eBay Proxies for Scraping eBay in 2026 with Stable Results

If your eBay scraping keeps hitting 403, captchas, missing price or variants, or slow runs, it’s usually caused by one of four things: request pace is too aggressive, rotation is too jumpy, exits are mismatched to the task, or you’re parsing a challenge page instead of real content. Start with a small benchmark, lock a steady cadence, rotate on a schedule, and validate field completeness for every page type.

The shortest working route

1. Confirm you’re only scraping public pages and not stepping into login walls or personal data.
2. Benchmark 20–50 URLs across product, search, category, and seller pages.
3. Choose proxy type based on the job (stable monitoring vs bulk discovery).
4. Start slow per exit and scale only when block rate stays low.
5. Troubleshoot in a fixed order: rate → headers → exit quality → parsing.

If you’re setting up a proxy plan specifically for eBay, this overview of eBay Proxies aligns well with how the page types behave in practice.

Decide what to scrape on eBay so the data is actually usable

Treat eBay as four different scraping tasks. Each one needs slightly different pacing and validation.

• Product pages: title, current price, shipping, condition, and variant logic
• Search results: discovery at scale, pagination, URL harvesting, ranking order
• Category pages: broad inventory coverage, more stable “feed-like” discovery
• Seller pages: seller-level summaries and inventory sampling without personal detail collection

Before you scale anything, confirm you’re not scraping restricted areas. A quick reference for how robots rules work is the robots standard explanation at robotstxt.org.

Next step: list the fields you truly need for your use case (price monitoring, inventory discovery, competitor tracking) and remove anything you do not need.

Choose proxies without wasting money by matching the task

Buying proxies is a decision problem, not a feature checklist. “More IPs” won’t fix a bad rhythm, and “fast rotation” often increases captchas.

Proxy type comparison for scraping eBay

For beginners who want stable completion rates on product pages, many teams start with a residential pool such as Residential Proxies and only scale after the benchmark proves the cadence is safe. MaskProxy users typically get the best consistency when they rotate less often than they think they need to.

Rules that work in real runs

• Per-exit pace: begin at 1 request every 2–5 seconds per exit
• Concurrency per exit: keep it at 1–2 until blocks are near zero
• Rotation: rotate on schedule, not randomly
• Region: keep exits aligned to the market you’re scraping to avoid price/shipping inconsistencies

Next step: pick one proxy type and run a 200-request benchmark before you buy more capacity.

Understand why 403 and 429 are not random events

When your scraper “suddenly” starts failing, it’s usually because you changed traffic shape: faster cadence, higher concurrency, noisier rotation, or mixed regions.

Use these as your quick meaning checks:

• 403 meaning: HTTP 403 Forbidden
• 429 meaning: HTTP 429 Too Many Requests

Practical interpretation:

• 429 rising usually means “slow down and respect Retry-After.”
• 403 rising usually means “reduce traffic shape risk and stabilize exits,” not “retry harder.”

Next step: start logging status code, latency, proxy ID, and whether key fields were present. Debugging without these numbers is guesswork.

Use a simple scraping architecture that stays stable when you scale

Here’s the smallest architecture that still behaves like a real system.

flowchart LR
  A[URL inputs product search category seller] --> B[Queue with dedupe and priority]
  B --> C[Fetcher proxies rate limit retries]
  C --> D[Parser HTML and embedded scripts]
  D --> E[Cleaner normalize validate completeness]
  E --> F[Exporter CSV JSON DB]
  C --> G[Logs status latency proxy attempts]
  G --> H[Metrics success rate block rate cost]
  H --> B

Next step: decide the “key fields” for each page type and treat missing key fields as a failure that needs a controlled second attempt.

Quick Start for a minimal working scraper in minutes

This quick start is intentionally small: fetch HTML, parse a few fields, and keep it stable. It uses httpx because proxy handling and timeouts are straightforward.

