## 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-filing-change-signal-49225238 -d '<json body>'
```

Example prompt: Check if Acme Capital LLC has had any new SEC filings since January 1, 2026 and tell me whether there's a new relevant filing I should know about.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call polling signal for SEC filing changes — especially Form D fundraising triggers — without maintaining API keys or a subscription. Ideal for autonomous agents that need to periodically check for new filings and receive a structured decision signal with a cursor for the next poll. Prefer over manual EDGAR scraping or subscription-based compliance services when cost-per-call economics and agentic polling patterns are required.

## Known failure modes

- Unknown or unresolvable entity returns empty filings array with NO_NEW_FILING decision
- Invalid or future since timestamp may return an error or empty result
- Malformed request body results in 400-level HTTP error
- Payment failure (x402) if USDC balance is insufficient
- Rate limiting or service unavailability returns 5xx error

## How this service works

Check whether a company filed a new SEC 8-K, 10-Q, or 10-K after a timestamp. Accepts a ticker or CIK and returns a compact filing decision, accession links, and a next-check cursor; no materiality opinion or investment advice.

## Output

A JSON object containing a decision field (e.g. NEW_RELEVANT_FILING or NO_NEW_FILING), a list of new filings found, a filing count, a next_since cursor timestamp for the next poll, a request ID, and a path to premium evidence if available.
