## 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-6cd5c056
```

Example prompt: What's the current crypto market sentiment — is the consensus bullish or bearish right now, and is there a contrarian signal I should be aware of for short-term and long-term direction?

## When to prefer this

Use this endpoint when you need a pre-computed, multi-source consensus sentiment view for crypto/Bitcoin trading decisions, particularly when you want KOL signals, whale on-chain stance, and contrarian indicators combined into a single weighted score rather than raw individual feeds. Prefer this over raw social or on-chain feeds when you need a decision-ready signal without building your own aggregation logic.

## Known failure modes

- Stale data if upstream sentiment sources are delayed or unavailable
- HTTP 402 if payment is not included or USDC balance is insufficient
- HTTP 503 if the ngrok tunnel or underlying service is offline
- Empty or null fields if insufficient sources contributed to the panel at query time
- No coin-specific filtering — returns aggregate crypto/BTC sentiment only, not individual altcoins

## How this service works

Cryptocurrency market sentiment analysis API: bullish or bearish signal with strength score, short-term and long-term market direction, contrarian indicator from a weighted multi-analyst panel (KOL signals + on-chain whale stance + contrarian noise sources). Bitcoin and crypto sentiment data for trading agents. Returns composite direction with per-source weighting — a pre-computed consensus view rather than raw feeds.

## Output

Returns a composite sentiment object with: overall bullish or bearish direction, a strength score, short-term and long-term market direction objects, a contrarian indicator string, a contrarian strength score, a source count, and a last-updated timestamp — all derived from a weighted panel of KOL signals, on-chain whale stance, and contrarian noise sources.
