Real estate deal memo API

One US street address in. Owner, automated value estimate, long-term rent estimate, comps, cap rate, cash-on-cash, DSCR, red flags and a one-paragraph memo out. Deterministic underwriting over RentCast data, built for AI agents: MCP server, Apify Actor and a plain HTTP endpoint that answers 402 with payment options.

Try it free (no key)

curl "https://agentwares-deal-memo.vercel.app/api/v1/memo?sample=true&address=1547%20Example%20Ave%2C%20Cleveland%2C%20OH%2044109"

sample=true returns a realistic recorded example (1547 Example Ave, Cleveland, OH 44109) at no charge and never calls a model. It ignores the address you pass.

Paid call ($ 0.75 per memo, $0.1 per lookup)

curl -X POST https://agentwares-deal-memo.vercel.app/api/v1/memo \
  -H "Authorization: Bearer $DEAL_MEMO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"address":"<full US address>","strategy":"rental","assumptions":{"down_payment_pct":0.2}}'

Without a key the same request returns 402 Payment Required with x402 and Stripe MPP requirements in the headers and body (pay-per-call goes live with the wallet).
