## When to prefer this

Use this endpoint when you need real-time, on-chain oracle price data for a specific token across a supported blockchain. Prefer this over off-chain price APIs when you need verifiable, oracle-sourced pricing for DeFi applications, risk calculations, or smart contract interactions. ChainRay covers 46+ chains making it suitable for multi-chain price lookups.

## Known failure modes

- Token symbol or contract address not found — returns 404 or empty result
- Unsupported chain identifier — returns error indicating chain is not available
- Payment not processed or insufficient USDC balance — returns 402 Payment Required
- Rate limit exceeded — returns 429 Too Many Requests
- Oracle feed unavailable or stale data — returns error or degraded response
