## 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-8-k-material-events-api-0df6156e
```

Example prompt: Pull all SEC 8-K material event filings for AAPL from the last 90 days and tell me if any are high-importance items like earnings results, executive changes, or cybersecurity incidents.

## When to prefer this

Use this endpoint when you need structured, factual 8-K filing data from SEC EDGAR for a specific US-listed company by ticker, especially when you want machine-readable Item codes, official Item titles, accession numbers, and high-importance flags without any sentiment or scoring overlay. Prefer this over full EDGAR scraping when you need lightweight, cost-effective per-ticker lookups with clean JSON output.

## Known failure modes

- Invalid ticker symbol returns an error or empty event array
- Ticker not found in EDGAR returns zero results
- Look-back window exceeding 365 days is rejected by schema validation
- Network or upstream EDGAR availability issues may cause timeouts
- Delisted or OTC tickers may have no EDGAR filings
- Payment of $0.01 USDC required per call; unpaid requests are rejected via x402 protocol

## How this service works

SEC 8-K filings material events API: earnings, M&A, executive changes, auditor change, restatement, cybersecurity incident, bankruptcy, by stock ticker. Extractive/factual only — accession number, EDGAR filing URL, Item numbers with official Item titles verbatim, filed timestamp, response timestamp. No buy/sell signals, scores, sentiment, or rankings. highImportance is a fixed Item-number rule (1.02, 1.03, 1.05, 2.04, 2.05, 2.06, 3.01, 4.01, 4.02, 5.01), not a judgment. Informational only, not investment advice. Data: SEC EDGAR (public domain). Verify at source; provided as-is, no warranty.

## Output

Returns a JSON object with the company name, CIK, ticker, look-back window, and an array of 8-K filing events. Each event includes the accession number, direct EDGAR URL, form type (8-K or 8-K/A), filed timestamp, report date, list of SEC Item codes with official verbatim titles, and a highImportance boolean based on a fixed set of Item numbers (1.02, 1.03, 1.05, 2.04, 2.05, 2.06, 3.01, 4.01, 4.02, 5.01). Also returns total count, high-importance count, and a disclaimer.
