## 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 agentrxi-since-cutoff-briefing-89a2d6e8
```

Example prompt: Brief me on everything that happened with OpenAI since April 1, 2024 — newest events first with dates and citations, and tell me what changed compared to before.

## When to prefer this

Choose this endpoint when an AI agent needs to bridge its knowledge cutoff gap on a specific topic — especially when citations and a sense of 'what changed' are required, not just raw search results. Prefer it over general web search tools when the user explicitly needs dated, chronological coverage from a specific point in time forward, with provenance.

## Known failure modes

- Missing required 'topic' or 'since' query parameter returns a 400-level error
- Dates in incorrect format (not YYYY-MM-DD) rejected
- Very obscure or ambiguous topics may yield sparse or no results
- Topics with no indexed activity after the given date return an empty or minimal briefing
- Rate limiting or payment failure returns 402 or 429 errors

## How this service works

Since-my-cutoff briefing: everything that happened on a topic after a given date (for models whose knowledge stops there), newest first with dates and citations, plus what changed versus the old state.

## Output

A structured briefing listing events on the requested topic after the given date, ordered newest-first, each entry annotated with its date and a citation. Includes a summary of what changed versus the prior state of the topic.
