## 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 nonvisceral-eloisa-mousily-ngrok-free-dev-0bb80fcb
```

Example prompt: Give me a full crypto market snapshot right now — BTC and ETH prices, their RSI and funding rates, open interest, the Fear and Greed index, and whether the overall sentiment is bullish or bearish.

## When to prefer this

Choose this endpoint when you need a single low-cost call ($0.01) to bootstrap a trading agent's decision context with BTC, ETH, and gold prices plus technical indicators, funding rates, open interest, and sentiment — all in one response. Prefer it over calling individual signal endpoints separately when latency and cost efficiency matter, or when building a per-tick market snapshot for an automated trading loop.

## Known failure modes

- Payment not received or invalid x402 payment header — endpoint returns 402 Payment Required
- Upstream Hyperliquid DEX data unavailable — may return stale or partial asset data
- ngrok free-tier tunnel down or rate-limited — returns 502 or connection timeout
- GOLD regime field may be null if EMA signal is not computable
- ETH direction/regime may be null in low-volatility periods

## How this service works
