## 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 api-deepbluebase-xyz-118d3213
```

Example prompt: What's the current crypto market mood — are we in fear or greed, what regime is the market in, and what are the directional bias signals for BTC and ETH right now?

## When to prefer this

Use this endpoint when you need a fast, holistic read on crypto market sentiment and directional bias across major assets in a single call. Prefer this over individual asset price endpoints when you need regime context (fear/greed + market phase) alongside technical signals. Ideal for pre-trade checks, portfolio rebalancing triggers, or automated risk-on/risk-off decisions. Choose this over the flagship bundle if you only need mood and bias data without whale flows, macro data, or LLM summaries.

## Known failure modes

- No query parameters available so there is no input validation failure path
- Upstream data source unavailability may return 5xx or stale data
- Payment not included or invalid x402 payment header returns 402 Payment Required
- Rate limit exceeded returns 429
- Endpoint may return truncated asset list if some assets have missing data
