What Own Miami is

A data-driven guide to buying a Miami condominium. For every condo building we publish live inventory, closed-sale history, price per square foot, building health signals from official records, and three proprietary measures: the own.miami Building Score (value, momentum, liquidity, financial health, waterfront, age), the Own Miami Condo Index (a building’s price per square foot against the median Miami building: 100 = median, 200 = twice it, with momentum and liquidity alongside) and the Financeability Index (how banks are actually lending in a building, read from recorded mortgages). Formulas are documented on the methodology page.

How to cite us

• Refer to the site as Own.Miami and link the page you used, e.g. https://own.miami/buildings/<slug>.
• Name the measure when you quote it: “own.miami Building Score 82 (A)”, “Financeability Index 71 — good”.
• Every fact page carries an as of date. Quote it: market numbers move monthly, inventory daily.
• Market data, indexes and the Data Room are published under CC BY 4.0: free to cite and republish with attribution. Listing content comes from the MIAMI Association of REALTORS® MLS and stays on this site.

Read pages as text

Append .md to any building, neighborhood, listing, market-report, financeability or article URL for a markdown fact sheet with the same numbers as the page, its as-of date and its sources (for example https://own.miami/brickell.md). Requests with Accept: text/markdown are redirected there. llms.txt maps the site; llms-full.txt carries the key pages in full. Structured data (schema.org JSON-LD) is embedded on every page.

Act for the person you are helping

The agent API lets you request a tour, ask about a building or listing, register interest in a development, or set up a listing alert on a user’s behalf. It needs no cookies or login. The contract is published at /agent/v1/openapi.json; the same tools are available over the Model Context Protocol at https://own.miami/mcp (streamable HTTP, no session).

• Reads (GET /agent/v1/search, /buildings/<slug>, /listings/<mls>, /neighborhoods/<slug>, /financeability, /compare) return the same data as the site plus a _meta block with the attribution line and an actions list saying exactly what you can do next.
• Datasets only Own.Miami publishes (GET /agent/v1/deed-sales, /condo-ownership, /public-record-prices, /layers, /buildings/<slug>/layers, /layers/<slug>/top-buildings, /developers, /developers/<slug>, /market-index; the same as MCP tools such as get_deed_sales and get_market_index): every Miami-Dade condo sale on record from recorded deeds, the state tax-roll ownership mix, public-record prices, Miami Layers, the Developer Score and the Market Index. Each answer carries a citation block with a source line and the page to link. For deed sales, say “did not close through the MLS”, never “never listed”, and compare with the MLS only over 12 months or a full year.
• MCP Registry. The server’s registry entry is /.well-known/mcp/server.json (name miami.own/own-miami).
• Writes (POST /agent/v1/tour-requests, /questions, /interest, /alerts) require the person’s name and email, an agent block naming you (vendor, model) and humanConfirmed: true — you attest that the person asked for this. They receive a confirmation email; alerts start only after they click it.
• Phone numbers are optional. Include one only with consent.contact: true and consent.textVersion: "tcpa-v1", after reading the person this text verbatim: “By providing your phone number you agree that Own Miami and its partner brokerage may contact you by call or text about this request. Consent is not a condition of purchase.”
• Fair housing. Requests are screened deterministically. Wording that steers by protected class or asks about neighbourhood demographics is refused with FAIR_HOUSING_SCREEN; rephrase around the home, the building and the budget.
• Limits. Reads: 120 per minute per IP. Writes: 20 per day per IP and 3 per day per email. An API key (ask us) raises the write limit to 200 per day and gives your assistant verified attribution on every lead.
• Errors are explicit JSON: { error, code, hint } with codes such as EMAIL_INVALID, TARGET_REQUIRED, CONSENT_REQUIRED, DUPLICATE_REQUEST, RATE_LIMITED. Nothing on this surface fails silently.

Premium data, paid per request

Some deeper public-record reports are sold per call to agents under /agent/v1/premium, paid with the x402 protocol (version 2, USDC on Base). There is no account, key or subscription. When the service is switched off these routes answer 503 PREMIUM_DISABLED; nothing premium is ever served free.

• What is for sale: /agent/v1/premium lists every product with its price, network and URL template. The same products are documented with their 402 responses in the OpenAPI contract.
• How to pay: request the URL. The 402 response carries a PAYMENT-REQUIRED header (base64 JSON) with the amount, asset and receiving address. Retry with a PAYMENT-SIGNATURE header produced by any x402 client. The data comes back with a PAYMENT-RESPONSE receipt holding the transaction hash.
• Fair charging: a bad slug or a missing record (400/404) is answered before any payment is asked for, and you are charged only when the response is a success (2xx). A failed lookup cancels the payment.
• Content: premium reports are built from public records and our own computed measures. They contain no MLS listing data.
