## 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 basefeed-gas-pulse-a681b815
```

Example prompt: What's the current gas price on Base right now? I want the live gas pulse reading before I submit a transaction.

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call real-time gas price check on the Base network without setting up a full RPC node or subscription. Ideal for agents that occasionally need current Base gas data before executing on-chain transactions or estimating costs.

## Known failure modes

- Network unavailability returns 5xx error
- Payment not settled via x402 returns 402 Payment Required
- Rate limiting may return 429 Too Many Requests
- Stale or unavailable on-chain data may result in delayed or empty response
