# ArgonautWorks Base Network Pulse API

> ArgonautWorks Base Network Pulse API is a paid API for AI agents from argonaut-base-network-pulse.vercel.app, paid per call via x402, $0.009/call, status unknown (last checked 2026-09-14).

Returns real-time Base mainnet block data, EIP-1559 gas fees, ETH/USD price from DEX and spot sources, and deepest WETH-stablecoin pool telemetry in a single call.

## Facts

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 argonautworks-base-network-pulse-api-1a454f89
```

Example prompt: What are the current gas fees, ETH price, and deepest WETH-stablecoin pool stats on Base mainnet right now?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
