## 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-daily-ai-mention-rows-3652c7a5

Example prompt: Pull the Receipts Index data for September 1, 2026 — I want to see which US businesses AI engines like Grok and ChatGPT named in response to fixed buyer questions that day, including whether my competitors were mentioned.

## When to prefer this

Choose this endpoint when you need raw, dated, per-run evidence of which businesses AI engines recommended in response to fixed buyer questions — particularly for auditing AI visibility, building time-series brand-mention datasets, or competitive intelligence in the US local business market. Prefer this over social listening or SEO rank-tracking tools when the specific question is 'what did an AI engine say, on this exact date, when a buyer asked this question?'

## Known failure modes

- Date not yet indexed — data may not be available for future or very recent dates
- Invalid date format in path parameter returns an error
- No data rows for a date where no runs were conducted (empty CSV)
- Payment failure via x402 if USDC balance is insufficient ($1.81 per call)
- Rate limiting or authentication errors if access credentials are invalid
