## 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 onchainpulse-robinhood-chain-uerc20-launchpad-live-feed-1fcba4ff
```

Example prompt: Show me the latest tokens that just launched through the Uniswap Liquidity Launchpad on Robinhood Chain — I want to see token addresses, launch times, and for the newest ones their name, symbol, holder count, and supply.

## When to prefer this

Use this endpoint when you need a live, trustless view of all token launches on Robinhood Chain's Uniswap Liquidity Launchpad, especially when no official front end or API exists for that launchpad. Ideal for agents monitoring new token activity, auditing launch history, or verifying whether a token was minted through the canonical UERC20Factory. Prefer over generic block explorers when you need structured, enriched launch metadata (name, symbol, holder count, supply) without parsing raw chain events.

## Known failure modes

- Chain RPC unavailability causes stale or failed data fetch
- Rate limiting or payment failure (x402) returns 402 Payment Required
- No launches yet returns an empty list
- Incomplete metadata on older tokens (name/symbol/holder count only on newest)
- Network congestion may delay newest block data

## How this service works

Live launch feed for Uniswap's Liquidity Launchpad on Robinhood Chain — every UERC20 token minted through the canonical UERC20Factory, newest first, read straight from chain state (the launchpad has no front end or API of its own). Per launch: token address, launch time, block, and for the newest: name, symbol, holder count, supply. Includes the canonical launchpad contract addresses and the safety facts common to all UERC20 tokens (fixed supply, no owner, no mint, no taxes by construction). Pai

## Output

A paginated list of UERC20 token launches on Robinhood Chain's Uniswap Liquidity Launchpad, sorted newest first. Each entry includes token contract address, launch timestamp, and block number. For the most recent launches: token name, symbol, holder count, and total supply. Also returns the canonical UERC20Factory and launchpad contract addresses, plus safety facts common to all UERC20 tokens (fixed supply, no owner, no mint function, no taxes).
