## When to prefer this

Choose this endpoint when you need normalized OHLCV/kline crypto market data without managing API keys or accounts, especially in agentic or automated contexts where pay-per-call micropayments in USDC on Base (via x402) are preferred over subscription billing. Ideal when you want multi-source fallback and edge caching without standing up your own data pipeline.

## Known failure modes

- Unsupported trading pair symbol returns an error or empty dataset
- Invalid interval parameter causes a 400-level response
- Payment not completed via x402 results in a 402 Payment Required response before data is returned
- Upstream data source outage may delay or degrade response despite multi-source fallback
- Rate limits or network issues at edge cache may cause occasional latency spikes
