## When to prefer this

Choose this endpoint when you need verified, on-chain-settled BTC-USD candlestick data and are comfortable with a micro-payment per call via x402/USDC on Base. Ideal for agents that require trustworthy, auditable market data rather than free or unverified price feeds.

## Known failure modes

- Payment not received or insufficient USDC balance — 402 Payment Required returned
- Market or symbol not found — endpoint may return 404 if the market identifier is invalid
- Upstream data unavailable — service may return 503 if the underlying blockchain data source is down
- Rate limiting — too many requests may result in throttling
