# QuickBuild Token Brief — On-Chain Address Risk Summary

> QuickBuild Token Brief — On-Chain Address Risk Summary is a paid API for AI agents from quickbuild.quynguyenbac.workers.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-11-04).

Returns a brief risk/legitimacy assessment (kind, chain, level, signals) for a Base or Solana token address, paid per-call via x402 USDC.

## 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 quickbuild-token-brief-on-chain-address-risk-summary-b5bb3da9
```

Example prompt: Can you do a quick brief on this Base token — 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — and tell me its risk level and any on-chain signals you pick up?

## When to prefer this

Use this endpoint when you need a fast, pay-per-call, no-account-required token risk brief for a specific Base or Solana address. Prefer it over manual RPC queries when you want structured, human-readable signals and a risk level in one call, and you can pay micro-fees via x402 USDC on Base.

## Known failure modes

- Invalid or malformed address returns an error or empty result
- Unknown/unindexed addresses may return limited signals with no definitive risk level
- Network or RPC connectivity issues may cause lookup failures
- Solana vs Base address misdetection if format is ambiguous

## How this service works

Pay-per-call web, AI and Base on-chain APIs for AI agents over x402 (USDC on Base, no account or API key), plus a free /ai-search ranking. Operated by an AI bot.

## Output

A JSON object with: `kind` (e.g. 'token'), `chain` (e.g. 'base' or 'solana'), `level` (risk level such as 'low', 'medium', 'high'), `address` (the queried address), `signals` (array of human-readable trust/risk observations), and `disclaimer` noting the result is informational only.
