How this service works
Safe web and PDF reader for agents: give it a URL, get clean markdown with hidden text, invisible characters and exfiltration links removed, a prompt-injection risk report, and the content wrapped as untrusted data. Respects robots.txt. Unreadable pages are not charged. Also: /v1/read $0.005, /v1/scan $0.002, /v1/mcp-audit $0.01, /v1/skill-audit $0.005. Remote MCP: /mcp. 10 free/new wallet.
Output
Returns the page content as clean markdown or plain text with hidden text, invisible characters, and data-exfiltration links removed. Also includes a prompt-injection risk report and wraps the content as untrusted data. Pages that are blocked, require JavaScript, or are too large are not fetched or charged.
Example use cases
Safe research browsing for agent
“I want you to fetch https://news.ycombinator.com and give me the content as clean markdown — but make sure any hidden text, invisible characters, or prompt-injection attempts are stripped out and reported before you process it.”
Vetting user-submitted URLs
“A user just gave me this URL to read: https://some-random-site.com/offer. Before my agent acts on anything in it, can you fetch it as text and tell me if there are any prompt-injection risks or data-exfiltration links hiding in the page?”
LLM pipeline content ingestion
“Pull down https://docs.someapi.com/reference for me in markdown format and sanitize it first — I need a prompt-injection risk report alongside the clean content so I know it's safe to feed into my pipeline.”
Technical details
Endpoint
POSThttps://api.powerstripsecurity.workers.dev/v1/read?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent needs to read external web pages and you want protection against prompt-injection attacks embedded in that content. It is uniquely suited for agentic pipelines where untrusted web content will be passed to an LLM, because it sanitizes hidden text and malicious links and provides an explicit risk report — something a raw scraper or generic web reader does not do. Prefer it over plain fetch tools whenever the source URL is user-supplied or potentially adversarial.
Side effects
- Page blocked by robots.txt — not charged, returns an error indicating blocked access
- Page requires JavaScript rendering — not charged, returns an error indicating JS requirement
- Page too large — not charged, returns a size-limit error
- Invalid or non-public URL (IP addresses, non-80/443 ports) — returns validation error
- Network timeout or unreachable host — returns connection error
- HTTP error codes from target site (403, 404, 500) — returned as fetch failure
