## 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-watch-form-delta-5ffabb1c
```

Example prompt: Check for any new or changed IPO-watch filings on EDGAR since my last cursor — give me the delta with the next cursor so I can keep polling.

## When to prefer this

Use this endpoint when you need efficient incremental polling of EDGAR filings for a specific watched form type (IPO, activist, offering, annual, delisting, or proxy) without re-fetching the full dataset each time. Prefer over the sibling /changes endpoint when you want a keyset-paginated delta with stable cursors and a changed_count, suitable for automated agent pipelines that need to resume exactly where they left off across restarts.

## Known failure modes

- Invalid or expired cursor returns an error or resets state
- Unknown form enum value returns a 400 bad request
- Omitting the required form path param returns a 404
- Network or upstream EDGAR outage may return 5xx
- Cursor from incompatible API version may be rejected

## How this service works

Only the filings of the watched form changed since your cursor (delta of /v1/edg — Keyset delta of /v1/edgar/watch/:form: pass since=<next_cursor from your last call> and get only the filings of the watched form 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/watch/:form/changes…

## Output

Returns an array of filing rows (each with accession number, CIK, ticker, company name, form type, filing timestamp, and classified type), a changed_count integer, a next_cursor string for the next poll, and an as_of timestamp indicating data freshness.
