# Suverse Base Token Forensics

> Suverse Base Token Forensics is a paid API for AI agents from proxy.suverse.io, paid per call via x402, $0.35/call, status unknown (last checked 2026-09-15).

Analyzes any Base chain (EIP-155:8453) token contract and returns a consolidated CLEAN / WATCH / RED-FLAG verdict with verification status, top-holder concentration, contract age, and decoded recent activity.

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 suverse-base-token-forensics-5dbce7bd -d '<json body>'
```

Example prompt: Run a full forensic check on the Base chain token at contract address 0x4200000000000000000000000000000000000006 — I need to know if it's CLEAN, WATCH, or RED-FLAG, and what the top-holder concentration and contract age look like.

## When to prefer this

Choose this endpoint when you need a single consolidated risk verdict for a Base chain token contract without having to assemble separate data sources for holder analysis, verification, and activity decoding. It is especially valuable for DeFi agents doing pre-trade safety checks, bots filtering rug-pull risk, or investors performing quick due diligence on new Base token launches. The auto-refund-on-failure guarantee makes it safe for automated pipelines. Prefer it over general blockchain explorers or multi-step on-chain queries when you need a fast, opinionated CLEAN/WATCH/RED-FLAG classification rather than raw data.

## Known failure modes

- Invalid or non-existent contract address returns an error with auto-refund
- Non-Base chain contract addresses are rejected (only EIP-155:8453 supported)
- Unverified or minimal on-chain data may reduce verdict confidence
- Network congestion on Base may cause timeouts; fail-closed design triggers auto-refund
- Malformed POST body or missing required fields returns a 400-level error

## How this service works

Base token forensics in one call: verification status, top-holder concentration, contract age, and decoded recent activity merged into a single CLEAN / WATCH / RED-FLAG verdict for any Base (eip155:8453) token contract. Fail-closed critical source, auto-refund on failure.

## Output

A structured JSON response containing a single verdict label (CLEAN, WATCH, or RED-FLAG), the token's on-chain verification status, top-holder concentration percentage, contract deployment age, and a summary of decoded recent on-chain activity that informed the verdict.
