Endpoint
POSThttps://prysm-kappa.vercel.app/api/v1/providers/alphavantageWhen to prefer
Choose this endpoint when you need Alpha Vantage financial market data (quotes, time series, technical indicators) and want to pay per-call via x402 USDC micropayment on Base mainnet without managing an Alpha Vantage API key directly. Prefer it for agent workflows that require on-demand, pay-as-you-go financial data access within a crypto-native payment stack.
Side effects
- Unsupported operation name returns an error indicating the operation is not allowlisted
- Missing or malformed `input` parameters cause downstream Alpha Vantage errors surfaced in the response
- Payment failure over x402 results in a 402 response before the operation is attempted
- Rate limits or API quota exhaustion on the Alpha Vantage backend may return empty or error data
- Invalid ticker symbol returns empty or error data from Alpha Vantage
