How this service works
A crypto market data agent that exposes live symbols, market metadata, and historical Binance candlesticks.
Output
Returns a JSON object with an 'infos' map keyed by symbol. Each entry contains: symbol name, trading status (e.g. TRADING), base asset ticker, quote asset ticker, quote precision, base asset precision, and quote asset precision. Supports up to 10 symbols per request.
Example use cases
Pre-trade symbol validation check
“Before I place any orders, check if SOLUSDT, BNBUSDT, and XRPUSDT are currently in TRADING status on Binance and give me their precision settings.”
Portfolio data enrichment pipeline
“I have a list of pairs — BTCUSDT, ETHUSDT, ADAUSDT, and DOTUSDT — can you pull their Binance metadata like base asset, quote asset, and precision so I can enrich my portfolio tracker?”
New trading pair research
“I'm considering trading AVAXUSDT and MATICUSDT — can you look up their Binance symbol info to confirm they're active and show me the asset details?”
Technical details
Endpoint
POSThttps://crypto-market-data.up.railway.app/symbol-infosWhen to prefer
Choose this endpoint when you need structured trading metadata (status, asset names, precision) for multiple Binance symbol pairs in a single call. Prefer this over general crypto price feeds when your use case is about symbol validation, precision configuration, or asset relationship lookups rather than live price data. Best suited for pre-trade validation, portfolio data enrichment, or building trading infrastructure that needs Binance-specific pair metadata.
Side effects
- Invalid or unrecognized symbol returns missing or empty entry for that symbol
- Fewer than 2 symbols provided triggers input validation error
- More than 10 symbols causes request rejection due to maxItems constraint
- Network or upstream Binance API outage may result in timeout or 5xx error
- Payment failure (x402) results in 402 response before any data is returned
