## 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 vellum-filing-brief-ac2c3376
```

Example prompt: Pull up the full SEC filing brief for Apple — I want the latest filings by form type, how often they've been filing, their newest XBRL revenue and net income figures with the change versus last period, and any pre-computed signals.

## When to prefer this

Choose this endpoint when you need a complete, one-call SEC intelligence package for a single company — covering filing cadence, XBRL financials with deltas, and pre-computed signals — without chaining multiple EDGAR queries or parsing raw XBRL. Prefer it over the sibling vellum-filing-delta endpoint when you want a broad current snapshot rather than a narrow date-window diff, and over vellum-sec-research when you want computed signals and financials rather than raw registry and filing links.

## Known failure modes

- Unknown ticker or CIK returns empty or error response
- Company with sparse EDGAR history may return limited XBRL figures
- Stale data if EDGAR indexing lags behind the latest filing date
- $0.75 USDC payment required per call — missing or invalid x402 payment header returns 402 Payment Required
- Rate limiting or worker downtime may cause 503 errors

## How this service works

Cited SEC filing brief with company profile, filing activity, latest financials, period changes, signals and EDGAR source URLs.

## Output

A JSON object containing: company metadata (CIK, ticker, SIC), filing activity stats (per-form counts, filings last 90 days, total indexed, days since latest filing), latest XBRL financial figures with value, prior value, period end date, filed date, and percent change, plus a list of pre-computed human-readable signals (e.g. 'new filing within 7 days', 'net margin 23.97%').
