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 SEC filings of the same form type, including paragraph-level additions (new text blocks), removals (deleted text blocks), and differences in filing metadata such as filing dates, accession numbers, and filer information.
Example use cases
Risk factor change detection
“Pull up the diff between Microsoft's latest 10-K and the one before it — I want to see exactly which risk factor paragraphs were added or removed this year.”
Earnings filing disclosure monitoring
“Compare Apple's most recent 10-Q with the previous quarter's 10-Q and highlight any new disclosures or paragraphs that were deleted.”
M&A due diligence filing review
“What changed in Pfizer's latest annual SEC filing versus the prior year's? I need to see all paragraph-level additions and removals across the full document.”
Technical details
Endpoint
POSThttps://mesh.heurist.xyz/x402/agents/SecEdgarAgent/filing_diffWhen to prefer
Use this endpoint when you need to understand exactly what changed between two consecutive SEC filings of the same type (e.g., two 10-Ks or two 10-Qs) at the paragraph level. Prefer this over manually fetching two filings when the goal is change detection, compliance monitoring, or investment research focused on disclosure shifts. Not suitable for retrieving full filing content without comparison context.
Side effects
- Company not found in EDGAR — returns error if CIK or ticker is invalid
- No previous filing exists to compare against — returned when it is the first filing of that form type
- Form type not supported — error if the specified form type is not available in EDGAR
- Rate limit or payment failure — HTTP 402 if USDC payment is not processed
- Timeout for very large filings with many pages
