How this service works
Fetch a URL safely and get back sanitized, agent-ready page text plus a prompt-injection verdict (SAFE / REVIEW / BLOCK). Detects instructions hidden in markup, invisible Unicode, homoglyph and encoded payloads, delimiter spoofing and data-exfiltration bait — so an agent never ingests hostile content. Use before feeding any fetched page into an LLM.
Output
Returns sanitized, agent-ready plain text extracted from the fetched page, along with a prompt-injection verdict of SAFE, REVIEW, or BLOCK. The verdict reflects detection of hidden markup instructions, invisible Unicode characters, homoglyph substitutions, encoded payloads, delimiter spoofing, and data-exfiltration bait. Agents can use the text only if the verdict is SAFE or acceptable under their policy.
Example use cases
Agent reading user-submitted URLs
“A user just pasted https://some-blog.com/post into my chatbot and asked me to summarize it. Before I fetch and summarize it, can you run it through SafeFetch to make sure the page doesn't contain any prompt-injection tricks or hidden instructions?”
Research agent pre-flight check
“I'm building a research agent that browses URLs from search results. Can you SafeFetch https://news-site.com/breaking-story and give me the sanitized page text plus the SAFE/REVIEW/BLOCK verdict before I pass it to my summarizer?”
Content pipeline security gate
“We're scraping product pages for an e-commerce comparison tool. Before processing https://competitor-shop.com/product/widget, scan it with SafeFetch so we know if there are any embedded prompt injections or data-exfiltration baits hiding in the markup.”
Technical details
Endpoint
GEThttps://api.trustsource.cc/safefetchWhen to prefer
Use this endpoint whenever an AI agent needs to fetch and process content from an external URL before passing it to an LLM — especially when the URL is user-supplied, untrusted, or from an unknown source. It is the right choice over a plain HTTP fetch when prompt-injection safety matters, since it combines content retrieval, sanitization, and threat classification in one call. Prefer it over generic web-scraping APIs when you need the SAFE/REVIEW/BLOCK verdict alongside clean text, rather than raw HTML or structured data extraction.
Side effects
- URL is unreachable or returns a non-200 HTTP status — endpoint may return an error or empty content
- Target page blocks crawlers (robots.txt disallowed) — content may not be retrievable
- Page is behind authentication or a paywall — sanitized text will be incomplete or empty
- Very large pages may be truncated or time out
- Dynamic JavaScript-rendered content may not be fully captured if the page requires JS execution
- Missing or malformed 'url' query parameter causes a validation error
