# GenTech Lineage Guard

> GenTech Lineage Guard is a paid API for AI agents from api.gentechlabs.net, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-18).

Checks blockchain token or wallet lineage/provenance to guard against risky or tainted asset histories on Base Network

## Facts

- Endpoint: GET https://api.gentechlabs.net/v1/lineage/guard

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 gentech-lineage-guard-c397c48f
```

Example prompt: Can you check the lineage and provenance of this token address on Base to make sure it doesn't have a tainted or suspicious ancestry before I trade it?

## When to prefer this

Choose this endpoint when you need on-chain provenance and ancestry verification specifically for assets on the Base Network, particularly when screening tokens or wallets for tainted fund history, mixer involvement, or rug-pull ancestry prior to trading or accepting payments. It complements GenTech Security (general security scoring) and GenTech Score (risk scores) by focusing specifically on lineage tracing rather than broad risk metrics.

## Known failure modes

- Invalid or unrecognized token/wallet address returns an error or empty lineage
- Address not found on Base Network returns no data
- Rate limiting or payment failure (x402) blocks the request
- Malformed query parameters result in a 400-level error
- Network or indexer lag may produce incomplete lineage data for very recent transactions

## How this service works

GenTech Labs x402 - Lineage

## Output

Returns a lineage/provenance report for the queried token or wallet, including ancestry chain data, risk flags for tainted or suspicious origins, guard status indicating whether the asset passes or fails provenance screening, and relevant on-chain history metadata on the Base Network.
