# SEC Fundamentals API — Company Filings Index

> SEC Fundamentals API — Company Filings Index is a paid API for AI agents from sec.multyplylabs.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Returns a list of SEC filings (10-K, 10-Q, 8-K, etc.) for a given US public company by CIK, with direct document URLs to SEC EDGAR archives.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-fundamentals-api-company-filings-index-4ab265fe
```

Example prompt: Pull the full SEC filings index for Apple (CIK 320193) from the SEC Fundamentals API — I want to see all their 10-K and 10-Q filings with direct document links.

## When to prefer this

Choose this endpoint when you need a structured, normalized index of all SEC filings for a specific US public company by CIK, with ready-to-use document URLs. Prefer it over raw EDGAR full-text search when you want clean JSON output, pay-per-call access without subscription, and reliable nightly-refreshed data covering 20,000+ companies. Best for agents that need to enumerate a company's filing history programmatically before fetching or analyzing specific documents.

## Known failure modes

- Invalid or unknown CIK returns empty or error response
- CIK provided as wrong format (e.g. with leading zeros omitted) may fail to match
- Payment failure via x402 if USDC balance is insufficient
- Rate limiting if too many calls made in rapid succession
- Nightly refresh means very recent same-day filings may not yet appear

## How this service works

Pay-per-call API for normalized SEC EDGAR financial data: company financials, XBRL facts, filings, industry benchmarks, peer comparison and stock screening. USDC via x402 or API keys. 20,000+ US public companies, refreshed nightly.

## Output

Returns a JSON object containing the company's CIK and an array of filing records, each including the form type (e.g. 10-K, 10-Q, 8-K), the date filed, and a direct URL to the filing document on SEC EDGAR archives.