Install

pip install httpx lxml beautifulsoup4 pandas

Minimal product page fetch and parse

import httpx
from bs4 import BeautifulSoup

def fetch_html(url: str, proxy: str | None = None, timeout=20) -> str:
    headers = {
        "User-Agent": "Mozilla/5.0",
        "Accept-Language": "en-US,en;q=0.9",
        "Accept": "text/html,application/xhtml+xml",
    }
    with httpx.Client(
        proxies=proxy,
        headers=headers,
        timeout=timeout,
        follow_redirects=True
    ) as client:
        r = client.get(url)
        r.raise_for_status()
        return r.text

def parse_product_basic(html: str) -> dict:
    soup = BeautifulSoup(html, "lxml")
    title = soup.select_one("h1")
    price = soup.select_one('[itemprop="price"], .x-price-primary span')
    condition = soup.select_one(".x-item-condition-text span")
    return {
        "title": title.get_text(strip=True) if title else None,
        "price": (price.get("content") if price and price.has_attr("content") else (price.get_text(strip=True) if price else None)),
        "condition": condition.get_text(strip=True) if condition else None,
    }

if __name__ == "__main__":
    url = "https://www.ebay.com/itm/176212861437"
    proxy = None  # e.g. "http://user:pass@host:port"
    html = fetch_html(url, proxy=proxy)
    print(parse_product_basic(html))

Next step: run this on 10 product URLs and note how often price and condition are missing. If missing fields are common, you’ll solve that in the product-page section before scaling.

Scrape product, search, category, and seller pages with a repeatable workflow

Product pages: prevent missing price and variants

Missing price or variants often happens because the values live in embedded scripts, not the visible HTML. Treat it as a data placement problem first.

Workflow

1. Parse visible HTML for basic fields.
2. Validate completeness.
3. If incomplete, extract embedded JSON or script data.
4. Only use Playwright if data is truly rendered after load.

Here is a safe pattern: if key fields are missing, mark the row incomplete, then attempt a script extraction pass.

import re, json

def extract_embedded_json_candidates(html: str) -> list[dict]:
    # Heuristic: find JSON-like blocks in scripts and try decoding a few candidates.
    candidates = []
    for m in re.finditer(r"<script[^>]*>(.*?)</script>", html, flags=re.S | re.I):
        s = m.group(1).strip()
        if len(s) < 200:
            continue
        # Look for obvious JSON objects
        if "{" in s and "}" in s:
            # Try to locate a JSON object substring
            j = re.search(r"(\{.*\})", s, flags=re.S)
            if not j:
                continue
            chunk = j.group(1)
            try:
                candidates.append(json.loads(chunk))
            except Exception:
                pass
    return candidates

def completeness_score(row: dict, required: list[str]) -> int:
    present = sum(1 for k in required if row.get(k))
    return int((present / max(1, len(required))) * 100)

Next step: define a required field list for product pages like ["title", "price", "condition"] and store completeness score. It makes “data quality” measurable.

Search pages: pagination, dedupe, and checkpointing

Search pages are where you gather item URLs safely and repeatedly.

Workflow

• Fetch page 1
• Extract item links
• Dedupe
• Save a progress checkpoint
• Continue to the next page

import json
import httpx
from bs4 import BeautifulSoup
from pathlib import Path

PROGRESS = Path("search_progress.json")

def load_progress():
    if PROGRESS.exists():
        return json.loads(PROGRESS.read_text("utf-8"))
    return {"page": 1, "seen": []}

def save_progress(state):
    PROGRESS.write_text(json.dumps(state, ensure_ascii=False, indent=2), "utf-8")

def search_page_links(keyword: str, page: int, proxy: str | None = None) -> list[str]:
    base = "https://www.ebay.com/sch/i.html"
    params = {"_nkw": keyword, "_pgn": page}
    headers = {"User-Agent": "Mozilla/5.0", "Accept-Language": "en-US,en;q=0.9"}
    with httpx.Client(proxies=proxy, headers=headers, timeout=25, follow_redirects=True) as client:
        r = client.get(base, params=params)
        r.raise_for_status()
    soup = BeautifulSoup(r.text, "lxml")
    out = []
    for a in soup.select("a.s-item__link"):
        href = a.get("href")
        if href and "/itm/" in href:
            out.append(href.split("?")[0])
    return out

def dedupe_urls(urls: list[str], seen: set[str]) -> list[str]:
    out = []
    for u in urls:
        if u not in seen:
            out.append(u)
            seen.add(u)
    return out

Next step: stop when a page produces almost no new URLs after dedupe. That’s a natural stability limit for discovery runs.

