# svm402 Base ERC-20 Token Forensics Report

> svm402 Base ERC-20 Token Forensics Report is a paid API for AI agents from svm402.com, paid per call via x402, $0.010000/call, status unknown (last checked 2026-09-15).

Returns a comprehensive on-chain forensics report for a Base ERC-20 token, including metadata, deployer profile, holder concentration, LP-lock heuristic, and risk flags.

## 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 svm402-com-e496fe16
```

Example prompt: Run a full on-chain forensics report on the Base ERC-20 token at address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — I want to see holder concentration, whether liquidity is locked, deployer holdings, and any risk flags like mintable or proxy-upgradeable.

## When to prefer this

Use this endpoint when you need a single-call comprehensive forensics summary of a Base ERC-20 token for due diligence, risk assessment, or agentic DeFi workflows — especially when you need holder concentration, deployer risk, and contract trait flags in one response rather than assembling them from multiple raw blockchain RPCs.

## Known failure modes

- Invalid or non-ERC-20 contract address returns an error or empty report
- Token not indexed on Blockscout may return incomplete data
- Non-Base chain addresses will not be resolved correctly
- Payment failure via x402/USDC prevents the call from completing
- Rate limiting or upstream Blockscout downtime may cause timeouts

## How this service works

On-chain forensics for a Base ERC-20 sourced from Blockscout: token metadata (name, symbol, decimals, total supply, financials, verified status), deployer profile (balance, creation, activity), token activity metrics, holder count, raw and circulating-supply-adjusted top-10 holder concentration, a per-holder breakdown of the top 10 with category tags (burn / bridge / deployer / contract / eoa / unknown), deployer holdings, an LP-lock heuristic, and descriptive attribute flags. Address is supplied via the `:address` path parameter. Pay-per-call via x402 / USDC on Base.

## Output

A structured JSON report including: token metadata (name, symbol, decimals, total supply, exchange rate, circulating market cap, verified status), deployer profile (balance, creation tx, activity), token activity metrics, holder count, raw and circulating-supply-adjusted top-10 holder concentration percentages, per-holder breakdown with category tags (burn/bridge/deployer/contract/eoa/unknown), deployer holdings percentage, LP-lock heuristic boolean, contract traits (mintable, pausable, ownable, blacklist, fee_setter, proxy_upgradeable), and descriptive risk flags array.
