Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 no-hands-ai-base-gas-fee-quote-80c11cda
```

Example prompt: What are the current live gas fees on Base right now, and how much would a transaction cost with a gas limit of 100000?

## When to prefer this

Choose this endpoint when you need a real-time, ready-to-use gas fee quote for the Base L2 network with a cost estimate for a specific gas limit, especially within an autonomous agent pipeline that needs to gate transactions on current network costs. Prefer it over generic RPC calls when you want a simple, priced API response without managing your own Base node connection.

## Known failure modes

- Base RPC node unavailable or rate-limited — upstream data fetch fails
- Invalid or missing gas limit parameter — returns error or uses default
- Network congestion causing stale gas price data
- Payment not processed (x402 protocol failure) — call rejected before execution
- Cloudflare Worker timeout if upstream Base node is slow

## How this service works

Return live Base gas fees and an estimated transaction cost for a caller-supplied gas limit.

## Output

A live quote containing the current Base network gas price components (base fee, priority fee) and a calculated total estimated transaction cost in ETH and/or USD for the caller-supplied gas limit.
