How this service works
PE paid route /v1/citation-check
Output
The agent receives a structured verification result indicating whether the citation is valid, whether the cited source exists, whether the stated claim or statistic matches what the source actually says, and any identified discrepancies or errors in the citation formatting or content.
Example use cases
Academic paper citation audit
“I'm submitting my thesis next week and need you to verify this citation: 'Jones, M. (2020). Climate feedback loops. Nature, 45(3), 112-118.' — does the source exist and does it actually support my claim about arctic ice melt?”
Journalism fact-check before publication
“Before we publish this news piece, can you verify that this citation checks out: 'According to the WHO 2022 report, global vaccination rates reached 68%' — make sure the source is real and the stat is accurate.”
Legal brief reference validation
“Check this citation I'm including in a legal brief: 'Rodriguez v. City of Miami, 2019 WL 4894321 (S.D. Fla. Oct. 4, 2019)' — I need to know if it exists and is cited correctly.”
