AI Citation Analysis API for Source Evidence

Compare AI answer claims with cited page evidence using Source Influence. Inspect supported passages, unsupported citations and source coverage.

Check whether a citation supports the claim

A citation link does not verify every claim in an answer. Source Influence splits the answer into claims and checks them against source pages, returning evidence excerpts, locations and support ranges. Sources without supplied bodies are fetched; unread sources are marked unfetched.

Claim verdicts and source coverage

exclusive means one publisher supports a claim within the inspected set; corroborated means multiple publishers do. uncited means no support and no inline citation were found. washed means an inline citation exists but no inspected source supports the claim. Unread sources remain uncertainty.

Find what a cited page actually contributes

Suppose an answer describes a product’s weight and warranty and cites two pages. Comparing evidence passages can show whether a page supports only the weight claim, leaving the warranty unsupported. This is an illustrative workflow, not a measured customer result.

  • Use Answers to collect the response and count its citation URLs.
  • Pass the original answer with its citation markers and the corresponding sources to Source Influence.
  • Review evidence excerpts and unread sources together before deciding what content to update.

Submit through the dedicated endpoint

Send original Markdown and citations to POST /v1/source-influence. The following illustrates the input format; replace example.com with a real citation URL. Results use the standard task polling or webhook contract.

{
  "answer": "The original AI answer to analyze",
  "citations": [
    {
      "url": "https://example.com/source",
      "body": "The actual text of the cited page"
    }
  ]
}

Evidence analysis is not proof of causation

This is post-hoc comparison of an existing answer with supplied or fetched sources. It cannot inspect the model’s internal generation process or prove that a source caused a sentence. Interpret evidence coverage together with fetch failures.

Usage-based analysis pricing

Analysis is metered separately from the 1–2 credit answer engines. Model usage, source fetching and analysis options affect the charge. Read the documented metering and limits before scheduling analyses.
