## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability signal-nodus-latest-sec-filings-1b4b9ea3
```

Example prompt: Pull the latest 8-K filings from Signal Nodus so I can see which companies recently disclosed material definitive agreements, with their accession numbers.

## When to prefer this

Choose this endpoint when you need structured, accession-number-pinned access to the latest SEC filings with year-over-year diff signals, particularly for 8-K or similar event-driven forms. Prefer it over raw EDGAR scraping when you want pre-processed, diff-highlighted sections ready for analysis without building your own change-detection pipeline. Best suited for compliance monitoring, investment research alerting, and regulatory change tracking at $0.01 per call.

## How this service works

Signal Nodus: year-over-year diffs of SEC filing sections, pinned to accession numbers. The diff is the product; raw data is the on-ramp.

## Output

A JSON object containing the queried form type (e.g. '8-K'), a list of up to 20 recent filings each with company name, accession number, form type, and an array of reported items with item codes and titles, plus a count of returned filings.
