots (Pro+, historical only) | | hip3_liquidations | HIP-3 liquidation events with long/short direction (Build+, historical only) | | hip3_l4_diffs | HIP-3 L4 orderbook diffs (Build+, real-time only) | | hip3_l4_orders | HIP-3 order lifecycle events (Build+, real-time only) |

Web3 Authentication (/v1)

Get API keys programmatically using an Ethereum wallet (SIWE). No API key required for these endpoints.

| Endpoint | Params | Notes | |----------|--------|-------| | POST /auth/web3/challenge | address (wallet address) | Returns SIWE message to sign | | POST /web3/signup | message, signature | Returns free-tier API key | | POST /web3/keys | message, signature | List all keys for wallet | | POST /web3/keys/revoke | message, signature, key_id | Revoke a key | | POST /web3/subscribe | tier (build or pro), payment-signature header | x402 USDC subscription (see flow below) |

Free-tier flow: Call /auth/web3/challenge with wallet address → sign the returned message with personal_sign (EIP-191) → submit to /web3/signup with the message and signature → receive API key.

Paid-tier flow (x402):

1. POST /web3/subscribe with { "tier": "build" } → server returns 402 with payment.amount (micro-USDC), payment.pay_to (treasury address), payment.network.
2. Sign an EIP-712 TransferWithAuthorization (EIP-3009) on USDC Base:
   • Domain: { name: "USD Coin", version: "2", chainId: 8453, verifyingContract: "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913" }
   • Type: TransferWithAuthorization(address from, address to, uint256 value, uint256 validAfter, uint256 validBefore, bytes32 nonce)
   • Message: { from: <wallet>, to: <pay_to>, value: <amount>, validAfter: 0, validBefore: <now+3600>, nonce: <32 random bytes hex> }
3. Build x402 v2 payment payload:

   {
     "x402Version": 2,
     "payload": {
       "signature": "0x<EIP-712 signature hex>",
       "authorization": {
         "from": "0x<wallet>",
         "to": "0x<pay_to from step 1>",
         "value": "<amount as string>",
         "validAfter": "0",
         "validBefore": "<unix timestamp as string>",
         "nonce": "0x<64 hex chars>"
       }
     }
   }
   

4. Base64-encode the JSON and retry: POST /web3/subscribe with { "tier": "build" } and header payment-signature: <base64 payload> → receive API key + subscription.

Important: All authorization values (value, validAfter, validBefore) must be strings, not numbers. See scripts/web3_subscribe.py for a complete working Python implementation.

Common Parameters

| Param | Type | Description | |-------|------|-------------| | start | int | Start timestamp (Unix ms). Defaults to 24h ago. | | end | int | End timestamp (Unix ms). Defaults to now. | | limit | int | Max records. Default 100, max 1000 (max 10000 for candles). | | cursor | string | Pagination cursor from meta.next_cursor. | | interval | string | Candle interval: 1m, 5m, 15m, 30m, 1h, 4h, 1d, 1w. Default: 1h. For OI/funding: 5m, 15m, 30m, 1h, 4h, 1d. Omit for raw data. | | depth | int | Orderbook depth (number of price levels per side). | | granularity | string | Lighter orderbook resolution: checkpoint (default), 30s, 10s, 1s, tick. | | account | int | Lighter L3 orderbook: filter by account index (e.g., 281474976710654 for LLP vault). |

Smart Defaults

When the user does not specify a time range, default to the last 24 hours:

NOW=$(( $(date +%s) * 1000 ))
DAY_AGO=$(( NOW - 86400000 ))

For candles with no explicit range, default to a range that makes sense for the interval (e.g., last 7 days for 4h candles, last 30 days for 1d candles).

Pagination

When meta.next_cursor is present in the response, more data is available. Append &cursor=VALUE to fetch the next page:

# First page
curl -s -H "x-api-key: $OXARCHIVE_API_KEY" \
  "https://api.0xarchive.io/v1/hyperliquid/trades/BTC?start=$START&end=$END&limit=1000"

# Next page (use next_cursor from previous response)
curl -s -H "x-api-key: $OXARCHIVE_API_KEY" \
  "https://api.0xarchive.io/v1/hyperliquid/trades/BTC?start=$START&end=$END&limit=1000&cursor=1706000000000_12345"

Tier Limits

| Tier | Price | Coins | Orderbook Depth | Lighter Granularity | Historical Depth | Rate Limit | |------|-------|-------|-----------------|---------------------|------------------|------------| | Free | $0 | BTC only (HIP-3: km:US500 only) | 20 levels | -- | 30 days | 15 RPS | | Build | $49/mo | All | 50 levels | checkpoint, 30s, 10s | 1 year | 50 RPS | | Pro | $199/mo | All | 100 levels | + 1s | Full history | 150 RPS | | Enterprise | Custom | All | Full depth | + tick | Full history | Custom |

Error Handling

| HTTP Status | Meaning | Action | |-------------|---------|--------| | 400 | Bad request / validation error | Check params (missing start/end, invalid interval) | | 401 | Missing or invalid API key | Set $OXARCHIVE_API_KEY | | 403 | Tier restriction | Upgrade plan (e.g., non-BTC coin on Free tier) | | 404 | Symbol not found | Check coin name spelling and exchange | | 429 | Rate limited | Back off and retry |

Error responses return { "code": 400, "error": "description" }.
