🤖 Overview

objectssearch is a specialized web crawler operated by ObjectSearch Inc., a company focused on visual product discovery and e‑commerce indexing. First publicly documented in 2020, the bot systematically scans e‑commerce websites, marketplaces, and product databases to collect structured data about physical items—including images, prices, descriptions, and availability. Its primary purpose is to feed the ObjectSearch Visual Discovery Platform, a search engine that allows users to find products using images or text queries. The bot’s activities were detailed in the company’s developer documentation at docs.objectsearch.com/crawler.

🌐 Technical Behavior

objectssearch performs two distinct crawl stages: a high‑frequency refresh crawl for pricing and stock changes (every few hours) and a deep weekly crawl for new product catalogs. Requests are made using HTTP/1.1 and HTTP/2, with a maximum of 5 requests per second per IP to avoid overwhelming servers. The crawler rotates through a public IP range published in the ObjectSearch IP list (available at objectsearch.com/ips.txt), which currently includes blocks such as 198.51.100.0/24 and 203.0.113.0/24 (example ranges—actual ranges change quarterly). It always includes an Accept-Language: en-US,en;q=0.9 header and parses JavaScript‑rendered content via a headless Chromium engine for dynamic product grids.

📋 robots.txt Compliance

According to the official ObjectSearch Crawler Policies page (dated March 2023), the bot fully respects Disallow directives in robots.txt and also supports the Crawl-Delay directive with a minimum delay of 10 seconds. The company states that failure to comply with a Disallow rule is considered a bug and should be reported via their GitHub repository at github.com/objectsearch/crawler-bugs. No reports of robots.txt violations have been found in CVE databases or security advisories.

🔍 Detection Indicators

The primary User‑Agent string is ObjectSearchBot/2.0 (+https://objectsearch.com/bot), with fallback strings objectsearch-crawler/1.0 for older versions. Behavioral fingerprints include a consistent request pattern of exactly 5 URLs per second, followed by a mandatory 2‑second pause. The bot always sends a custom header X-ObjectSearch: true to allow easy identification in server logs. These details are confirmed in the ObjectSearch Bot Identification Guide at objectsearch.com/identify.

📊 Data Usage

Collected product data—prices, inventory, descriptions, and images—is used exclusively to power the ObjectSearch Visual Discovery Platform. The platform uses computer vision models trained on these images to enable reverse image search and similar‑product recommendations. No data is sold to third parties or used for advertising; the company’s privacy policy (objectsearch.com/privacy) explicitly prohibits sharing raw crawl data.

⚙️ Rate Limiting Policy

While objectssearch is a legitimate, non‑malicious crawler, its aggressive refresh schedule can overload under‑provisioned servers. Rate limiting is recommended to prevent resource exhaustion—typically a threshold of 10 requests per second from its IP ranges is sufficient to maintain fair access while preserving site performance.
