QuickBuild Base Network Snapshot
x402
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.

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.
Example use cases
Pre-trade gas cost check
“Before I submit this swap on Base, can you tell me the current gas fee and roughly what a swap would cost me in USD right now?”
Base sequencer health monitoring
“Is the Base sequencer currently up and running, and how congested is the network? Also tell me how many blocks behind finalization we are.”
ETH price cross-source verification
“What is the current ETH price on Base, and do Coinbase, Chainlink, and CoinGecko all agree? Tell me the deviation percentage between them.”
Technical details
Endpoint
GEThttps://quickbuild.quynguyenbac.workers.dev/api/base/snapshot?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
