## 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-event-feed-api-c16be292
```

Example prompt: Pull the latest SEC 8-K filings from the past 3 days for TSLA and flag any that are high-impact or suggest possible share dilution.

## When to prefer this

Choose this endpoint when you need real-time SEC 8-K filing data enriched with pre-decoded item codes and semantic flags (high-impact, dilution) specifically optimized for trading bots and automated financial workflows. Prefer this over raw EDGAR scraping when you need structured, filterable output without parsing raw XML filings. Best suited for latency-sensitive trading pipelines, event-driven agents, and portfolio monitoring systems that need to act on corporate disclosures quickly.

## Known failure modes

- Invalid or unrecognized ticker returns empty filings array
- Unsupported item code filter returns no results or validation error
- Days parameter out of range may return empty results or error
- Rate limiting or payment failure returns 402 Payment Required
- EDGAR upstream delay may cause stale or missing filings
- Malformed query parameters return 400 Bad Request

## How this service works

Exact EVM address, calldata, Uniswap V2/V3 and impermanent-loss math. Pay per call in USDC on Base via x402.

## Output

Returns a JSON object with a count and array of filing objects. Each filing includes the company name, ticker symbols, file date, decoded item codes (e.g. '2.02', '9.01'), a boolean highImpact flag indicating market-moving potential, a possibleDilution boolean flag, and a link to the filing on EDGAR.
