name: 0xarchive version: 1.5.0 description: > Query historical crypto market data from 0xArchive across Hyperliquid, Lighter.xyz, and HIP-3. 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
  }
}

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.
