## How to call it through Zero

## When to prefer this

Choose this endpoint when you need a lightweight, no-subscription, pay-per-call gas price lookup for the Base L2 network (eip155:8453) and are already operating in an x402/USDC micropayment context. It is ideal for autonomous agents that need on-demand gas fee data without managing API keys or monthly billing. Prefer alternatives if you need gas price data for chains other than Base, or if you need historical gas price time series rather than the current spot value.

## Known failure modes

- Payment failure: x402 payment not accepted or USDC balance insufficient — returns 402 Payment Required
- Network unavailable: Base RPC node unreachable — returns 5xx server error
- Rate or transient error: temporary service disruption — returns 5xx
- Invalid request format: malformed query parameters — returns 4xx

## How this service works

Fast, low-cost Base data for autonomous agents. No API keys, no subscriptions; pay per call with USDC over x402.

## Output
