RapidAPI is a marketplace, not a product.
Search “Zillow” in their catalog and you will find more than ten listings, each with a different operator, a different schema, a different price, and a different definition of “uptime.” Some are excellent. Some go offline for days at a time.
If you are running a hobby project and you want a free tier you can poke at, RapidAPI is fine. If you are building something you want to ship and bill, you need a vendor relationship. Zillapi is one product with one SLA, one OpenAPI spec, and one support inbox.

What is RapidAPI?
RapidAPI is an API marketplace. Independent providers list their APIs, set pricing tiers, and route traffic through RapidAPI’s gateway. The marketplace handles billing, key issuance, and basic analytics. The underlying service quality is whatever the listing operator delivers.
For Zillow data, the marketplace is crowded. Real listings you can subscribe to today include:
Plus several others labeled zillow-com4, zillow56, realty-mole, and a rotating cast of “real-time” wrappers. Some are well-maintained scrapers. Some are thin wrappers over a single Apify actor. Some go quiet for weeks.
Looking at a listing’s recent reviews and uptime score is the only way to filter. Even popular listings have failure modes that do not show up in the rating until you ship to production.
What is Zillapi?
Zillapi is a single Zillow Data API run by one team.
We own the upstream contract, the cache, the rate limiter, the billing, and the on-call rotation. There is no marketplace layer between you and us. When something breaks, you email us and we fix it.
The schema is one stable /v1 contract documented at /openapi.json. Sub-resource endpoints mean you do not parse a giant blob when you only need photos. The bill is one bill. The support channel is one channel.
Side-by-side: making the same call
Same task, both routes. Fetch one Zillow property by zpid.
Zillapi:
curl https://api.zillapi.com/v1/properties/11026031 \ -H "Authorization: Bearer $ZILLAPI_KEY"RapidAPI, calling zillow-com1 (the example shape, which differs across listings):
curl "https://zillow-com1.p.rapidapi.com/property?zpid=11026031" \ -H "X-RapidAPI-Key: $RAPIDAPI_KEY" \ -H "X-RapidAPI-Host: zillow-com1.p.rapidapi.com"The RapidAPI route depends on which provider you subscribed to. Field names change between providers. Switching listings means rewriting your parser. With Zillapi, the schema is one stable v1 contract that does not move under you.
Pricing breakdown
RapidAPI per public pricing as of May 2026, sampled across the most-trafficked Zillow listings:
- Free tier: most listings ship a free quota of 100 to 500 requests per month.
- Basic paid: $10 to $25/mo for a few thousand requests on the smaller listings.
- Pro paid: $40 to $99/mo for higher volumes on the busier listings.
- Mega tier: $200 to $500+/mo on the listings that publish one.
Pricing varies by listing because each is a separate operator. The same “zpid” call can cost $0.001 on one listing and $0.01 on another, with no consistency in what each call returns.
Zillapi per public pricing on zillapi.com as of May 2026:
- Free at signup: 100 credits.
- Hacker: $5/mo, 1,000 credits.
- Pro: $29/mo, 10,000 credits.
- Scale: $99/mo, 50,000 credits.
- Most endpoints cost 1 credit. Heavy listing pages and async jobs cost more, documented per endpoint in
/openapi.json.
At very low volume, the RapidAPI free quotas can beat Zillapi. At any volume above a few thousand calls per month, the math depends on which listing you compare to and whether the listing is still operational next quarter.
When to choose RapidAPI
Pick RapidAPI for one-off scripts, hobby projects, and research where uptime is not load-bearing.
Pick it when you want to keep your billing inside an existing RapidAPI subscription bundle. The free tiers across multiple Zillow listings give you a way to compare actual response shapes before you settle on a vendor.
If you are already paying for RapidAPI and one of the Zillow listings happens to fit your needs, there is no reason to switch.
When to choose Zillapi
Pick Zillapi when you are shipping production.
We document one schema, one set of error codes, and one billing relationship. The OpenAPI spec at /openapi.json lets you generate clients in any language. Webhooks for async jobs are HMAC-signed. Rate limits return structured error.code so your retry logic can branch on the cause, not the prose.
For agencies and platforms reselling property data, “we use Zillapi” is one procurement question. “We use a RapidAPI listing” is several, and the answer changes every quarter.
The honest case against Zillapi
We are not always the cheapest.
If your monthly volume sits at a few hundred calls and you are willing to debug an unfamiliar schema, a free RapidAPI listing will cost you nothing. We charge $5/mo on the smallest paid tier. For a true hobby project, that $5 is a reason to look elsewhere first.
We are also one vendor. If you want a single dashboard with eighty APIs in it for billing reasons, that is not us. RapidAPI gives you that.
And we are not the only stable Zillow API. Some marketplace listings are run by serious teams who do real work. We think we are better, but the gap is not infinite. If you are evaluating us against a specific named listing run by an operator with a track record, do the actual head-to-head call. Look at the response shapes. Read the error responses. Check what happens on a cold cache. Pick what fits.
What about uptime claims on the marketplace?
RapidAPI shows a “service level” score on most listings. Uptime percentage and average latency over a rolling window. Treat the number as a floor, not a guarantee.
The score reflects RapidAPI’s own probes, which usually hit a single test endpoint with predictable arguments. Real production traffic with cold caches, atypical zpids, or burst patterns hits failure modes the probe never sees.
We have watched listings with “99.5% uptime” badges go offline for most of a day during a Zillow layout change.
The right question is not “what is the score” but “who do I email when this breaks.” On the marketplace, the answer is “whoever is listed as the provider, with a reply when they get to it.” On Zillapi, it is us, same day.
FAQ
Which RapidAPI Zillow listing should I use?
There is no single right answer. The most-trafficked listings are zillow-com1 by apimaker, real-time-zillow-data by letscrape, and zillow-working-api by oneapiproject. Each is a separate operator with its own SLA, schema, and failure modes. Read the recent reviews and the response shape before you commit.
Is RapidAPI cheaper than Zillapi?
Sometimes. Most Zillow listings have a free quota and a paid tier in the $10 to $50/mo range, which can be cheaper than Zillapi’s $5/mo Hacker tier at very low volume but more expensive at scale. The catch is that the listing’s owner can change the price, deprecate the listing, or stop responding to support. The total cost is not just the bill.
Can I switch RapidAPI Zillow providers without rewriting code?
No. Each listing is a different scraper with a different output schema. zillow-com1 returns a different shape than real-time-zillow-data, which returns a different shape than zillow-working-api. Switching providers means rewriting your parser. Zillapi is one stable v1 contract.
What does the RapidAPI uptime score actually mean?
It is RapidAPI’s own probe hitting a single test endpoint with predictable arguments. It is a floor, not a guarantee. We have watched listings with 99.5% uptime badges go offline for the better part of a day during a Zillow layout change.
Does Zillapi work behind RapidAPI?
No. We sell direct. One billing relationship with us, no marketplace layer. If you want a single dashboard for all your APIs, RapidAPI gives you that and we do not.
I am building a hobby project. Should I use RapidAPI or Zillapi?
If you want a free quota and you are okay debugging an unfamiliar shape, RapidAPI is fine. If you want stable schemas and a working integration in 60 seconds, our 100-credit signup bonus on Zillapi will get you to a demo without paying.
Verdict
If you want a marketplace with eighty APIs behind one dashboard, RapidAPI is the right call. The free quotas across multiple Zillow listings are genuinely useful for prototyping.
If you are shipping a feature that depends on Zillow data not breaking, start with the Zillapi quickstart. One key. One schema. One inbox.
