How this service works
Obol sells verified blockchain data over x402, settled in USDC on Base.
Output
Returns a JSON object containing the base and quote currency pair, the candle period in seconds, the exchange name (e.g. KRAKEN), an array of OHLCV candles ordered newest-first, and a coverage object describing maximum candles available, number returned, and the latest and earliest observed timestamps. Includes a disclaimer that data is for informational use only.
Example use cases

Technical details
Endpoint
GEThttps://obol.danieldutoit.net/v1/markets/candlesWhen to prefer
Choose this endpoint when you need verified, blockchain-settled OHLCV candlestick data for crypto markets and want payment handled automatically via x402 micropayments in USDC on Base. Prefer it over free APIs when data provenance and verification matter, or when building agent workflows that require trustless, pay-per-call access without API key management.
Side effects
- Unsupported trading pair returns empty candles array
- Invalid or unsupported exchange name returns error
- Payment failure via x402 protocol blocks data access
- No recent data available results in null timestamps and zero returned candles
- Rate limiting or micropayment settlement delay causes timeout
