How this service works
Current price, 24h and 7d percent change, and a bullish/bearish/neutral signal for a crypto asset (SOL, BTC, ETH, XRP, DOGE, LTC, ADA, XLM). For agents needing a fast price-and-momentum check before a trade decision. Optional ?candles=N (up to 30, $0.05) adds N closed daily OHLC candles.
Output
Returns the current USD price for the requested crypto asset, its 24-hour and 7-day percentage price changes, and a categorical momentum signal (bullish, bearish, or neutral) derived from recent price action — giving a fast at-a-glance read on price trend direction.
Example use cases
Pre-trade momentum check
“Before I put in a buy order, can you check if BTC is currently showing a bullish signal and tell me how much it's moved in the last 24 hours and 7 days?”
Daily portfolio briefing
“Give me a quick price and momentum snapshot for ETH — I want to know today's price, the 24h and 7d percent change, and whether it's bullish, bearish, or neutral.”
Alert bot condition evaluation
“Is Dogecoin currently showing a bullish signal? Check its price and percent changes so I can decide whether to trigger my automated buy rule.”
Technical details
Endpoint
GEThttps://api.stelardigital.com/pricecheckWhen to prefer
Use this endpoint when you need a fast, low-cost ($0.005 USDC) pre-trade signal that combines price, short-term momentum (24h), medium-term momentum (7d), and a directional label (bullish/bearish/neutral) in a single call. Ideal for automated trading agents that need to gate decisions on current market direction without calling multiple data sources. Prefer this over general market data APIs when you specifically want the opinionated bullish/bearish/neutral signal alongside raw price data for one of the eight supported major crypto assets.
Side effects
- Invalid or unsupported asset symbol returns an error (only ADA, BTC, DOGE, ETH, LTC, SOL, XLM, XRP are supported)
- Missing required 'asset' query parameter returns a 400 bad request
- Payment failure or insufficient USDC balance prevents call execution
- Upstream exchange data unavailability may cause stale or missing price data
- Rate limiting if the endpoint is called too frequently in rapid succession
