If you came here because your RapidAPI Zillow integration suddenly started returning errors: you're not imagining it, and it's probably not your code. Sometime in 2026, the biggest Zillow-named listings on RapidAPI quietly disappeared. zillow56, zillow-com1, zillow-working-api, and real-time-zillow-data — for years the four defaults — all now return "API not found."
Nobody seems to have written this up, so here it is: what happened, where those publishers went, what every current listing actually costs (we verified each pricing page in a browser on August 19, 2026), and how to migrate if you got stranded. Full disclosure up front: APIllow runs one of the listings compared below, and we've kept our own row honest — including the parts where competitors beat us.
The great Zillow-name scrub
Here's the pattern. The dead slugs redirect to RapidAPI's "API not found" page, but the publisher accounts behind them are alive — several now run renamed listings with the same endpoint sets, newly carrying disclaimers like "Not affiliated with or endorsed by zillow.com… 'Zillow' is a trademark of its owner." That pattern — simultaneous renames plus fresh trademark disclaimers — looks like publishers responding to trademark pressure rather than a platform purge, especially since smaller listings still use "Zillow" in their names.
| Old listing (dead slug) | Status today | Where that publisher is now |
|---|---|---|
zillow56 |
"API not found" | No confirmed successor under the same account |
zillow-com1 (apimaker) |
"API not found" | Same publisher now lists US Housing Market Data — the classic endpoint set (propertyExtendedSearch, zestimate, priceAndTaxHistory, images…) intact |
zillow-working-api (ONEAPI) |
"API not found" | Same publisher now lists ZLLW Working API and private-zillow |
real-time-zillow-data (OpenWeb Ninja) |
"API not found" | Same publisher now lists Real-Time Real-Estate Data (their own site still markets it as "Real-Time Zillow Data API," with tier-for-tier matching prices) |
Practical consequence: tutorials, Stack Overflow answers, and no-code templates referencing those hosts (zillow56.p.rapidapi.com and friends) are now dead ends. If a guide tells you to subscribe to one of them, it predates the scrub.

Caveats that matter: prices and quotas change without notice — this is a snapshot from the pricing pages on August 19, 2026. "Service level" is RapidAPI's rolling metric, captured the same day. RapidAPI no longer shows subscriber counts anywhere, so ignore any article claiming them. And every listing rides on RapidAPI's platform bandwidth fee (10 GB/month included, then $0.001/MB) — heavier responses cost real money at volume.
Reading the numbers honestly
Three things the table can't show:
- A cheap request isn't a cheap result. Per-request pricing bills failures and empty responses too. What you care about is cost per successful property record with the fields you need. A $0.0013 request that's missing sold data is more expensive than it looks if you need sold data.
- Field coverage differs most on off-market homes. The sale date and full price history on off-market properties require enrichment beyond the listing page; most per-request scrapers skip it. If comps or valuations are your use case, test an off-market address on every provider's free tier before subscribing.
- Our latency looks worse than it is — by design. APIllow's listing shows higher median latency than per-request peers because it's an async batch API: you POST up to 1,000 properties, get a
job_id, and poll for results. One "request" can be a thousand properties, which is also why the request-count math differs. For single interactive lookups, a per-request API responds faster; for lists, batch wins on both cost and wall-clock.
Migrating a stranded integration
If you were on one of the dead listings, you have two paths:
Same-publisher successor. Re-subscribe to the renamed listing and update the host header — endpoint names largely survived (e.g. the old zillow-com1 endpoint set lives on under us-housing-market-data1.p.rapidapi.com). Fastest fix if the renamed API keeps working for you.
Or take the chance to fix the data gap. If you were living with missing sold dates and null price histories, migrate to the batch model instead. The old per-request pattern:
Addresses and Zillow URLs work as inputs too — no pre-resolving ZPIDs required. And if you'd rather skip the marketplace layer entirely, the direct API has the same plans without RapidAPI's bandwidth fee, plus an MCP server for AI-agent workflows.

Final takeaway
The RapidAPI Zillow ecosystem didn't die in 2026 — it renamed itself, and left a trail of broken integrations and stale tutorials behind. The listings that remain are genuinely comparable on price; the real differences are field coverage on off-market homes and request model. Test with free tiers, measure cost per successful result, and keep a copy of whatever host you subscribe to in your notes — apparently they can vanish.
