Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| get_base_gasA | Returns live Base mainnet gas data (base fee, low/medium/high priority fees, and an ETH transfer cost estimate). IMPORTANT: every call makes a REAL $0.001 USDC payment on Base mainnet via the x402 protocol and requires a funded buyer wallet (BUYER_PRIVATE_KEY) holding USDC and ETH for gas. Do not call this repeatedly or in loops — each invocation spends real money. |

Only one tool exists, so there is no possibility of confusion or overlap between tools. The agent can clearly identify its single purpose.
The single tool name 'get_base_gas' follows a clear verb_noun pattern using snake_case. With only one tool, there is no inconsistency to evaluate.
One tool is on the lower bound of what is reasonable for a gas data server. While the narrow scope and real-money cost per call justify a minimal surface, it still feels thin.
The tool provides all essential live gas data (base fee, priority fees, transfer cost estimate) for the Base mainnet, fully covering the server's stated purpose without obvious gaps.
