## 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 funding-rates-decision-api-symbol-summary-e54664d6
```

Example prompt: What are the current funding rates for BTC across all supported perp venues — and which venue has the highest vs lowest annualized rate right now?

## When to prefer this

Choose this endpoint when an AI trading agent needs to compare funding rates across a broad set of centralized and decentralized perp venues in a single call. It is especially useful for funding rate arbitrage detection, venue selection for minimizing carry costs, or any workflow that needs both raw per-interval rates and pre-computed annualized spreads. Prefer this over venue-specific APIs when multi-venue breadth matters.

## Known failure modes

- 402 Payment Required — no valid MPP payment receipt attached; response body lists per-route price in USDC
- Unknown or unsupported symbol — may return empty records array or error
- Invalid venues parameter format — comma-separated list expected; malformed input may yield partial or no results
- Venue data unavailable — a specific venue may be missing from records if it is temporarily unreachable
- Rate limiting or infrastructure errors — 5xx responses if upstream data provider is down

## How this service works

Paid funding rate decision API for AI trading agents across up to 16 perp venues. Settled via x402 on Base mainnet (eip155:8453) using the Coinbase Mogami v2 facilitator; unpaid requests receive a 402 challenge that lists the per-route price.

## Output

A structured object containing per-venue funding rate records (rate, interval hours, funding kind, next funding time), a plain-language summary string, the venue with the highest and lowest annualized rate, the raw annualized spread and per-interval spread, and metadata including timestamp and source. Covers up to 16 venues including Binance, Bybit, Hyperliquid, Paradex, Backpack, and more.
