## 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 speraxos-four-meme-token-list-api-435ca6bc -d '<json body>'
```

Example prompt: Show me the top 10 trending meme tokens on Four.meme right now, sorted by Hot, and flag any that have already graduated to PancakeSwap.

## When to prefer this

Use this endpoint when you need to discover, browse, or filter tokens launched on the Four.meme BNB Chain bonding-curve launchpad — especially when you need to sort by trending activity, new launches, trading volume, or graduation to PancakeSwap. Prefer this over generic DEX token lists when the user specifically wants meme launchpad tokens or wants to track bonding curve progression.

## Known failure modes

- Invalid label value returns empty results or error — must use exact enum: Meme, AI, Defi, Games, Infra, De-Sci, Social, Depin, Charity, Others
- pageSize exceeding 100 may return validation error
- Payment not received (x402 protocol failure) results in 402 response with no data
- Invalid orderBy value may cause unexpected sort or error
- No tokens matching filters returns empty list rather than an error

## How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

## Output

A paginated list of token records from the Four.meme launchpad, each including token name, symbol, label/category, bonding curve progress, 24-hour trading volume, graduation status, and other metadata relevant to on-chain meme token discovery.
