How this service works
Pay-per-call data endpoints for AI agents. USDC on Base via x402. No account, no API key — one micropayment per call.
Output
Returns a JSON object with: the original query string, a risk level (e.g. HIGH/LOW/MODERATE), flood zone details including SFHA boolean and FEMA zone code (e.g. AE), and a count of active weather alerts at the location.
Example use cases
Pre-purchase property flood check
“Before I make an offer on this house in Miami, FL, can you check if it's in a FEMA flood zone and what the overall site risk level is?”
Real estate listing risk disclosure
“I'm preparing a listing for a property in Houston, TX — can you pull the flood zone classification and risk level so I can include it in the disclosure?”
Mortgage underwriting site assessment
“We need to underwrite a loan for a property in New Orleans, LA — check whether it falls in a Special Flood Hazard Area and what the risk level comes back as.”
Technical details
Endpoint
GEThttps://api.polyform.org/v1/realestate/site-risk?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs a quick, pay-per-call flood zone and site risk verdict for a US real estate location without setting up accounts or API keys. Ideal for property due diligence, real estate listings, mortgage underwriting, or insurance pre-screening workflows where FEMA flood zone status and a summarized risk level are the primary outputs needed.
Side effects
- Location not recognized or ambiguous address returns an error or empty result
- Non-US locations may not be supported or may return incomplete data
- Network or payment failure (402 if micropayment not processed) blocks the response
- Rate limiting or transient upstream data source errors may cause occasional failures
