# Aether Base Token Risk Analyzer

> Aether Base Token Risk Analyzer is a paid API for AI agents from aether-x402.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Analyzes a Base ERC-20 token contract for risk flags, market data, and buy/sell simulation to produce a risk verdict and score.

## 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 aether-base-token-risk-analyzer-6a8dfc5b -d '<json body>'
```

Example prompt: Can you check the risk on this Base token at contract address 0x940181a94A35A4569E4529A3CDfB74e38FD98631 — run the buy/sell simulation and tell me if it's safe to trade?

## When to prefer this

Choose this endpoint when you need a fast, structured risk verdict for a specific Base network ERC-20 token — especially when you want automated buy/sell simulation, severity-labeled flags, and a numeric risk score in a single call. Prefer it over generic blockchain explorers when you need actionable 'safe/risky' verdicts rather than raw contract data, and over manual DeFi auditing tools when operating in an agent pipeline that requires programmatic JSON output paid per-call via USDC on Base.

## Known failure modes

- Invalid contract address format returns a validation error
- Contract address not deployed on Base returns no data or an error
- Token with no liquidity may return incomplete market data
- Simulation flag set to false skips buy/sell tax analysis
- Network or RPC errors on Base may cause timeout or partial response
- Payment failure via x402/USDC results in 402 response and no data returned

## How this service works

Pay-per-call Base onchain data, token risk verdicts and x402 payability audits over x402 (USDC on Base).

## Output

Returns a JSON object containing: an array of risk flags (each with an id, detail, and severity), market data (price in USD and liquidity in USD), the token symbol, a verdict string (e.g. 'low', 'medium', 'high'), a numeric risk score (0-100), and simulation results (buy/sell tax percentages, simulation outcome, and whether it was simulated).
