3. What User-Agent & AI Bot Parser API Detects & Validates

Identifies 30+ AI crawlers and distinguishes training scrapers vs live user-triggered AI search/RAG fetchers (GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, PerplexityBot, Google-Extended, CCBot, Bytespider)
Detects headless automation and CLI clients (HeadlessChrome, Playwright, Puppeteer, Selenium, curl, python-requests, Go-http-client)
Extracts browser family/version, rendering engine, OS family/version, and device type (mobile, tablet, desktop, tv, bot)

Honest Engineering Boundaries

4. Known Limitations & Test Verification

Release Version: v1.0.7 · Last Verified / Benchmarked: 14 November 2026 · Latency Note: Sub-millisecond figures measure in-Worker V8 compute time (typical client HTTPS network RTT to the nearest Cloudflare PoP is 15–65 ms) · See Full Portfolio Benchmarks & Corpora →

User-Agent strings can be spoofed by malicious scrapers; combine with reverse-DNS/IP range verification for high-security blocking.
Tested v1.0.4 (14 November 2026).

6. Frequently Asked Questions

Does it distinguish AI training scrapers from live AI search citations?

Yes! For example, it separates OpenAI's GPTBot (training) from OAI-SearchBot and ChatGPT-User (search/user browsing).

Can I pair this with robots.txt & llms.txt analysis?

Yes, use POST /v1/robots-llms-analyzer to audit and generate your site's AI crawler rules.

How fast is it?

Typically under 1 ms at the edge.

Zero Payload Logging

7. Data Handling, Privacy & Marketplace Proxy Disclosure

Stateless in-memory User-Agent parsing.

Worker Zero-Logging Guarantee: Cloudflare Workers Observability and invocation logging are disabled in configuration (observability.enabled = false, head_sampling_rate = 0, invocation_logs = false). Payloads are processed strictly in volatile V8 memory and never logged or stored by Tinplate.

Marketplace Proxies vs. Direct Bearer Key: Requests sent via RapidAPI or Zyla API Hub pass through those marketplaces' proxy infrastructure (subject to their respective privacy policies). Security-sensitive workloads requiring end-to-end zero-intermediary processing can connect directly to https://api.tinplate.dev using a Direct Bearer Key (Authorization: Bearer <API_KEY>).
