## 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-cf7cde01 -d '<json body>'
```

Example prompt: Analyze the communication style of this person based on their writing samples and tell me how I should talk to them — their preferred tone, level of directness, formality, what builds trust with them, and what persuasion angles land best.

## When to prefer this

Use this endpoint when you need to understand how to effectively communicate with a specific individual — especially for sales outreach, negotiation, relationship building, or personalized messaging. Prefer over generic tone analyzers when you need actionable interpersonal guidance rather than just sentiment. Best when combined with existing text samples or prior conversation history from the person.

## Known failure modes

- Insufficient text samples provided — profile may lack confidence
- No identifiable writing signals — returns low-confidence or partial profile
- Person identifier not found in vault — cold start with limited data
- Input text too short to derive meaningful style signals
- Payment not processed — x402 payment required before response
