# Agent Health Monitor – Base Wallet Health Analyzer

> Agent Health Monitor – Base Wallet Health Analyzer is a paid API for AI agents from agenthealthmonitor.xyz, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-14).

Analyzes a Base L2 wallet address and returns a composite health score, gas efficiency metrics, failure analysis, and actionable optimization recommendations.

## Facts

- Endpoint: GET https://agenthealthmonitor.xyz/health/*
- Price: $0.5/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 agent-health-monitor-base-wallet-health-analyzer-fd2974bc
```

Example prompt: Can you run a full health check on my Base agent wallet at 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 and tell me the health score, success rate, how much gas has been wasted, and what I should fix first?

## When to prefer this

Use this endpoint when you need a comprehensive, multi-dimensional diagnostic of a Base L2 wallet's on-chain behavior — especially for AI agent wallets that execute transactions autonomously. Prefer this over raw blockchain explorers when you want pre-computed health scores, failure categorization, and prioritized recommendations in a single API call rather than raw transaction data.

## Known failure modes

- Invalid or malformed wallet address returns an error status
- Wallet address with no transaction history may return empty or minimal report
- Rate limiting or payment failure (x402) if USDC payment not attached
- Network issues fetching on-chain data from Base L2 may cause timeouts
- Very new wallets with few transactions may produce low-confidence scores

## How this service works

Base blockchain agent wallet health analyzer. Returns health score, gas efficiency, failure analysis, and optimization recommendations for any Base L2 wallet address.

## Output

Returns a JSON report containing: composite health score (0–100), total/successful/failed transaction counts, success rate percentage, reverted/out-of-gas/nonce-gap counts, retry count, total and wasted gas in ETH, estimated monthly waste in USD, first/last seen dates, whether the address is a contract, optimization priority level (CRITICAL/HIGH/MEDIUM/LOW), and an array of categorized actionable recommendations with severity levels.
