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 anicca-x402-funding-rates-api-067f7bd8
```

Example prompt: What's the current 8-hour funding rate for BTC on Hyperliquid? I want to know if it's worth holding a long perp position right now.

## When to prefer this

Use this endpoint when an AI agent needs real-time perpetual futures funding rate data — especially for DeFi-native workflows settled in USDC via the x402 payment protocol. Prefer this over scraping exchange APIs directly when you need cross-exchange aggregation with divergence analysis included, or when operating in a micropayment-native agent environment where per-call USDC pricing is acceptable. Ideal for trading agents monitoring crowded trades, basis traders, and automated risk management workflows.

## Known failure modes

- Invalid symbol pattern (must be 1-20 alphanumeric chars) returns validation error
- Payment failure or insufficient USDC balance returns 402 Payment Required
- Exchange data temporarily unavailable sets degraded:true in response with partial results
- Unknown symbol returns empty rates array
- Service downtime returns 5xx error

## How this service works

Return live cross-exchange perpetual funding rates and the largest annualized funding divergences.

## Output

Returns a JSON object containing an array of funding rate entries (each with symbol, exchange, and 8h funding rate), a list of exchanges covered, the timestamp of generation, a divergence analysis for the top 20 assets, and a degraded flag indicating partial data availability.
