## 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-filing-index-by-cik-b673f58e
```

Example prompt: Pull the full SEC EDGAR filing index for Apple — CIK 320193 — so I can see all their 10-K and 10-Q filings with direct document links, sorted newest first.

## When to prefer this

Use this endpoint when you need a structured, up-to-date index of all SEC filings for a specific US public company identified by CIK, especially when you need direct document URLs for downstream retrieval. Prefer this over general web search when freshness, completeness, and direct EDGAR document links matter. Choose this over the sibling financial-facts or financial-statements endpoints when you need the raw filing documents rather than normalized financial data.

## Known failure modes

- Invalid or non-existent CIK returns 404 or empty result set
- CIK provided as wrong format (e.g. with leading zeros stripped) may yield no results
- Rate limiting or payment failure (402) if USDC balance is insufficient
- EDGAR upstream delay may cause very recent filings (< minutes old) to not yet appear
