## 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 sec-edgar-xbrl-financial-fundamentals-lookup-41753a66
```

Example prompt: Pull Apple's annual Revenues from SEC EDGAR — Apple's CIK is 320193, use the us-gaap taxonomy, and give me the 8 most recent fiscal year values.

## When to prefer this

Use this endpoint when you need official, authoritative XBRL financial data (revenues, assets, net income, etc.) for a US SEC-registered public company, sourced directly from SEC EDGAR. Prefer it over third-party financial data APIs when regulatory accuracy and public-domain provenance matter, or when you already have the company's CIK and a specific XBRL concept tag to query.

## Known failure modes

- Invalid or unknown CIK returns an empty or error response
- Unknown XBRL tag for the given taxonomy returns no data
- Limit out of range (must be 1-40) may cause validation error
- Company has not filed XBRL data for the requested concept — empty units array
- Payment not completed (HTTP 402 returned with machine-readable quote until x402 payment confirmed)
- Network timeout or SEC EDGAR upstream unavailability

## How this service works

As-filed XBRL fundamentals for any SEC-registered company, straight from the EDGAR companyconcept API (updated as filings are accepted). Query: ?cik=320193 (Apple) &tag=Revenues|Assets|NetIncomeLoss|EntityCommonStockSharesOutstanding... &taxonomy=us-gaap|dei (default us-gaap) &limit=N most recent facts per unit (1-40, default 8). Each fact carries period, value, fiscal year/period, form type and filing date, grouped by unit (USD, shares...). Served with a 12h cache.

## Output

Returns a JSON object with the company name, XBRL tag label, and an array of financial values per unit (e.g. USD) including the fiscal period, fiscal year, start/end dates, filing form type, filing date, and the reported numeric value. Source is attributed to SEC EDGAR XBRL public domain data.
