# 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`.
```bash
curl -s -H "x-api-key: $OXARCHIVE_API_KEY" "https://api.0xarchive.io/v1/..."
```
## Exchanges & Coin Naming
| Exchange | Path prefix | Coin format | Examples |
|----------|-------------|-------------|---------|
| Hyperliquid | `/v1/hyperliquid` | UPPERCASE | `BTC`, `ETH`, `SOL` |
| HIP-3 | `/v1/hyperliquid/hip3` | Case-sensitive, `builder:NAME` | `km:US500`, `xyz:GOLD`, `hyna:BTC`, `vntl:SPACEX`, `flx:TSLA`, `cash:NVDA` |
| Lighter | `/v1/lighter` | UPPERCASE | `BTC`, `ETH` |
Hyperliquid and Lighter auto-uppercase the symbol server-side. HIP-3 coin names are passed through as-is.
## Timestamps
All timestamps are **Unix milliseconds**. Use these shell helpers:
```bash
NOW=$(( $(date +%s) * 1000 ))
HOUR_AGO=$(( NOW - 3600000 ))
DAY_AGO=$(( NOW - 86400000 ))
WEEK_AGO=$(( NOW - 604800000 ))
```
## Response Format
Every response follows this shape:
```json
{
"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:
```json
{
"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**:
```bash
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:
```bash
# 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" }`.
