Endpoint
GEThttps://anibalb.duckdns.org/x402/crypto-ohlc?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need raw OHLC candlestick price data for a cryptocurrency with no API key signup, paying only per call in USDC on Base. Ideal for agents operating in a trustless, account-free environment or when integrating micro-payment workflows via x402. Not suited for streaming tick data or order book depth.
Side effects
- Missing or invalid cryptocurrency symbol returns an error or empty candles array
- Payment failure via x402 returns a 402 Payment Required response
- Unsupported trading pair may return no data or an error
- Network timeout if the upstream price data source is unavailable
- Invalid query parameters result in a 400-level error
