ASOS Scraper API in Python

Product search on ASOS — name, brand, price, was-price, colour, image. One POST from Python with query, rows back as JSON with 28 fields, $0.001 per delivered product. No proxies or parsers to maintain.

Get an API key See the collector

A Python requests snippet that posts { — A Python requests call to the asos_search collector returns one dict per product, at $0.001 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/asos_search/run",
    headers={"Authorization": f"Bearer {os.environ['QD_API_KEY']}"},
    json={
        "query": "dress",
        "max_results": 24,
    },
    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("product_id"), row.get("product_code"), row.get("name"), row.get("brand"))

Python: one ASOS search run (Vestiti), printing product_id, product_code, name, brand

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 ASOS search collector
Parameter	Type	Required	Meaning
`query`	string	yes	What to search, e.g. "dress".
`max_results`	integer	no (default 24)	How many products to deliver at most (1–300). You pay only for delivered products.

Response fields

28 fields per product.

Fields of each row (product)
Field	Type	What it holds
`rank`	integer	1-based position in ASOS's ordering for this response.
`product_id`	string	ASOS product id — the id that keys the /prd/ page.
`product_code`	string, nullable	ASOS internal product code (does not key the URL).
`name`	string	Product name.
`brand`	string, nullable	Brand name.
`colour`	string, nullable	Colourway as ASOS states it — its own casing is inconsistent ("PINK", "Chocolate").
`colour_way_id`	string, nullable	ASOS colourway id (the #colourWayId fragment on the URL).
`price`	number, nullable	Current price (USD).
`price_text`	string, nullable	Current price as ASOS formats it ("$52.00").
`original_price`	number, nullable	Struck-through was-price (USD); null when not reduced.
`rrp`	number, nullable	Recommended retail price (USD) when ASOS states one.
`currency`	string	Currency ASOS priced the row in — USD, from the US store the request pins. A run that comes back in anything else says so in the notes.
`discount_pct`	integer, nullable	Percent off the was-price; null unless both prices are stated.
`is_marked_down`	boolean	ASOS's own markdown flag.
`is_outlet`	boolean	Outlet pricing.
`is_selling_fast`	boolean	ASOS's low-stock badge.
`is_new`	boolean	ASOS's "New in" flag.
`is_sponsored`	boolean	Paid placement (ASOS keeps these out of the product list; false on every organic row).
`url`	string, nullable	Product URL.
`image`	string, nullable	Primary product image.
`images`	string[]	Gallery image URLs (main image first).
`video_url`	string, nullable	Catwalk video URL when the product has one.
`lowest_price_30d`	number, nullable	Lowest price in the last 30 days when ASOS states it.
`has_variant_colours`	boolean	True when the product page offers other colours.
`has_multiple_prices`	boolean	True when sizes or variants are priced differently.
`is_restocking_soon`	boolean	True when ASOS marks the product as restocking soon.
`is_promotion`	boolean	True when the product is in a promotion.
`other_colour_ids`	string[]	Product ids of the same style in other colours.

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/asos_search/run", headers=H,
                  json={**{"query":"dress","max_results":24}, "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

$0.001 per delivered product.

What ASOS search rows cost at list price
Rows	Cost
1	$0.001
1,000	$1.00
10,000	$10.00

Up to 300 products per run; split larger jobs into several runs. The $2 free credit every month covers about 2,000 products. No subscription; paid tiers lower the unit price. All collector prices: collector pricing.

Before you run it

Questions developers ask

Is there a free ASOS search API?

Every account gets $2 of free usage each month, about 2,000 products of this collector at $0.001 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 300 products 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. $0.001 per delivered product, no subscription.
