# x402-factory EDGAR 8-K Events Delta

> x402-factory EDGAR 8-K Events Delta is a paid API for AI agents from x402-factory.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns only the 8-K SEC filings added or changed since a given cursor, enabling efficient incremental polling without reprocessing the full dataset

## 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 x402-factory-edgar-8-k-events-delta-2a7c765f
```

Example prompt: Fetch any 8-K SEC filings that were added or changed since my last cursor — use cursor 'eyJsYXN0X2lkIjoxMjM0NX0' — and give me the new filings, changed count, and the next cursor to use next time.

## When to prefer this

Choose this endpoint when you need incremental, cost-efficient polling of SEC 8-K filings — paying only $0.01 per delta call rather than fetching the full dataset. Ideal for agents that continuously monitor corporate disclosures, compliance pipelines that need to stay synchronized, or alerting systems that trigger on new material events. Use the free sibling /v1/edgar/events/changes to check changed_count before committing to a paid delta call.

## Known failure modes

- Invalid or expired cursor returns an error or resets to current position
- Missing or malformed 'since' parameter causes bootstrap behavior (returns cursor at now)
- Rate limiting or payment failure (402) if USDC payment not included
- Empty rows array when no filings have changed since the cursor
- Network timeout on slow EDGAR upstream response

## How this service works

Only the 8-K filings changed since your cursor (delta of /v1/edgar/events) — Keyset delta of /v1/edgar/events: pass since=<next_cursor from your last call> and get only the 8-K filings added or changed after it, plus changed_count and a new next_cursor. Omit since once to bootstrap. Cursors are stable across restarts. Poll the free sibling /v1/edgar/events/changes for counts and pay only when…

## Output

Returns a JSON object with a 'rows' array of 8-K filing objects (each containing accession number, CIK, ticker, company name, form type, filed_at timestamp, and classified_type), a changed_count integer indicating how many filings changed, an as_of timestamp, and a next_cursor string to use in the subsequent poll.
