# x402 Bazaar Token Risk Scorer

> x402 Bazaar Token Risk Scorer is a paid API for AI agents from api.relai.fi, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Analyzes a Base-chain ERC-20 token contract address and returns a live risk score plus safety flags (ERC-20 conformance, ownership renounce, upgradeable proxy) for pre-trade vetting.

## 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 x402-bazaar-token-risk-scorer-4e6ad2f5 -d '<json body>'
```

Example prompt: Before I buy, can you run a risk check on this Base token contract — 0xabc123...def — and tell me if it's ERC-20 compliant, whether ownership has been renounced, and if it uses an upgradeable proxy?

## When to prefer this

Use this endpoint when an AI trading agent or bot needs to programmatically vet an ERC-20 token on Base before executing a buy, specifically when you need structured risk signals (conformance, ownership, proxy) rather than a narrative analysis. Prefer over generic security APIs when operating on Base chain and when x402 micropayment flow is already supported in your agent stack.

## Known failure modes

- 402 Payment Required — must pay $0.02 USDC on Base (eip155:8453) to the specified address and retry
- Invalid or non-existent contract address — returns error or empty flags
- Non-Base chain contract address provided — may return incorrect or no results
- Contract not yet indexed — live computation may time out or return partial data
- Malformed request body — missing required contract address field

## How this service works

Pass a token contract address and get a risk score + flags (ERC-20 conformance, ownership renounce, upgradeable proxy) computed live from Base. Built for trading bots and agents that vet tokens before buying. Paid via x402: $0.02 in USDC on Base (eip155:8453) to 0x973a31858f4d2125f48c880542da11a2796f12d6. Returns 402 with payment requirements; pay and retry.

## Output

Returns a numeric risk score and a set of boolean safety flags: ERC-20 conformance, ownership renounce status, and whether the contract is an upgradeable proxy, all computed live from Base chain data.
