Example prompt: Pull market intelligence from The Stall on IntuiTek for the commercial real estate segment — I'll pay the 0.5 USDC per-call fee on Base mainnet, no API key needed.

## When to prefer this

Choose this endpoint when you need on-demand market intelligence without committing to a subscription or API key, and you are able to pay 0.5 USDC per call on Base mainnet via the x402 protocol. Ideal for agents with crypto payment capability needing occasional market data lookups.

## Known failure modes

- Payment not received or insufficient USDC — returns 402 Payment Required
- Invalid or missing properties parameter — returns 400 Bad Request
- Service temporarily unavailable — returns 503
- Network congestion on Base mainnet delays payment confirmation
- Malformed query string results in empty or error response

## How this service works

Returns settlement-verified x402 endpoint intelligence. Shows which endpoints have genuine organic payer breadth and live pricing — sourced from on-chain USDC settlements, not just catalog listings. Filter by category, price range, and minimum unique payers. Useful before wiring a workflow to an external x402 endpoint: confirms it is active with multiple independent payers, not private infrastructure or a dead listing.

## Output

Returns structured market intelligence data for the queried properties or segment, delivered as a JSON payload after USDC payment is confirmed on Base mainnet.
