## 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 answerpool-federal-rules-watch-feed-02b3e277 -d '<json body>'
```

Example prompt: Check the federal rules watch feed for any new rules or proposed rules published since 2026-08-01 and tell me what agencies have put out significant rulemakings.

## When to prefer this

Choose this endpoint when you need to continuously monitor the Federal Register for newly published rules and proposed rules in a scheduled or event-driven agent workflow. It is purpose-built for polling loops — you only need to retain the next_since cursor between calls. Prefer this over a full-text search endpoint when you want an incremental, chronological feed of all new rulemaking activity rather than searching by keyword or agency. Ideal for compliance automation, regulatory alerting, and daily digest pipelines.

## Known failure modes

- Invalid or malformed ISO date cursor returns a 400 error
- Date cursor set too far in the past may return large result sets or be rate-limited
- No new documents since the cursor returns an empty documents array with count 0
- Network or upstream Federal Register data availability issues may cause 503 or timeout
- Missing required since parameter results in an error response

## How this service works

AnswerPool turns SEC EDGAR, the Federal Register, USAspending, NIH, BLS and OpenAlex into structured JSON answers that AI agents and developers fetch in one call. 69 endpoints free, no account; derived analyses $0.02–$0.05 per call by card credits or USDC (x402). MCP server, full provenance.

## Output

A JSON object containing the as_of timestamp, a count of matching documents, an array of rule documents (each with URL, type, flags, title, action, topics, abstract, agencies, docket IDs, CFR references, effective date, comment close date, days to effective, significance indicator, and document number), a next_since cursor for the next poll, and a total_matching count.
