How this service works
Current Base mainnet block consensus, EIP-1559 fees, ETH/USD reference price, and deepest WETH-stablecoin DEX pool telemetry.
Output
A JSON object containing: current Base mainnet block number; EIP-1559 gas price and priority fee in gwei; ETH/USD price from both Base DEX and Coinbase spot with the premium in basis points; the deepest WETH-stablecoin pool's DEX name, liquidity in USD, and 24h volume in USD; consensus health metrics (block spread, configured and responsive source counts); and overall network status string.
Example use cases
Gas cost check before on-chain transaction
“Before I submit this Base transaction, can you check the current EIP-1559 gas price and priority fee on Base mainnet so I know what it'll cost?”
DEX vs. spot price arbitrage monitoring
“Is the ETH price on Base DEX trading at a premium or discount versus Coinbase spot right now, and by how many basis points?”
DeFi liquidity dashboard snapshot
“Give me a snapshot of the deepest WETH-stablecoin pool on Base — which DEX, how much liquidity, and what's the 24-hour volume?”
Technical details
Endpoint
GEThttps://argonaut-base-network-pulse.vercel.app/api/v1/pulseWhen to prefer
Choose this endpoint when you need a single-call snapshot of Base mainnet health, gas fees, ETH price, and DEX liquidity in one response — especially useful for DeFi agents that need to price transactions, detect arbitrage, or gate actions on network health without making multiple separate RPC and API calls.
Side effects
- Network or RPC unavailability may return a degraded or error status
- Stale block data if upstream Base node is lagging
- DEX pool data may be missing if liquidity indexer is unreachable
- HTTP 402 if payment is not included or insufficient
- Partial data returned if one of the configured consensus sources is unresponsive
