Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-m-a-8-k-filings-monitor-abcc630d
```

Example prompt: Pull all SEC EDGAR 8-K merger and acquisition filings detected since 2025-01-01T00:00:00Z, limit to 50 results, and only show me ones with a significance score of at least 7.

## When to prefer this

Use this endpoint when you need a real-time or recent feed of SEC-disclosed merger and acquisition events from EDGAR 8-K filings, especially when you want to filter by recency (since timestamp) and significance. Prefer this over general news search when you need authoritative, primary-source regulatory filings with direct links to EDGAR, or when building automated pipelines to monitor M&A activity.

## Known failure modes

- Invalid or missing 'since' parameter returns a 400 error
- 'limit' out of range (below 1 or above 500) returns a 400 validation error
- 'min_significance' out of range (below 1 or above 10) returns a 400 validation error
- No filings found in the window returns an empty 'changes' array with count 0
- Payment not provided or invalid returns a 402 error
- EDGAR upstream unavailable may return 503 or empty results

## How this service works

SEC EDGAR 8-K filings matching merger / acquisition agreements since a timestamp — company name, CIK, form, filing date, and a direct link to the filing index.

## Output

A JSON array of M&A-related 8-K filing events, each containing the company name, CIK identifier, form type, filing date, a direct link to the SEC EDGAR filing index, a significance score (1–10), a plain-language summary, the detection timestamp, and the effective date if available — plus a total count and source label.
