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, prefix:NAME	km:US500, xyz:XYZ100
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.

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.

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" }.
