## 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 convrgent-ai-f2dcacaa -d '<json body>'
```

Example prompt: Can you check the current emotional and cognitive state of user 'alex_smith_42' based on these three recent messages: 'I'm feeling a bit overwhelmed with work today', 'Things could be better, but I'm managing', and 'I hope tomorrow is a better day' — flag any stress or withdrawal signals across the 12 emotion categories?

## When to prefer this

Use this endpoint when you need a real-time snapshot of someone's current emotional and cognitive state from recent messages, especially when you want quadrant-based classification (stress/confidence/withdrawal/enthusiasm) across 12 emotion categories. Prefer this over the full psychological profile endpoint when recency matters and you want a lightweight, fast assessment of current mood rather than a deep personality portrait. Most valuable when paired with a vault profile for baseline delta comparison to understand mood shifts over time.

## Known failure modes

- Payment not provided or insufficient — returns x402 payment required error with accepted asset options
- Missing human_id or messages array — returns 400 validation error
- Empty or too-short messages array — insufficient signal for reliable detection
- Vault profile not found for human_id — baseline delta comparison unavailable, returns current state only
- Rate limit exceeded — returns 429 too many requests
- Invalid human_id format — returns error indicating unrecognized profile identifier

## How this service works

Current emotional and cognitive state detection from recent messages. Detects stress, confidence, withdrawal, enthusiasm across 12 emotion categories and 4 quadrants. With vault profile: baseline delta comparison.

## Output

Returns a structured emotional and cognitive state assessment covering 12 emotion categories and 4 quadrants (including stress, confidence, withdrawal, and enthusiasm scores). If a vault profile exists for the human_id, also returns a baseline delta showing how current state deviates from their historical norm.
