## 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 vidar-agent-general-conversational-ai-53cf909c -d '<json body>'

Example prompt: Can you chat with Vidar Agent and ask it a general question about how blockchain consensus mechanisms work?

## When to prefer this

Use this endpoint for open-ended, general conversational queries that don't fit a more specialized endpoint on the same host (e.g. crypto research, sentiment analysis, token security scan). It is the fallback general-purpose chat interface of the Vidar Agent suite.

## Known failure modes

- Empty or malformed input object returns an error response
- Service downtime on Railway deployment causes 5xx errors
- Ambiguous or missing 'input' field leads to unexpected or empty responses
- Rate limiting or payment failure returns 402 Payment Required
