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%').
Example use cases
Pre-earnings financial snapshot
“Give me a quick SEC filing brief on Nvidia — I need the latest 10-K and 10-Q figures, how revenue and net income changed from the prior period, and any signals like recent filings or margin metrics before the earnings call.”
Investor due diligence on a new position
“I'm evaluating Microsoft as a new position — can you pull their filing brief showing filing cadence over the last 90 days, form type counts, and the latest XBRL financials with period-over-period changes?”
Screening for unusual filing activity
“Check the SEC filing brief for Palantir and flag any signals — like a new 8-K in the last 7 days, unusual filing frequency, or significant swings in their reported financials versus the prior period.”
Technical details
Endpoint
GEThttps://x402-data-api.x402agent.workers.dev/filing-brief?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
