How this service works
Paid market-intelligence API over x402
Output
A JSON object containing: the volume-weighted median SOL/USD price, a timestamp (as_of), per-exchange breakdown (exchange name, price, volume, volume weight, included flag), a confidence label (e.g. 'high'), simple median price, cross-exchange spread percentage, data age in seconds, number of outliers rejected, and an informational disclaimer.
Example use cases
Live SOL price for trading bot
“Grab the latest Solana spot price right now — I need the volume-weighted median across exchanges with confidence level so my trading bot can decide whether to execute.”
Cross-exchange SOL spread monitoring
“What's the current cross-exchange spread on Solana? Pull the per-exchange prices and volume weights so I can see how fragmented the market is.”
Real-time SOL portfolio valuation
“I need the current Solana price in USD to value my portfolio — give me the multi-exchange aggregated figure with a timestamp so I know how fresh it is.”
Technical details
Endpoint
GEThttps://kronossignals.com/api/v1/price/solWhen to prefer
Choose this endpoint when you need a real-time, multi-source aggregated SOL/USD spot price with per-exchange transparency, volume weighting, and a confidence signal — particularly in automated agent or trading-bot contexts where paying $0.001 USDC per call via x402 is acceptable. Prefer it over single-exchange feeds when cross-exchange accuracy and outlier rejection matter.
Side effects
- Payment not received or x402 micropayment fails — endpoint returns 402 Payment Required
- Asset not supported or path misconfigured — may return 404 or empty response
- Exchange data unavailable — confidence may degrade or fewer sources included
- Stale data — data_age_seconds may be elevated if upstream feeds are slow
- Rate limiting or server error — returns 5xx with no price payload
