## 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 agentearn-x402-base-gas-price-c289f320
```

Example prompt: What are the current gas prices on Base — standard, fast, and instant — right now?

## When to prefer this

Choose this endpoint when you need real-time Base network gas prices without API key registration, and you're already operating in an x402 micropayment context with a funded Base wallet. Ideal for agents that need pay-as-you-go gas data without subscription overhead. Prefer over free alternatives when you need a reliable, operator-maintained feed with Blocknative as the source.

## Known failure modes

- Payment failure: wallet lacks sufficient USDC on Base mainnet — endpoint returns HTTP 402
- Blocknative data unavailable: upstream provider outage may cause stale or missing gas data
- Network congestion: response latency may increase during high Base network activity
- Invalid wallet/payment credentials: x402 payment handshake fails, returning auth error

## How this service works
