Redfin Scraper API in Python

Redfin properties for a US ZIP — price, beds, baths, sqft, MLS id, coordinates. One POST from Python with location, rows back as JSON with 42 fields, $0.0008 per delivered listing. No proxies or parsers to maintain.

A Python requests snippet that posts { — A Python requests call to the redfin_search collector returns one dict per listing, at $0.0008 each.

First call

Install, call, read the rows.

pip install requests

The only dependency.

import os, requests

r = requests.post(
    "https://api.quanticdata.io/v1/scraper/collectors/redfin_search/run",
    headers={"Authorization": f"Bearer {os.environ['QD_API_KEY']}"},
    json={
        "location": "78701",
        "max_results": 100,
    },
    timeout=120,
)
r.raise_for_status()
run = r.json()["payload"]
print(run["count"], "rows,", run["cost"]["usd"], "USD")
for row in run["results"]:
    print(row.get("mls_id"), row.get("address"), row.get("street"), row.get("city"))

Python: one Redfin listings run (Austin downtown), printing mls_id, address, street, city

The key comes from an environment variable, never from the code. The run answers in the same request when it finishes in time; payload.results holds the rows and payload.cost what they cost.

Request parameters

What the collector takes.

Input of the Redfin listings collector

`max_results`	integer	no (default 50)	How many listings to deliver at most (1–350). You pay only for delivered listings.

Add ?format=csv to the runs endpoint to get the same rows as CSV.

Long runs

Run in the background, then poll.

A run that needs more time can go to the background: send "async": true, get 202 with the run id, and poll the runs endpoint until the status is done. Reading a run is free.

import os, time, requests

H = {"Authorization": f"Bearer {os.environ['QD_API_KEY']}"}
r = requests.post("https://api.quanticdata.io/v1/scraper/collectors/redfin_search/run", headers=H,
                  json={**{"location":"78701","max_results":100}, "async": True}, timeout=30)
run_id = r.json()["payload"]["run_id"]
while True:
    run = requests.get(f"https://api.quanticdata.io/v1/scraper/collectors/runs/{run_id}", headers=H, timeout=30).json()["payload"]
    if run["status"] in ("done", "failed"):
        break
    time.sleep(5)
print(run["status"], run["count"])

Python: background run and polling

Errors

What can come back, and what is billed.

Collector run errors
Status	Meaning	Billed
`400`	The input does not match the collector (`payload.errors`)	No
`401`	Missing or wrong API key	No
`402`	Balance and free credit do not cover the run: top up	No
`422`	The input can never resolve; retrying the same input cannot help	No
`424`	The run failed at the source (blocked, timed out, layout changed); safe to retry	No
`429`	Rate limit or a per-account brake; wait for `Retry-After`	No

Only delivered rows are billed: a run that delivers nothing costs nothing.

Price

$0.0008 per delivered listing.

What Redfin listings rows cost at list price
Rows	Cost
1	$0.0008
1,000	$0.80
10,000	$8.00

Before you run it

Questions developers ask

Is there a free Redfin listings API?

Every account gets $2 of free usage each month, about 2,500 listings of this collector at $0.0008 each, with no card.

Do I have to handle proxies, retries or blocks?

No. The collector runs on our network and handles them; a run blocked at the source returns 424 and is not billed.

How many rows can one run return?

Up to 350 listings per run (the max_results input, where the collector has one).

Can an AI agent run it?

Yes: the MCP server exposes it as the run_collector tool, with the same input and price. See the MCP server.

Run it on the free credit.

Create an API key, export it as QD_API_KEY and run the example. $0.0008 per delivered listing, no subscription.
