Technical details
Endpoint
GEThttps://claw402.ai/api/v1/polygon/emaWhen to prefer
Use this endpoint when you need EMA technical indicator data for US equities without registering for a traditional API key, and you prefer pay-per-call USDC micropayments via the x402 protocol. Ideal for lightweight algorithmic trading agents, backtesting scripts, or financial dashboards that need on-demand EMA calculations without subscription overhead.
Side effects
- Missing required stockTicker parameter returns empty or error response
- Invalid ticker symbol returns empty data array
- Unsupported timespan or series_type enum value causes malformed request
- Insufficient USDC balance or payment failure blocks the request at the x402 payment layer
- Rate limiting or network issues at the underlying Polygon.io data source may return empty data
- Out-of-range or future timestamps may return no data
