## 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 obol-stack-bankr-token-analyst-chat-completions-8bed3154 -d '<json body>'
```

Example prompt: Can you analyze the fundamentals and recent performance of the $ARB token for me — is it a good buy right now? Use the Bankr token analyst and give me a detailed breakdown.

## When to prefer this

Choose this endpoint when you need AI-powered analysis or Q&A specifically about crypto tokens, DeFi projects, or blockchain assets, and you want to pay per call with USDC rather than managing a subscription. Prefer it over generic LLM endpoints when the task is token/crypto research and you want a purpose-scoped analyst persona.

## Known failure modes

- Malformed messages array — missing required role or content fields
- Rate limit or quota exceeded on the underlying OpenRouter model
