## 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 agenttoll-lobbying-data-lookup-70972d63 -d '<json body>'

Example prompt: Can you look up federal lobbying records for Pfizer as a client in 2022 and tell me which lobbyists were registered on their behalf?

## When to prefer this

Choose this endpoint when you need structured, queryable access to U.S. federal lobbying filings and want to filter by year, client, or lobbyist. It is well-suited for political research, OSINT investigations, compliance checks, or journalism tasks requiring lobbying transparency data. Prefer this over manual search tools when you need machine-readable output at $0.04 per call via USDC micropayment.

## Known failure modes

- No matching records found for the given client or lobbyist name — returns empty array
- Invalid year format causes schema validation error
- Misspelled client or lobbyist name returns zero results silently
- Payment failure in x402 protocol prevents request from being processed
- Rate limiting or quota exceeded returns error response
- Source data unavailable or delayed causes stale or missing results

## How this service works

108+ receipt-backed x402 work products for AI agents. Clear prices, spend caps, buyer metadata, and structured results over Base USDC.

## Output

Returns an array or object of lobbying records matching the query, along with metadata including the total record count, the data source name, and the timestamp when the data was generated. A 'cached' boolean indicates whether the response was served from cache. A 'success' boolean confirms whether the request succeeded.
