## 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 unprice-gas-price-api-5189f5d9
```

Example prompt: What's the current gas price on the Base network — give me both the Gwei and Wei values?

## When to prefer this

Use this endpoint when you need real-time Base network gas prices in a pay-per-call model without API key setup, especially in automated agent workflows using x402 micropayments on Base. Prefer over free alternatives when you need reliable, monetized access without rate limits tied to API keys.

## Known failure modes

- Payment not included or insufficient USDC — returns HTTP 402 Payment Required
- Base node unavailable or rate-limited — may return 5xx error
- Malformed request — may return 400 with error details
- Network congestion causing stale or delayed gas data

## How this service works

## Output

A JSON object containing the network name ('base'), the current block number, the gas price in Wei as a string, and the gas price in Gwei as a float.
