## 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 swaphunt-fear-greed-sentiment-comparison-234debed
```

Example prompt: Show me how crypto market sentiment has been shifting — I want to see today's Fear and Greed score compared to yesterday, a week ago, and a month ago, with the deltas so I can tell if mood is improving or deteriorating.

## When to prefer this

Choose this endpoint when you need multi-timeframe sentiment momentum rather than just today's Fear & Greed number. Ideal for trading agents that need to know whether sentiment is accelerating into fear or greed, not just the current reading. Prefer over a single-point Fear & Greed lookup when directional trend and delta context matter for a decision.

## Known failure modes

- Upstream Fear & Greed data source unavailable — service may return 503 or stale data
- Payment of $0.002 USDC not completed via x402 protocol — returns 402 Payment Required
- Rate limiting if called excessively in a short window
- No query parameters accepted so malformed requests are unlikely, but missing x402 payment header returns 402

## How this service works

Fear & Greed now vs yesterday, 7 days and 30 days ago — with the deltas — so an agent can see whether market sentiment is improving or deteriorating, not just today's number. Use for momentum-of-mood.

## Output

A structured response containing Fear & Greed index values at four time horizons (now, yesterday, 7 days ago, 30 days ago) plus the numeric deltas between them, enabling the agent to assess whether market sentiment momentum is positive (trending greedy) or negative (trending fearful).