Category pages: use them as stable inventory feeds

Category pages behave like “curated search.” They’re useful when keyword search results are noisy.

Approach:

• Treat category pages as URL sources.
• Extract item URLs the same way.
• Keep pacing conservative because category pages are often heavily crawled.

Next step: run category discovery with a slower cadence than search runs, and rotate less frequently to reduce “jumpy” behavior.

Seller pages: collect summary metrics without crossing lines

Seller pages are best for summary-level monitoring:

• feedback score summary
• listing count
• store inventory sampling

Avoid collecting identifying personal details. If your use case can be covered by official APIs, check the entry point at eBay Developers Program.

Next step: keep seller scraping to summary fields and listing URLs only, and drop anything you don’t need for analysis.

Build a production version with retries, backoff, caching, concurrency, and logs

Production stability is mainly about what you do when things fail.

Backoff decision flow

flowchart TD
  A[Request URL] --> B{Status code}
  B -->|200| C[Parse and validate]
  C -->|Complete| D[Write output]
  C -->|Incomplete| E[Mark incomplete and attempt script extraction]
  B -->|429| F[Read Retry-After or apply exponential backoff]
  F --> G[Lower rate and concurrency]
  G --> A
  B -->|403| H[Slow down switch exit check headers]
  H --> I{Still blocked}
  I -->|Yes| J[Pause reduce scope or use API coverage]
  I -->|No| A
  B -->|Captcha page| K[Stop forcing stabilize exits reduce rotation]
  K --> A

Before you scale, make sure your proxy strings and schemes are consistent across your team. This reference is useful for keeping formats correct: Proxy Protocols.

Production fetcher with cache and smarter retry

import time, json, hashlib
import httpx
from pathlib import Path

CACHE_DIR = Path("./cache")
CACHE_DIR.mkdir(exist_ok=True)

def cache_key(url: str) -> str:
    return hashlib.md5(url.encode("utf-8")).hexdigest()

def load_cache(url: str) -> str | None:
    p = CACHE_DIR / f"{cache_key(url)}.html"
    return p.read_text(encoding="utf-8") if p.exists() else None

def save_cache(url: str, html: str) -> None:
    p = CACHE_DIR / f"{cache_key(url)}.html"
    p.write_text(html, encoding="utf-8")

def fetch_with_retry(url: str, proxy: str | None, max_attempts=4, base_sleep=2.0):
    headers = {
        "User-Agent": "Mozilla/5.0",
        "Accept-Language": "en-US,en;q=0.9",
        "Accept": "text/html,application/xhtml+xml",
    }

    cached = load_cache(url)
    if cached:
        return 200, cached

    with httpx.Client(proxies=proxy, headers=headers, timeout=25, follow_redirects=True) as client:
        last_status = 0
        for attempt in range(1, max_attempts + 1):
            t0 = time.time()
            r = client.get(url)
            latency_ms = int((time.time() - t0) * 1000)
            status = r.status_code
            last_status = status

            print(json.dumps({
                "url": url,
                "status": status,
                "latency_ms": latency_ms,
                "attempt": attempt,
                "proxy": proxy or "DIRECT",
            }, ensure_ascii=False))

            if status == 200:
                save_cache(url, r.text)
                return status, r.text

            if status == 429:
                ra = r.headers.get("Retry-After")
                sleep_s = float(ra) if (ra and ra.isdigit()) else base_sleep * (2 ** (attempt - 1))
                time.sleep(sleep_s)
                continue

            if status == 403:
                time.sleep(base_sleep * (2 ** (attempt - 1)))
                continue

            time.sleep(base_sleep)

        return last_status, ""

Next step: start with concurrency-per-exit set to 1. If your success rate stays high and captcha rate stays low, increase slowly.

