## 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 anicca-x402-funding-rate-arbitrage-469219d3
```

Example prompt: What are the current funding rates for BTC across all exchanges, and which pairs show the best arbitrage opportunity right now?

## When to prefer this

Choose this endpoint when you need real-time, cross-exchange crypto funding rate data without managing any upstream API keys — it bundles exchange data access and payment into a single keyless $0.003/call. Prefer it over self-managed exchange APIs when you want zero credential overhead, when building ephemeral or serverless agents, or when you need funding rate arbitrage signals derived across multiple venues simultaneously rather than querying each exchange individually.

## Known failure modes

- Payment not processed or insufficient USDC balance — 402 Payment Required
- Invalid symbol provided — may return empty results or error
- Exchange data temporarily unavailable — upstream feed outage
- Network timeout on the Tailscale-hosted endpoint
- Rate limit exceeded if called too frequently without valid payment

## How this service works

Live web search (keyless — no Exa/API account needed, we pay upstream) and real-time cross-exchange crypto funding-rate data + arbitrage signals, paid per call in USDC on Base via x402. For AI agents that need live data without holding any API keys.

## Output

A JSON response containing real-time funding rate data across multiple crypto exchanges, either filtered to a specific base asset (e.g. BTC) or covering the top 20 assets by spread. Includes per-exchange funding rates and derived arbitrage signals highlighting where rates diverge most significantly.
