Example prompt: Can you pull the federal housing data for Windsor from Script Master Labs — it costs a fraction of a cent per call and settles in USDC on Base via x402.

## When to prefer this

Choose this endpoint when you need U.S. federal housing data specifically for Windsor and want micro-cost pay-per-call billing settled in USDC on Base via x402 — ideal for AI agents that handle payment autonomously. Prefer this over subscription APIs when making infrequent or one-off lookups where paying $0.001 per call is more economical than a monthly plan.

## Known failure modes

- Payment not settled — x402 USDC payment on Base failed or was not included, returning a 402 Payment Required response
- Invalid or missing query parameters result in empty or error response
- Windsor-specific data not available in the federal dataset returns empty example object
- Rate limiting or server unavailability on Render hosting causes timeouts
- Malformed request schema returns a generic error

## How this service works

Pay-per-call crypto, RWA, federal, SEC, Section 8/HUD housing, and compliance APIs via x402. Primary: USDC on Base (eip155:8453). Also accepts Global Dollar (USDG) on Robinhood Chain (eip155:4663) via sovereign X-PAYMENT-TX. Hyphen routes only (e.g. /x402/gas-tracker, /x402/pha-lookup, /x402/sec-8k). MARKETPLACE REVIEW: use free /x402/playground/* (no key, no payment). Production /x402/* returns 402 unless paid via x402 or X-Api-Market-Key / X-API-Key from seller dashboard.

## Output

Returns a JSON object containing U.S. federal housing data specific to Windsor, which may include housing unit counts, affordability metrics, occupancy rates, or other HUD-sourced statistics. The exact schema is not fully documented but follows the federal data format for housing records.
