## 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 klymax402-funding-arbitrage-scanner-a2de1969
```

Example prompt: Can you scan all crypto assets for funding rate arbitrage opportunities right now and tell me which ones have the best spread across venues?

## When to prefer this

Use this endpoint when you need a real-time scan of funding rate discrepancies across multiple DeFi/crypto venues to identify arbitrage opportunities, especially when you want a single aggregated view rather than querying each exchange individually. Best for traders or agents monitoring funding rate spreads programmatically.

## Known failure modes

- Invalid or unsupported symbol returns empty results or error
- Payment failure due to insufficient USDC on Base
- Venues temporarily offline reduce opportunity data coverage
- Rate limiting if called too frequently
- Network timeout if venues are slow to respond

## How this service works

One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.

## Output

Returns a JSON object containing: number of results found, the symbol filter applied, number of venues online, a list of arbitrage opportunities, the best opportunity details, and the total number of assets scanned.
