How this service works
On-demand crypto market data. Discover available trading pairs for free, then retrieve live prices, market metadata, and historical candlesticks when you need them.
Output
Returns a JSON object keyed by trading symbol, each containing the symbol's trading status (e.g. TRADING), base asset, quote asset, quote precision, base asset precision, and quote asset precision values.
Example use cases
Validating crypto pairs before trading
“Before I place any orders, can you check whether BTCUSDT and SOLUSDT are actively trading and tell me their base and quote asset details?”
Building a trading bot with precision data
“I'm setting up automated trades and need the exact quote and base asset precision for BTCUSDT, ETHUSDT, and BNBUSDT so I can format my order sizes correctly.”
Verifying exchange pair composition
“Can you confirm what assets make up the ETHUSDT and ADAUSDT pairs — like which is the base and which is the quote — and what their precision levels are?”
Technical details
Endpoint
POSThttps://x402-crypto-market-data.up.railway.app/symbol-infosWhen to prefer
Use this endpoint when you need structured trading metadata — asset composition, precision, and status — for multiple crypto pairs at once. It is distinct from price endpoints: it returns exchange configuration data, not live prices or historical candlesticks. Prefer this when building trading bots that need precision settings, validating whether pairs exist and are active, or enriching a list of symbols with metadata before further processing.
Side effects
- Fewer than 2 symbols provided — API requires minItems: 2
- More than 10 symbols provided — API enforces maxItems: 10
- Unknown or invalid symbol names result in missing or empty entries in the response
- Payment failure via x402 protocol blocks access to paid response
- Network timeout from Railway-hosted service under load
