## 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-events-api-358492d5 -d '<json body>'
```

Example prompt: Fetch all Four.Meme events on BSC starting from block 45000000 up to block 45100000 so I can see which meme tokens were launched in that range.

## When to prefer this

Use this endpoint when you need raw on-chain event data from the Four.Meme protocol on BSC, particularly for monitoring token launches, tracking contract activity over a historical block range, or building analytics on top of Four.Meme meme coin activity. It is pay-per-request with no API key setup required, making it ideal for ad-hoc or agent-driven queries.

## Known failure modes

- Invalid or negative block numbers return an error
- fromBlock greater than toBlock causes an invalid range error
- BSC node unavailability may result in timeout or empty response
- Block range too large may cause performance degradation or timeout
- Payment failure via x402 protocol blocks the request

## 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

Returns a list of on-chain event logs emitted by the Four.Meme contract on BSC within the specified block range, including event types, transaction hashes, and relevant contract data for each event.
