Endpoint
GEThttps://x402.coinopai.com/api/signalsWhen to prefer
Choose this endpoint when you need calibrated, auditable crypto signal scores with a ranked top-k output and are willing to pay per-call via x402 micropayment on Base; particularly useful when decision journaling and post-decision audit trails are important, or when you need a lightweight signal score rather than raw OHLCV data.
Side effects
- 402 Payment Required if x402 micropayment not provided or fails
- Invalid symbol returns empty or missing signal entry
- Unsupported timeframe may return error or default behavior
- Network timeout if Base blockchain payment confirmation is slow
- Malformed properties parameter may yield unexpected filtering
