## 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 stablefinance-company-facts-ciks-5ff04060
```

Example prompt: What are the SEC CIK numbers for publicly traded companies available in the Financial Datasets AI database? I need the list of CIK identifiers like Apple's 0000320193.

## When to prefer this

Use this endpoint when you need to enumerate available company CIK identifiers from the Financial Datasets AI dataset, particularly as a prerequisite step before fetching company-specific financial facts or SEC filing data. Prefer this over manual SEC EDGAR lookups when you need a pre-vetted list of supported companies with pay-per-use micropayment access.

## Known failure modes

- Invalid or unsupported properties filter returns empty or error response
- Payment failure via x402 returns 402 status with payment required details
- Rate limiting or quota exceeded returns 429 error
- Network timeout if upstream Financial Datasets AI is unavailable

## How this service works
