## 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-financials-8ecf7bf2
```

Example prompt: Pull the year-over-year diffs for Apple's total Assets from their SEC filings — I want the last 40 reported values in USD, pinned to their accession numbers.

## When to prefer this

Choose this endpoint when you need structured, accession-number-pinned financial facts from SEC EDGAR filings, especially for year-over-year diffing of XBRL concepts like Assets, Liabilities, or Revenue. Prefer it over raw SEC EDGAR APIs when you want pre-processed, diff-ready data without parsing raw XBRL yourself. Best for financial research, earnings analysis, and automated monitoring of public company fundamentals.

## Known failure modes

- Unknown or invalid financial concept returns empty facts array
- Invalid ticker or CIK returns 404 or empty response
- Rate limiting or payment failure returns 402 Payment Required
- SEC EDGAR data lag may mean the most recent filing is not yet indexed
- Concept name case sensitivity or XBRL namespace mismatch may return no results

## 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 financial concept name, the unit (e.g. USD), and an array of up to 40 fact objects each with a reporting end date and value, representing historical data points extracted from SEC filings — suitable for computing year-over-year diffs.
