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 toll-road-sec-filing-changes-detector-01aa45fc
```

Example prompt: Check Toll Road for any new or removed SEC filings for Apple — their CIK is 320193 — and tell me what changed since the last snapshot.

## When to prefer this

Choose this endpoint when you need to detect incremental changes (additions and removals) to a specific company's SEC filings relative to a previously recorded snapshot, rather than fetching the full filing list from scratch. It is especially useful for ongoing monitoring workflows where you want to be alerted only when something changes, and it saves you from parsing all of EDGAR yourself.

## Known failure modes

- Invalid or non-existent CIK returns an error or empty result
- First call for a CIK establishes a baseline with no diff available (baseline: true)
- SEC EDGAR unavailable causes upstream fetch failure
- Rate limiting or payment failure returns 402 or 429 status
- Malformed CIK format may cause query rejection

## How this service works

Detect SEC filing additions and removals since Toll Road's last observed company snapshot.

## Output

Returns a structured object indicating whether this is a baseline observation, the timestamp of the current and previous observations, the total current filing count, the company metadata, and a changes object detailing which filings were added or removed since the last snapshot.
