# Wallet Intel API - Perpetual Funding Rates

> Wallet Intel API - Perpetual Funding Rates is a paid API for AI agents from wallet-intel-api-production-3ec7.up.railway.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-09).

Fetches perpetual futures funding rates for a single token or all 700+ pairs across multiple exchanges, returning annualized yield and directional trading signals.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 wallet-intel-api-perpetual-funding-rates-775f08ab
```

Example prompt: What are the current perpetual funding rates for ETH across all exchanges — give me the annualized yield and whether conditions are favorable for a long or short position?

## When to prefer this

Use this endpoint when you need real-time perpetual funding rates aggregated across multiple exchanges (Binance, Bybit, OKX, Gate) for crypto trading signals, carry trade discovery, or funding rate arbitrage analysis. It is especially useful when you want a ready-made directional signal and annualized yield without computing them yourself. Prefer it over raw exchange APIs when you need multi-exchange aggregation in a single call.

## Known failure modes

- Symbol not found: unsupported or misspelled token symbol returns empty or error
- Exchange unavailable: one or more exchanges may be down, reflected in exchangeStatus booleans
- Payment failure: x402 micropayment not processed, returns 402 with payment required
- Rate limit exceeded: too many requests in a short period
- Network timeout: Railway-hosted service may be temporarily unreachable

## How this service works

Perpetual funding rates from multiple exchanges. Returns funding rate, annualized yield, directional signal. Query single token or all pairs.

## Output

Returns an array of per-exchange funding rate entries (exchange name, mark price, index price, funding rate, next funding time), plus aggregated fields: average funding rate across exchanges, annualized yield percentage, directional signal (long_favorable / short_favorable / neutral), timestamp, exchange availability status for Binance/Bybit/OKX/Gate, and the queried symbol.
