## 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 congress-bills-brief-llm-digest-e0065c6f
```

Example prompt: Give me an LLM-written digest of the most consequential things Congress has done in the last 30 days — I want the key bills and actions summarized in plain language.

## When to prefer this

Use this endpoint when you need a human-readable, narrative-style summary of recent US congressional activity rather than raw bill data. Ideal for agents providing political news briefings, legislative monitoring, or policy awareness — especially when the user wants a concise digest rather than structured bill records. Prefer over raw legislative data APIs when the goal is readability and synthesis.

## Known failure modes

- Invalid or unparseable 'since' datetime format returns a 400 error
- No congressional activity found in the window may return an empty or minimal brief
- LLM generation failure may fall back to template-based output (generatedBy: 'template')
- Service unavailable or Railway platform downtime returns 5xx
- Payment not accepted or insufficient funds returns 402

## How this service works

An LLM-written digest of the most consequential congressional actions in the window.

## Output

A JSON object containing a 'brief' field with an LLM-written narrative paragraph summarizing the most consequential congressional bills and actions in the requested window, a 'generatedBy' field indicating whether an LLM or template produced it, and a 'basedOnChanges' integer indicating how many congressional actions were analyzed.
