# Aster Futures Skill Futures request on Aster using authenticated API endpoints. Authentication uses EIP-712 ECDSA signing with API wallet (main wallet + signer wallet). Return the result in JSON format. ## Data Fetching Guidelines (CRITICAL) **NEVER truncate JSON responses** with `head -c`, `head -n`, or similar — truncated JSON is corrupted and will produce wrong results. ### Mandatory Rules 1. **Always specify `symbol` parameter** when querying a specific trading pair. Many endpoints return ALL symbols when `symbol` is omitted, producing responses of 100KB+. 2. **Always use `limit` parameter** to constrain result size. Use the smallest limit that satisfies the request (e.g., `limit=5` instead of default 500). 3. **Use `jq` to extract fields** — never parse raw mega-JSON visually. Pipe through `jq` to select only needed data. ### Progressive Data Exploration Strategy When the user asks a broad question (e.g., "what futures are available?"), use a **layered approach**: 1. **Step 1 — Get lightweight summary first:** ```bash # Get just the symbol list, not full exchangeInfo curl -s "https://fapi.asterdex.com/fapi/v3/exchangeInfo" | jq '[.symbols[].symbol]' ``` 2. **Step 2 — Confirm scope with user** before fetching detailed data for many symbols. 3. **Step 3 — Fetch details for specific symbols only:** ```bash # Get price for ONE symbol, not all curl -s "https://fapi.asterdex.com/fapi/v3/ticker/price?symbol=BTCUSDT" ``` ### Endpoints That Return Dangerously Large Data (without symbol filter) | Endpoint | Without `symbol` | With `symbol` | |----------|------------------|---------------| | `/fapi/v3/exchangeInfo` | ALL symbols + filters (100KB+) | N/A — use `jq` to filter | | `/fapi/v3/ticker/24hr` | ALL symbols (50KB+) | Single object (~500B) | | `/fapi/v3/ticker/price` | ALL symbols (10KB+) | Single object (~80B) | | `/fapi/v3/ticker/bookTicker` | ALL symbols (20KB+) | Single object (~150B) | | `/fapi/v3/premiumIndex` | ALL symbols (30KB+) | Single object (~300B) | | `/fapi/v3/depth` | N/A (symbol required) | Varies by `limit`: use `limit=5` for overview | | `/fapi/v3/klines` | N/A (symbol required) | Default 500 candles — always set `limit` | | `/fapi/v3/trades` | N/A (symbol required) | Default 500 trades — always set `limit` | ### Example: Safe vs Unsafe ```bash # BAD — returns ALL symbols, then truncates = corrupted JSON curl -s ".../fapi/v3/ticker/price" | head -c 5000 # GOOD — returns single symbol, complete JSON curl -s ".../fapi/v3/ticker/price?symbol=BTCUSDT" # BAD — 500 candles by default curl -s ".../fapi/v3/klines?symbol=BTCUSDT&interval=1h" # GOOD — only 5 candles curl -s ".../fapi/v3/klines?symbol=BTCUSDT&interval=1h&limit=5" # GOOD — extract just symbol names from exchangeInfo curl -s ".../fapi/v3/exchangeInfo" | jq '[.symbols[] | {symbol, status}]' ``` --- ## Quick Reference | Endpoint | Description | Required | Optional | Authentication |
