> Nami Cross-Venue Funding Rate Spread Snapshot is a paid API for AI agents from api.usenami.io, paid per call via x402, $0.001000/call, status unknown (last checked 2026-09-14).

## 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 api-usenami-io-156705da
```

Example prompt: What's the current funding rate spread for BTC across all perp exchanges — show me which venue has the highest and lowest rate and the spread in basis points?

## When to prefer this

Use this endpoint when you need an immediate, current cross-venue funding rate comparison for a specific symbol to identify arbitrage spreads or select the cheapest venue for a position. Prefer this over the historical rates endpoint when real-time spread is needed, and over the per-venue endpoint when you want the best/worst venue ranked automatically in a single call.

## Known failure modes

- Symbol not supported — returns 404 or empty result for tickers not tracked by Nami
- Rate limit or payment failure — 402 response if x402 micropayment not completed
- Venue data temporarily unavailable — partial snapshot if one or more venues are offline
- Invalid symbol format — malformed ticker returns 400 error
- Stale data — snapshot may lag by a few seconds during high-volatility periods
