How this service works
Read a permitted public HTML, text or text-layer PDF source on demand. Return a concise AI brief with source-matched evidence quotes, retrieval time, source hash and explicit reading limits. No OCR or private URLs. Generation begins only after payment verification; failed generation does not settle.
Output
A concise AI-generated brief summarizing the fetched document, including verbatim evidence quotes matched to the source text, the exact retrieval timestamp, a hash of the source content for verification, and explicit notes on any reading limits applied. No OCR-derived content; only text-layer or HTML sources are processed.
Example use cases
Policy brief from public government report
“Fetch this public government PDF at https://agency.gov/annual-report.pdf — permission confirmed — and give me a concise brief with verbatim evidence quotes so I can cite the key findings in my policy memo.”
Fact-checking a news article
“Read the article at https://news-site.org/story/climate-data.html, I confirm it's a permitted public page, and return an AI brief with direct quotes from the text so I can verify what claims are actually made in the source.”
Research summary from academic web page
“Pull the content from https://university.edu/research/study-overview.html — it's a permitted public page — and summarize it for me with source-matched evidence quotes and a hash so I know exactly what version I'm working from.”
Technical details
Endpoint
POSThttps://instructional-decision-engine-x402.vercel.app/ai/document-evidence?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to fetch a specific, known public URL and receive a structured AI brief with source-matched evidence quotes and a source hash for auditability. Ideal for research, fact-checking, and policy work where verbatim citation and provenance (hash + retrieval time) matter. Prefer this over generic web scrapers when you need evidence quotes rather than raw HTML, and over general summarizers when source verification and reading-limit transparency are required.
Side effects
- URL points to a private, paywalled, or non-public resource — request rejected
- URL contains query parameters or fragment identifiers (pattern requires clean HTTPS path) — validation error
- Source requires OCR (image-based PDF) — not supported, returns error
- permissionConfirmed not set to true — request rejected
- Payment verification fails — generation does not begin, no charge settled
- Source content exceeds reading limits — partial brief returned with explicit limit notice
- Network timeout or unreachable URL — retrieval error returned
