## 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 edgar-auditor-change-digest-llm-brief-3f3dc2b1
```

Example prompt: Give me an LLM-written brief on the most notable auditor change filings on SEC EDGAR from the past 30 days — which companies switched auditors and why does it matter?

## When to prefer this

Use this endpoint when you need a fast, human-readable narrative summary of SEC EDGAR auditor change filings rather than raw filing data. Ideal for compliance monitoring, investment due diligence signals, or financial news digests where the goal is understanding patterns and notable events — not processing individual filings programmatically.

## Known failure modes

- No auditor change filings found in the specified window — brief may be empty or minimal
- Invalid date-time format for 'since' parameter returns a 400 error
- LLM generation failure falls back to template-based output (reflected in generatedBy field)
- Payment of $0.25 USDC not completed results in 402 Payment Required
- Very large windows with many filings may result in truncated or high-level summaries

## How this service works

An LLM-written digest of the most notable auditor / accountant changes filings in the window.

## Output

A structured object containing: a 'brief' field with a natural-language narrative summarizing the most notable auditor/accountant change filings; 'generatedBy' indicating whether an LLM or template produced it; and 'basedOnChanges' as an integer count of the underlying SEC filings analyzed.
