G2 Scraper API in Python

Software products and service providers from a G2 search — rating, review count, vendor and categories. One POST from Python with query, rows back as JSON with 15 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 g2_products 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/g2_products/run",
    headers={"Authorization": f"Bearer {os.environ['QD_API_KEY']}"},
    json={
        "query": "crm",
        "max_results": 40,
    },
    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_uuid"), row.get("name"), row.get("type"))

Python: one G2 software search run (CRM software on G2), printing product_id, product_uuid, name, type

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 G2 software search collector
Parameter	Type	Required	Meaning
`query`	string	yes	What to search G2 for, e.g. "crm", "help desk" or "salesforce consulting". Matches products and service providers alike.
`country`	string	no	ISO 3166-1 alpha-2 code — proxy exit geo and Google locale (gl). Omit for the default pool.
`max_results`	integer	no (default 20)	How many products to deliver at most (1–300). You pay only for delivered products.

Response fields

15 fields per product.

Fields of each row (product)
Field	Type	What it holds
`rank`	integer	Position in G2's order for this response, counting across pages.
`product_id`	integer, nullable	G2's numeric product id — stable, and the key used to de-duplicate.
`product_uuid`	string, nullable	G2's internal product UUID, when the row carries one.
`name`	string	Product or provider name.
`type`	string, nullable	What G2 classes the row as: "Software" for a product, "Provider" for a services firm.
`rating`	number, nullable	Average star rating out of 5. Null when G2 states no score — it prints "0/5" as a placeholder, and that is never delivered as a rating of zero.
`reviews`	integer, nullable	Number of reviews as G2 states it. 0 is a real value and is kept.
`vendor`	string, nullable	Seller/vendor name as linked on the row.
`vendor_id`	integer, nullable	G2's numeric vendor id.
`vendor_url`	string, nullable	G2 seller page URL.
`description`	string, nullable	The product description G2 shows on the result card.
`categories`	string[], nullable	Related G2 categories for this product (1 to ~37 per row, read per card).
`logo`	string, nullable	Product logo image URL.
`slug`	string, nullable	G2 URL slug for the product.
`url`	string, nullable	G2 product page URL.

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/g2_products/run", headers=H,
                  json={**{"query":"crm","max_results":40}, "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 G2 software 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 G2 software 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.
