How this service works

AxonGate Source Trust Check: citation-backed decision on whether a source is safe to cite.

Output

A structured, citation-backed evidence report summarizing what the target URL establishes in response to the specified question, including supporting citations and source evaluation, at the requested depth level (quick, standard, or deep).

Example use cases

Fact-check competitor marketing claims

“I need you to pull a quick AxonGate report on our competitor's homepage and tell me which claims about their product performance actually have citations backing them up.”

Audit legal source for court evidence

“Can you do a deep-level AxonGate analysis on that regulatory filing URL and identify all the citations supporting their assertions about compliance with EPA standards?”

Verify news article credibility fast

“Run a standard AxonGate check on this news article about the merger and let me know what evidence it actually cites versus what's just speculation.”

When to prefer

Use this endpoint when you need a structured, citation-backed evidence report on a specific public URL — especially when you need to answer a targeted research question about what a source proves or establishes. It is preferable over generic web scrapers when auditability, citation depth, and evidence framing matter. Choose quick for fast checks, standard for balanced analysis, and deep for comprehensive sourcing.

Side effects

Invalid or unreachable target URL returns an error
Unsupported URL format (non-HTTP/HTTPS) rejected
Payment challenge mismatch if pack level not passed as query param or header
Cache miss may increase latency for non-refreshed sources
Deep pack with force_refresh may time out on large pages

Input

{
  "pack": "standard",
  "question": "What does this source establish?",
  "target_url": "https://example.com",
  "force_refresh": false
}

Schema · Request body

question	string	Evidence objective or buyer question.
target_url	string	Absolute public HTTP/HTTPS URL to evaluate.
force_refresh	boolean	Bypass source cache. Deep packs refresh by default.
