## When to prefer this

Use this endpoint when you need real-time, verifiable on-chain oracle price data for a specific token across one of 46 supported blockchains, especially in DeFi automation, arbitrage detection, portfolio valuation, or any agent workflow requiring trustworthy token prices with pay-per-request flexibility.

## Known failure modes

- Unsupported token symbol or contract address returns 404 or error
- Unsupported or unrecognized chain returns an error response
- Missing required token query parameter returns 400 bad request
- Payment not fulfilled (x402) results in 402 Payment Required
- Network or RPC issues on the target chain may cause delays or errors
- Rate limiting or quota exceeded for the pay-per-request model
