Terms of Service

Last updated 22 October 2026

These terms are an agreement between you and PropertiesAPI ("PropertiesAPI", "we", "us"), the service at propertiesapi.com and api.propertiesapi.com. They are short on purpose. Please read them before you create an account or send a request.

1. Acceptance and eligibility

• By creating an account, using an API key or using the demo, you accept these terms, the Acceptable Use Policy and the Privacy Policy.
• You must be at least 18 years old and able to enter into a binding agreement.
• If you sign up for a company or other organisation, you confirm you have authority to accept these terms for it, and "you" then means that organisation.

2. The Service

PropertiesAPI (the "Service") returns property data read from public Zillow property pages, as JSON, for a Zillow link, an address or a property ID. Lookups are made when you ask, through third-party data-collection providers we choose. You can reach the Service through:

• the REST API, for single lookups and batch requests;
• the MCP server, for AI assistants and agents;
• Google Sheets formulas and CSV bulk upload;
• watchlists with webhooks; and
• our SDKs.

Some of these may be marked as coming soon on the site. These terms apply to each of them once it is available. We may add, change or retire features, fields and endpoints, and we'll try to give notice of breaking changes to documented fields.

3. Plans, billing and the free tier

Plans, prices and included lookups are listed on the pricing page. Paid plans follow these rules:

• Free. A Free account comes with 50 free lookups, once. They don't renew each month.
• Monthly plans. Each paid plan includes a number of lookups per billing period. Past them, each successful lookup costs your plan's rate per 1,000 lookups, shown on each plan. No cap on usage: after your included lookups, each lookup is billed at your plan's rate. Optionally set a monthly limit.
• No rollover. A plan's included lookups belong to its billing period. Any you don't use expire when the period ends.
• Pay as you go. Prepaid packs are one-time purchases, not a subscription. Credits last 12 months from the purchase. On a plan, they are used after its included lookups and before any usage past them.
• Only successful lookups are billed. Failed lookups and properties that aren't found cost nothing. Repeat lookups of the same home within 24 hours come from our cache and are free.
• Renewal and cancellation. Paid plans renew monthly until you cancel. You can cancel at any time from your dashboard, and the plan runs to the end of the period you paid for.
• Price changes. We may change prices for future periods with at least 30 days' notice by email.
• Refunds. Fees are non-refundable, except where the law requires a refund or we decide to give one.
• Refunds and disputes of a pack. If a pack's payment is refunded or disputed, the pack's unused credits are removed.
• Refunds and disputes of a plan. If a plan charge is refunded in full or disputed, the plan's lookups are suspended. Prepaid credits you bought separately stay usable.

4. Data is provided as-is

• All data is provided as-is and as available. We return what a public page shows at the time of the lookup, and we don't check it against other sources.
• Which fields come back varies by listing. A field the page doesn't show comes back as null.
• Zestimates are Zillow's estimates, returned as Zillow shows them. Fields marked as calculated in the docs are simple arithmetic by PropertiesAPI on the fields in the same response.
• We make no promise that the data is accurate, complete or current, or that the Service is available at any particular time. Lookups can be slow or fail.
• Check anything that matters against an independent source before you rely on it.

5. Not professional advice

• Nothing from the Service is an appraisal, or legal, tax, financial or investment advice. Prices, Zestimates and calculated fields are not valuations you can rely on for a transaction or a loan.
• PropertiesAPI is not a consumer reporting agency, and its data is not a consumer report under the Fair Credit Reporting Act (FCRA). Don't use it for tenant, credit, employment or insurance screening.

6. No affiliation with Zillow

PropertiesAPI is an independent service and is not affiliated with, endorsed by or sponsored by Zillow. The data isn't official and isn't licensed from Zillow. Zillow, Zestimate and other names are used only to identify the source of the data and belong to their owners.

7. Acceptable use and rate limits

Your use must follow the Acceptable Use Policy. In short:

• Keep your API keys secret. Use them from your server, not from a browser or a public repository. Anything done with your key is your responsibility until you revoke it. Keys are stored in hashed form and shown only once, when you create them.
• Stay within the request limits. Free accounts: 60 requests a minute and up to 25 live lookups a day (UTC); lookups paid from prepaid credits don't count toward it. Cache hits are free and don't count as live lookups. Paid plans: 120 requests a minute on Starter, 300 on Pro, 600 on Business and 1,200 on Scale. The per-minute limit is per account: all its keys and batch items count together.
• Don't open several Free accounts, or use any other trick, to get around limits, quotas or billing.
• Don't share or resell your keys, and don't resell or redistribute the raw data as a competing data feed or API.
• Don't use the Service unlawfully, including against fair housing laws, the FCRA or anti-spam and do-not-call laws.
• Don't use the Service in a way that infringes anyone else's rights, including copyright in listing photos and other content.

8. Intellectual property

• The Service, the website, the documentation and our software belong to PropertiesAPI. Our SDKs are released under their own open-source licence (MIT), which applies to that code.
• We don't own the property data, and we can't grant you any rights in Zillow's content or in listing photos. Photos are returned as links, and their copyright usually belongs to the photographer or the listing broker. Whether you may store, display or republish any data is your responsibility.
• Your inputs and your results are yours to use within these terms. If you send us feedback, we may use it without owing you anything.

9. Limitation of liability

To the extent the law allows:

• the Service is provided without warranties of any kind, express or implied, including fitness for a particular purpose;
• we aren't liable for indirect, incidental, special or consequential damages, or for lost profits, revenue or data; and
• our total liability for all claims is limited to the greater of the fees you paid us in the 3 months before the claim, or USD 100.

10. Indemnification

If a third party makes a claim against us because of how you used the Service or its data, or because you broke these terms or the law, you agree to cover our reasonable losses and costs, including legal fees, arising from that claim.

11. Suspension and termination

• We may suspend or close an account, or revoke a key, if it breaks these terms or the Acceptable Use Policy, puts the Service or other people at risk, or if the law requires it.
• You can stop using the Service at any time, cancel your plan, and ask us to close your account.
• The sections on data, advice, intellectual property, liability, indemnification and governing law still apply after an account is closed.

12. Changes to these terms

We may update these terms. The date at the top shows the latest version. If a change is material, we'll email account holders before it takes effect. Using the Service after that means you accept the new terms.

13. Governing law and severability

• These terms don't choose a particular governing law or court. Any dispute is decided under the law, and in the forum, that applies to it by the ordinary rules, and nothing here takes away consumer rights you have where you live.
• If any part of these terms can't be enforced, the rest still applies.
• If we don't enforce a term straight away, we haven't given up the right to enforce it later.
