## When to prefer this

Choose this endpoint when you need real-time, decentralized oracle-sourced cryptocurrency prices anchored to the Flare network's FTSO system, especially when you want tamper-resistant, consensus-based pricing rather than a centralized exchange feed. Ideal for DeFi applications, portfolio valuation, and cross-checking on-chain oracle data.

## Known failure modes

- Invalid or unsupported symbol in the path returns an error or omits that symbol from the response
- Malformed symbols path parameter results in a 400-level error
- Network latency or FTSO data provider downtime may result in stale or unavailable prices
- Payment failure (x402) results in a 402 response before data is returned
