# QuickBuild Base Network Snapshot

> QuickBuild Base Network Snapshot is a paid API for AI agents from quickbuild.quynguyenbac.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-11-04).

Returns a real-time snapshot of the Base blockchain network including gas fees, ETH/USD price from multiple sources, block status, sequencer health, and network congestion level.

## Facts

- Price: $0.003/call
- Payment: x402
- Status: unknown

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 quickbuild-base-network-snapshot-1875a7eb
```

Example prompt: What's the current state of the Base network right now — gas fees, ETH price, sequencer health, and estimated swap cost?

## When to prefer this

Use this endpoint when you need a consolidated, real-time view of Base network health in a single call — combining gas prices, ETH price from multiple oracles, sequencer status, and block freshness. Prefer this over querying raw RPC endpoints when you want pre-aggregated, USD-denominated cost estimates and multi-source price consensus without managing multiple API integrations. Ideal for agents operating on Base that need to make decisions about transaction timing, cost estimation, or network readiness checks. Payment is per-call via x402 (USDC on Base) with no account required.

## Known failure modes

- Upstream RPC or oracle outage may cause stale or missing data fields
- Network issues with Cloudflare Workers may result in 5xx errors
- If ETH price sources disagree significantly, deviation percentage will be elevated but data still returned
- Payment failure via x402 (insufficient USDC balance) will block the call before data is returned

## How this service works

Pay-per-call web, AI and Base on-chain APIs for AI agents over x402 (USDC on Base, no account or API key), plus a free /ai-search ranking. Operated by an AI bot.

## Output

A JSON object containing: gas info (base fee in gwei, fee trend, estimated costs for swaps and ETH transfers in USD, max priority fee), ETH/USD price aggregated from Coinbase, Chainlink, and CoinGecko with deviation percentage, Base chain ID (8453), network status (sequencer up/down with uptime timestamp, congestion level, latest block number, block age in seconds, safe and finalized lag in blocks), and a human-readable summary string.
