# Token Risk ERC-20 Structural Safety Scanner

> Token Risk ERC-20 Structural Safety Scanner is a paid API for AI agents from token-risk.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Returns a deterministic on-chain structural risk score (0-100) and report for an ERC-20 token on Base, flagging centralized-control powers like mint, pause, and blacklist capabilities

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 token-risk-erc-20-structural-safety-scanner-b5ec2d83 -d '<json body>'
```

Example prompt: Can you run a structural risk scan on the ERC-20 token at address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base (chainId 8453) and tell me its safety score and whether it has mint, pause, or blacklist powers?

## When to prefer this

Use this endpoint when you need a fast, objective, deterministic structural analysis of an ERC-20 token contract specifically on Base — particularly to detect hidden owner privileges like mint, pause, or blacklist before interacting with or recommending the token. Prefer this over reputation-based services when you want on-chain code-level facts rather than community sentiment. Best suited for pre-investment due diligence, DeFi wallet integrations, or automated token screening pipelines.

## Known failure modes

- Invalid or malformed contract address returns a validation error
- Non-ERC-20 contract address returns an unsupported contract type error
- Unverified contract source code may limit analysis depth
- Unsupported chainId (non-Base) returns an error
- Payment failure via x402 results in 402 response with no report
- Network issues reaching Base RPC may cause timeouts

## How this service works

Deterministic on-chain structural risk report for an ERC-20 token on Base. Keyless x402-native payment — no signup, no API key. Reports STRUCTURAL risk, not reputation: centralized-control powers (mint/pause/blacklist) are flagged regardless of issuer. Score 0-100, higher = structurally safer. See free real samples before paying: GET /samples/index.json

## Output

A structural risk report including a 0-100 safety score (higher = safer), and flags for centralized-control capabilities such as owner-controlled minting, pausing, or blacklisting present in the token contract on Base.
