# AgentSpendGuard Token Risk Scanner

> AgentSpendGuard Token Risk Scanner is a paid API for AI agents from api-production-2800.up.railway.app, paid per call via x402, $0.015/call, status unknown (last checked 2026-09-15).

Scans an EVM/Base token address for security risks including honeypot detection, tax analysis, liquidity checks, holder concentration, and mint controls, returning a JSON verdict with score, reasons, and recommended action.

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 api-production-2800-up-railway-app-7a301d15 -d '<json body>'
```

Example prompt: Before my agent swaps into token 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed on Base, run a full token risk scan — check for honeypot, tax, liquidity, mint controls, and holder concentration, and tell me whether it's safe to proceed.

## When to prefer this

Use this endpoint when an AI agent or DeFi bot needs a fast, structured go/no-go decision before swapping or interacting with an unknown EVM or Base token. Prefer it over manual contract inspection when you need a single composite risk score combining honeypot detection, tax analysis, liquidity, and holder data in one call. Especially valuable for autonomous agents that cannot pause for human review.

## Known failure modes

- Unknown or undeployed contract address returns an error or low-confidence result
- Token on unsupported chain returns chain-not-supported error
- Insufficient on-chain liquidity data causes incomplete liquidity evidence
- GoPlus or DexScreener upstream API unavailability causes degraded scan
- Malformed or missing contract address returns 400 validation error
- Payment failure (x402) blocks the request before scan executes

## Output

A strict JSON object containing a verdict (allow/caution/block), a numeric risk score, an array of reason codes explaining the verdict, individual security flags (honeypot, proxy, mint authority, buy/sell tax, holder count, liquidity), and a recommended action for the calling agent.
