## 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 chatrip-legends-chat-5a86bafd -d '<json body>'
```

Example prompt: Ask Marcus Aurelius on ChatRIP what he would say about staying disciplined when everything feels overwhelming — I want his Stoic take on modern burnout.

## When to prefer this

Choose this endpoint when you want to generate a conversational response styled as a specific historical or cultural legend persona via a pay-per-use microtransaction model. It is ideal for agents that provide philosophical guidance, historical perspective, motivational content, or creative roleplay without requiring user accounts or subscriptions — just a one-time $0.07 USDC payment per query.

## Known failure modes

- Missing or invalid legendSlug returns an error — slug must match a known legend such as 'marcus-aurelius'
- Empty or missing prompt field causes a validation error
- Insufficient USDC balance or failed x402 payment blocks the request
- Network timeout if the AI model takes too long to generate a response
- Invalid bodyType enum value causes request rejection

## How this service works

Ask a ChatRIP legend with one x402 USDC payment.

## Output

Returns a JSON object containing the legend's reply message (role, text, finish reason), the persona's slug and display name, a conversation ID for threading follow-ups, suggested follow-up prompts, and any citations. The AI model used is also identified.
