> HoodGrow Base Mainnet Pre-Launch Token Registry is a paid API for AI agents from www.hoodgrow.com, paid per call via x402, $0.05/call, status down (last checked 2026-09-15).

Returns verified on-chain metadata and live totalSupply() liveness signals for pre-launch B20 native equity tokens on Base mainnet (chain 8453).

## Facts

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 hoodgrow-base-mainnet-pre-launch-token-registry-4dff7eec
```

Example prompt: Show me all the B20 native equity tokens that are currently in pre-launch status on Base mainnet — I want their on-chain metadata and a liveness check via totalSupply for each one.

## When to prefer this

Use this endpoint when you need a curated, verified list of equity tokens on Base mainnet that are specifically in pre-launch status — particularly useful for pre-launch discovery, due diligence on upcoming tokenized equities, or monitoring the pipeline of new B20 tokens before they go live. Prefer this over general block explorer queries when you need HoodGrow's verification layer and liveness signal bundled together.

## Known failure modes

- Payment not received or insufficient USDC — x402 payment required error returned
- No pre-launch tokens currently in registry — empty list returned
- Chain RPC timeout — totalSupply() liveness check may be stale or missing
- Token metadata not yet verified — partial records with missing fields
- Rate limiting if called too frequently without payment

## How this service works

HoodGrow — Base mainnet (chain 8453) native-equity-token registry: verified on-chain metadata and a liveness signal (totalSupply()) for tokens that are currently PRE-LAUNCH.

## Output

A list of pre-launch B20 native equity tokens on Base mainnet (chain 8453), each with verified on-chain metadata (name, symbol, contract address) and a liveness signal derived from a totalSupply() call, confirming the token contract is deployed and active but not yet publicly launched.
