## 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 clearcheck-solana-creator-history-check-f9aa6f21
```

Example prompt: Can you check the creator history for the Solana coin with mint address 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU — how many coins have they launched and what's their graduation vs collapse rate?

## When to prefer this

Use this endpoint when you need to evaluate the trustworthiness of a Solana coin creator before investing, or when investigating whether a wallet is a serial memecoin launcher with a history of collapses. Prefer this over generic blockchain explorers when you specifically want a structured graduation/collapse rate verdict rather than raw transaction data.

## Known failure modes

- Mint address not found on-chain — creator cannot be looked up
- Wallet address has no launch history — returns null or empty results
- Invalid mint or wallet address format — query returns error
- Creator's recent coins unavailable due to lookup failures — recentOutcomes.lookupFailures > 0
- Render cold start delay causing slow or timed-out response
- Market cap data unavailable for very new or illiquid coins

## How this service works

Who launched this Solana coin, and did their other coins graduate or collapse? Serial launcher check.

## Output

Returns the creator's wallet address, total number of coins launched, launch counts for the last 24h and 7 days, a list of recent coins with their status (graduated/collapsed), market cap and peak market cap, graduation rate percentage, collapse rate percentage, and a plain-language verdict with supporting reasons. Also includes a disclaimer and the data retrieval timestamp.
