Endpoint
GEThttps://anibalb.duckdns.org/x402/polkadot-price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick Polkadot spot price without setting up accounts or API keys — it charges $0.001 USDC per call via x402, making it suitable for low-frequency checks, agent pipelines, or environments where traditional API key management is impractical. Prefer a dedicated crypto data provider (e.g. CoinGecko, CoinMarketCap) if you need historical data, order book depth, or high-frequency polling.