Apply proxy rotation and sticky sessions with clear rules

Rotation helps when it is controlled and auditable. It hurts when it is random.

Rotation frequency

• Search and category discovery: rotate every 5–20 requests per exit
• Product details: rotate every 10–50 requests per exit
• If captcha rate rises: rotate less, not more

Sticky sessions

• Keep the same exit for 10 minutes when scraping a single page type
• Avoid mixing regions in the same batch if you care about consistent pricing and shipping

Region selection

• Align exits to the market domain you’re scraping
• Keep separate pools per market so your benchmarks stay comparable

For controlled rotation at scale, Rotating Proxies fits well when you want predictable churn while keeping data completeness measurable. MaskProxy setups generally perform best when rotation is treated as a parameter you tune, not a lever you spam.

Next step: lock one region, one proxy type, and one cadence. Benchmark first, then scale.

Clean, dedupe, and export so the results can be used immediately

For price monitoring, competitor tracking, and inventory discovery, “usable output” usually means:

• deduped URLs
• normalized currency and shipping fields
• missing fields flagged rather than silently dropped
• stable schema exported to CSV or JSON

A beginner-safe rule: never overwrite your schema mid-run. Add new fields as optional columns and keep older output readable.

Next step: add a boolean parse_ok and a numeric completeness score per record. It turns “bad runs” into searchable causes.

Troubleshoot 403, 429, captchas, missing data, and render-loaded content

The 10-minute isolation routine

1. Check the ratio of 429 vs 403
2. Test the same URL direct vs proxy
3. Reduce concurrency and slow the cadence
4. Stabilize exits and reduce rotation
5. Confirm you are not parsing a challenge page by logging HTML length and title

Symptom to cause to fix table

Next step: treat “missing key fields” as a failure mode, not a partial success. That’s how you prevent silent data corruption.

Use a benchmark template to choose proxy plans by results, not claims

Buy proxies with numbers, not promises.

Metrics to track

• success rate: 200 plus key fields present
• block rate: 403 plus challenge-page frequency
• rate-limit rate: 429 frequency
• completeness: price, shipping, variants present
• cost per 1000 successful requests: total spend ÷ successes × 1000

Reusable evaluation table

Next step: run 200 requests first. If the trend is stable, scale to 1000 and compare cost per 1000 successes across plans.

Use Playwright only when the data appears after render

Use Playwright when the HTML source does not contain the data you need, and you can confirm it only appears after render or interaction.

Minimal Playwright example:

from playwright.sync_api import sync_playwright

def fetch_rendered(url: str, proxy_server: str | None = None) -> str:
    with sync_playwright() as p:
        launch_args = {}
        if proxy_server:
            launch_args["proxy"] = {"server": proxy_server}
        browser = p.chromium.launch(headless=True, **launch_args)
        page = browser.new_page()
        page.goto(url, wait_until="networkidle", timeout=45000)
        html = page.content()
        browser.close()
        return html

Next step: keep Playwright as a second-pass tool for incomplete records only. It saves cost and reduces risk.

Keep scraping within clean boundaries to improve stability and reduce risk

Clean scope improves stability. Public pages are simpler, and you avoid unnecessary issues by not collecting personal identifiers or bypassing access controls.

For the practical rules of robots files and typical interpretation, robotstxt.org is a useful reference. For eBay’s own service rules, review their user agreement at eBay User Agreement.

Next step: keep your dataset focused on product and listing information, and remove anything that is not required for your business decision.

Once your benchmark shows stable success rate and completeness, scale by increasing exits gradually and widening coverage while keeping cadence measurable. For large discovery runs where you want controlled churn but still care about data completeness, Rotating Residential Proxies can act as the rotation layer while you track cost per 1000 successful requests.
