## 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-sec-filings-list-43cd9a57
```

Example prompt: Pull the list of 10-K filings for NVIDIA from Signal Nodus so I can get the accession numbers and compare this year's risk factors section to last year's.

## When to prefer this

Choose this endpoint when you need to discover available SEC filings and their accession numbers for a company before retrieving year-over-year section diffs. It is the entry point into the Signal Nodus diff workflow — use it to enumerate filings, then pass accession numbers to diff endpoints. Prefer this over raw EDGAR queries when you need structured, diff-ready filing metadata in a single paid API call.

## Known failure modes

- Unknown or invalid company identifier returns empty filings array
- Invalid form type filter returns no results
- Rate limiting or payment failure returns 402 Payment Required
- Company has no filings matching the requested criteria
- Malformed request parameters return 400 Bad Request

## 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 an array of filings, each with form type (e.g. '10-K'), filing date, and accession number, plus a count of returned results. These accession numbers serve as keys to retrieve year-over-year section diffs from sibling endpoints.
