How this service works
86 APIs for AI agents: web scraping and crawling to Markdown, AI summaries, data extraction and cited answers, screenshots and PDF, PDF, OCR and document conversion, news, paper and developer search and more, paid per call with USDC on Base, Solana, Polygon or Arbitrum via x402. No account, no API key, free sample on every service.
Output
Returns a JSON object with fully parsed user agent details: browser name, major version, and full version; OS name and version; device type (mobile/tablet/desktop), model, and vendor; CPU architecture; rendering engine name and version; plus boolean flags for is_mobile, is_tablet, is_bot, and is_ai_crawler.
Example use cases
Bot traffic detection in logs
“I have this user agent from my server logs — can you tell me if it's a real browser or a bot? Here it is: 'Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)'”
Mobile vs desktop segmentation
“Can you parse this user agent and tell me whether it came from a mobile phone, tablet, or desktop? The string is: 'Mozilla/5.0 (Linux; Android 13; Pixel 7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Mobile Safari/537.36'”
AI crawler identification
“Check if this user agent belongs to an AI crawler or scraper — I want to know if it's a known AI agent hitting my site: 'Mozilla/5.0 (compatible; GPTBot/1.0; +https://openai.com/gptbot)'”
Technical details
Endpoint
POSThttps://agentsvc.io/api/v1/proxy/useragent-parse?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, field-level breakdown of a raw User-Agent string at low cost ($0.002/call), especially when you need bot detection or AI crawler flagging alongside standard browser/OS/device parsing, without needing to set up an account or API key. Ideal for per-event enrichment in serverless or agent workflows paying per call via USDC on Base.
Side effects
- Empty or missing user_agent field returns an error or null-populated response
- Highly non-standard or obfuscated user agent strings may result in null fields for unrecognized components
- Very new browser/OS versions not yet in the parser database may be misidentified
- Spoofed user agents will be parsed at face value without deception detection
