## When to prefer this

Choose this endpoint when you need a quick, single-call snapshot of current Ethereum gas prices across all tiers (safe/standard/fast) plus the EIP-1559 base fee, without needing address-specific or transaction-specific data. It is ideal for pre-flight checks before submitting transactions, DeFi automation bots deciding when to execute, or dashboards that display live Ethereum network fee conditions.

## Known failure modes

- Unsupported chain parameter (only 'eth' is currently valid — other chains return an error)
- Etherscan API downtime or rate limiting may cause stale or unavailable data
- Network connectivity issues to the x402financialdata.com endpoint
- Payment failure (insufficient USDC balance for the $0.01/call fee)
