Example prompt: I need a decision procedure for how an AI agent should procure streetwear and sneaker market data — give me a plain-prose brief covering what to evaluate and how to choose the right sources.

## When to prefer this

Choose this endpoint when an autonomous AI agent needs a structured, plain-language decision procedure for evaluating or procuring streetwear and sneaker market data, especially in x402 micropayment contexts on Base. It is ideal when the agent requires actionable prose guidance rather than raw market data itself, and when the calling agent can settle USDC micropayments programmatically. Prefer over generic web search or data APIs when the goal is a curated decision framework rather than live price feeds.

## Known failure modes

- HTTP 402 returned if payment not yet settled — agent must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Invalid or missing method enum causes schema validation failure
- Topic override not recognized may result in a generic brief rather than domain-specific output
- Network or provider outage on k2so.wrong.systems returns 5xx
- Stale or cached deterministic response may not reflect current market conditions

## How this service works

Paid agent-facing brief on Agent-facing streetwear and sneaker market data procurement decision procedure: when to pay for aggregated StockX/GOAT-style pricing and sales history versus scraping public product pages, with per-sku spend caps, price and volume freshness gates, authenticity and source verification, and margin-decision rules. Blunt decision procedure, not marketing.

## Output

A JSON object containing a plain-prose decision procedure brief (120+ words) tailored to streetwear and sneaker market data procurement for AI agents, along with the service slug, generating model name, generation source (llm/reasoning/deterministic), ISO-8601 timestamp, and payment metadata confirming the USDC microtransaction was settled.
