## 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 tradesonar-funding-term-structure-a0ead281
```

Example prompt: Pull the funding term structure and regime for BTC-USD on TradeSonar so I can see whether funding is stable and what direction the curve is pointing.

## When to prefer this

Use this endpoint when you need granular funding rate analysis beyond a single spot rate — specifically the term structure shape, regime classification, and stability metrics for a dYdX perpetual market. Prefer this over generic market detail endpoints when your decision logic depends on whether funding is trending, mean-reverting, or in an extreme regime. Best suited for carry trade evaluation, funding arbitrage, or pre-trade risk checks on perpetual positions.

## Known failure modes

- Invalid ticker format (must be BASE-USD not BASE-USDT) returns an error; use /v1/markets to list valid tickers
- Ticker not found on dYdX returns a 404 or empty result
- Payment failure via x402 protocol blocks the request
- Rate limiting if too many calls are made in quick succession
- Stale data if dYdX on-chain data feed is temporarily delayed
