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 containing a posture field (e.g. 'STANDARD') representing the underwriting risk classification for the queried real estate subject. The posture value categorizes the deal's risk profile as assessed by Polyform's model.
Example use cases
Quick deal risk screen for investor
“Can you run an underwriting posture check on this property before I proceed? I don't want to set up an account anywhere — just get me the risk classification instantly.”
Automated pipeline underwriting gate
“For each property deal coming through our pipeline, call the Polyform underwriting endpoint and tell me which ones come back as anything other than STANDARD posture so I can flag them for review.”
Single property pre-qualification check
“I'm about to make an offer on a property — can you run a quick underwriting assessment via Polyform and tell me what risk posture it returns before I commit?”
