## 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 receipts-index-row-lookup-5d2612a1
```

Example prompt: Pull the Receipts Index row for check ID NB-CZ-GROK-1 and tell me whether my business was mentioned by Grok when a buyer asked 'Who is the best AI visibility service?' — and list any competitors that were named instead.

## When to prefer this

Use this endpoint when you need the raw, dated evidence of whether a specific business was mentioned (or not) by a named AI engine for a fixed buyer question — especially for auditing AI search visibility, tracking brand mentions over time, or doing competitive analysis on which businesses AI engines recommend in US local markets. Prefer this over general web search or SEO tools when you want structured, reproducible, timestamped AI recommendation data in CSV format keyed by a specific check ID.

## Known failure modes

- Row ID not found — returns empty or 404 if the row_id does not exist in the index
- Payment not processed — x402 payment required for paid rows; unpaid requests may return a 402 with payment details
- Malformed row_id — invalid format returns an error
- Free tier limit — only free/sample rows accessible without payment; paid rows require 0.27 USDC per call
- Network timeout — API may be slow or unavailable under load

## How this service works

Dated rows of which US local businesses AI engines name for fixed buyer questions. Free index and sample; paid rows over x402. Remote MCP at /mcp.

## Output

A single CSV row containing: the UTC date of the AI engine run, a check ID, the business name tested, its niche and market, the AI engine used, the prompt variant asked, the run number, a boolean for whether the business was mentioned, a semicolon-separated list of competitors that were named, sources cited by the engine, the run channel, and any flags (e.g. clean).
