## 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-filing-section-retrieval-12218e5e
```

Example prompt: Can you pull the Risk Factors section (Item 1A) from Apple's 10-K filing with accession number 0000320193-23-000106 so I can see what they disclosed?

## When to prefer this

Choose this endpoint when you need the raw text of a specific SEC filing section pinned to an exact accession number, particularly as a precursor to year-over-year diff analysis. Prefer it over general SEC EDGAR access when you need structured, per-section extraction with guaranteed accession-number fidelity rather than full-document retrieval.

## Known failure modes

- Invalid or malformed accession number returns an error or empty result
- Requested section does not exist in the specified filing
- Filing not yet indexed returns a not-found response
- Rate limiting or payment failure with x402 protocol returns 402 status
- Section identifier not recognized for the given filing type

## 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

Returns a JSON object containing the section item identifier (e.g. '1A'), the full text of that SEC filing section, a boolean indicating whether the result is pinned to the accession number, and a character count of the returned text.
