## 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 agent-newsstand-full-trading-context-for-tokenized-asset-f27f735e
```

Example prompt: Pull the full trading context for xyz:TSLA covering the last 30 days — I want price data, macro signals, news, and anything else relevant to trading it right now.

## When to prefer this

Choose this endpoint when you need a comprehensive, all-in-one trading context bundle for a tokenized asset rather than fetching individual data points (candles, SEC filings, macro data) separately. It is ideal for agents that need to make or explain trading decisions and want a single call to get everything relevant. Prefer this over sibling endpoints like candles-only or SEC-filings-only when breadth of context matters more than depth on a single dimension.

## Known failure modes

- Missing required 'symbol' parameter — returns 400 or validation error
- Invalid symbol format (e.g. missing venue prefix like 'xyz:') — returns error or empty result
- 'days' out of range (must be 1-90) — returns validation error
- Symbol not found or unsupported token — returns 404 or empty context
- Payment not processed or x402 payment failure — returns 402 Payment Required
- Upstream data source unavailable — may return partial context or 503
