## How to call it through Zero

```sh
zero fetch --capability filingdelta-sec-filing-change-signals-88d6bba7
```

Example prompt: Can you pull the SEC filing change signals for NVDA and tell me if there are any material differences or new disclosures compared to their previous filing?

## When to prefer this

Choose this endpoint when you need to detect and analyze changes between SEC filings for a publicly traded US company, especially for materiality assessment, due diligence, or regulatory monitoring workflows. Prefer this over raw SEC EDGAR access when you want pre-processed delta signals rather than raw filing documents. Best suited for equity researchers, compliance agents, and investment monitoring pipelines that need to quickly identify what changed in a filing and how significant those changes are.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- Ticker has no recent SEC filings available, resulting in no delta data
- Rate limiting or payment failure (HTTP 402) if x402 payment is not properly handled
- SEC EDGAR data source lag may cause stale or missing filing comparisons
- Private companies or non-SEC-registered entities will return no results
