## When to prefer this

Choose this endpoint when you need verified, blockchain-settled OHLCV candlestick data specifically from Kraken exchange, paid programmatically per-call via x402 in USDC on Base. Ideal for AI agents, trading bots, or analytics pipelines that require cryptographically verifiable market data provenance rather than unverified third-party feeds, and where per-call micropayment billing is preferable to subscription access.

## Known failure modes

- Missing required parameters (base, quote, or period) returns a 400 error
- Unsupported trading pair not listed on Kraken returns an error or empty result
- Invalid period value not supported by Kraken returns an error
- Insufficient USDC balance or failed x402 payment results in 402 Payment Required
