## 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-dydx-signals-api-d32d22d1
```

Example prompt: Pull the TradeSonar dYdX signals for BTC-USD — I want to see the current oracle price, the 1-day and 30-day annualized funding rates, and the open interest right now.

## When to prefer this

Choose this endpoint when you need dYdX-specific perpetual market signals — particularly funding rate term structure, open interest, and oracle pricing — with on-chain freshness guarantees (block-height stamping). Prefer it over generic crypto data APIs when the user is specifically trading or monitoring dYdX perpetuals and needs smart-money or crowding context alongside price data.

## Known failure modes

- Unknown or unsupported ticker returns 404 or empty data response
- Stale data if replica lag is high — check data_as_of block height before acting
- Rate limiting or payment failure (402) if x402 USDC micropayment is not properly handled
- Malformed ticker (e.g. incorrect format) may return validation error
- Temporary dYdX node outage may cause upstream data gaps

## How this service works

TradeSonar: dYdX on-chain smart-money, funding and crowding signals. Every response is stamped with data_as_of freshness (block height + replica lag).

## Output

A JSON object containing the ticker symbol, current oracle price, annualized funding rates at 1-day, 7-day, and 30-day horizons, the real-time annualized funding rate, and total open interest in USD — all stamped with a data_as_of field capturing block height and replica lag for freshness verification.
