## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability money-reactor-base-gas-price-api-5b277f58
```

Example prompt: What's the current gas price on Base right now — give me the base fee, gas price, and priority fee in Gwei?

## When to prefer this

Choose this endpoint when your agent needs real-time EIP-1559 gas parameters specifically for the Base L2 network, especially in a pay-per-call context with no API key setup. Ideal for agents that infrequently poll gas (avoiding subscription overhead) or need on-demand gas checks before executing on-chain transactions on Base.

## Known failure modes

- Base RPC node unavailable — may return 5xx or stale data
- Transient network congestion spikes may cause slightly delayed readings
- Payment failure via x402 if USDC balance is insufficient — call is rejected before execution
- Malformed request may return an empty or error JSON response
