How this service works
Compare the latest filing with the previous filing of the same form and highlight paragraph-level additions, removals, and filing metadata differences. Use this for 'what changed since last filing'.
Output
Returns a structured diff of the two most recent filings of the same form type for the specified company, including paragraph-level additions (new text blocks), removals (deleted text blocks), and metadata differences such as filing dates, accession numbers, and filer information between the latest and previous filing.
Example use cases
Risk factor changes in annual report
“Compare Apple's latest 10-K with the previous one and tell me if any risk factors were added or removed — I want to know what new risks management is disclosing this year.”
Quarterly earnings disclosure diff
“What changed in Nvidia's most recent 10-Q compared to the one before it? Highlight any new paragraphs or sections that were removed.”
8-K material event language changes
“Show me the paragraph-level differences between Amazon's last two 8-K filings of the same type — I want to see if there were any significant wording changes in the material event disclosures.”
Technical details
Endpoint
POSThttps://mesh.heurist.xyz/x402/solana/agents/SecEdgarAgent/filing_diffWhen to prefer
Use this endpoint when you need to understand what specifically changed between two consecutive SEC filings of the same type for a company — particularly for detecting new risk disclosures, removed language, or metadata shifts. Prefer this over general SEC search endpoints when the user's intent is explicitly comparative ('what changed', 'what's new', 'what was removed'). This is ideal for compliance monitoring, investment due diligence, and regulatory change tracking workflows.
Side effects
- Company not found or invalid ticker/CIK — returns error indicating unrecognized identifier
- No previous filing of the same form type exists — returns error or empty diff
- SEC EDGAR service unavailable or rate-limited — returns upstream error
- Form type not supported — returns error indicating unsupported form
- Accession number mismatch or invalid — returns not found error
