## 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-concept-time-series-3e4718be
```

Example prompt: Can you pull the full history of Apple's net income from SEC EDGAR filings? Apple's CIK is 320193 and the XBRL concept is us-gaap:NetIncomeLoss.

## When to prefer this

Choose this endpoint when you need structured time-series data for a specific XBRL financial concept (e.g. net income, revenue, EPS) for a specific public company, identified by CIK. It is ideal for investment research, financial modeling, or building charts of fundamental metrics over time. It requires no API key or account — only a USDC micropayment per call — making it well-suited for AI agents operating autonomously. Prefer this over scraping SEC HTML pages or using paid financial data vendors when you want raw, source-of-truth XBRL data directly from the regulator's database at low cost.

## Known failure modes

- Unknown CIK — company not found in EDGAR returns an error (not charged)
- Invalid or unsupported XBRL tag returns an error (not charged)
- Company has no XBRL data for the requested concept (empty values array)
- SEC EDGAR upstream rate limit or temporary unavailability
- Malformed tag format (missing namespace prefix like us-gaap:)

## How this service works

SEC EDGAR data for AI agents, paid per call in USDC via x402 (no account, no API key): ticker/CIK lookup, company profiles, recent filings (10-K, 10-Q, 8-K, Form 4…) with document links, key annual XBRL fundamentals and any XBRL concept time series. Public SEC data, cached, fetched under SEC fair-access rules. Errors are never charged.

## Output

Returns a JSON object containing the company CIK, the XBRL concept tag requested, the unit of measure (e.g. USD, shares), and an array of reported values each with a start date, end date, filing form type (10-K, 10-Q, etc.), and the numeric value reported in that period.
