## 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 streetwear-sneaker-market-data-procurement-decision-brief-71c77ce0
```

Example prompt: Give me a blunt decision procedure for when my resale agent should pay for aggregated StockX or GOAT-style pricing and sales history versus just scraping public product pages — I need the per-SKU spend caps, freshness gates, and margin rules laid out clearly.

## When to prefer this

Use this endpoint when an autonomous agent needs a structured, opinionated decision framework for streetwear and sneaker market data procurement — specifically when you want pre-built rules covering spend caps, freshness gates, source verification, and margin logic, rather than building that logic yourself. Prefer it over generic market data endpoints when the domain is specifically resale sneakers/streetwear and you need agent-executable decision procedures rather than raw price data.

## Known failure modes

- Payment not included or invalid — returns 402 with payment required detail
- Invalid method (POST/PUT) — only GET/HEAD/DELETE accepted
- Malformed queryParams — topic must be a string, meta must be '0' or '1'
- LLM generation failure — ok:false with no brief returned
- Network timeout on the ascii.dev host — no response or connection error
