## 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 serp402-google-maps-reviews-17fc767c -d '<json body>'
```

Example prompt: Pull the 20 most recent English-language Google Maps reviews for the place with place_id ChIJN1t_tDeuEmsRUsoyG83frY4 and sort them by newest first.

## When to prefer this

Use this endpoint when you need structured, paginated Google Maps review data — including reviewer metadata, ratings, and topic filters — without setting up a Google API key or account. It is ideal for agents that need pay-per-call, zero-subscription access to review data for reputation monitoring, sentiment analysis, or business intelligence pipelines.

## Known failure modes

- Invalid or missing place_id and data_id — endpoint requires at least one
- Simultaneous use of query and topic_id parameters — these are mutually exclusive
- Place not found or no reviews available for the given ID
- num out of range (must be 1–20)
- Invalid language code causing unexpected results
- Rate limits or temporary scraping blocks returning empty or error responses
- Stale data if Google Maps source has been updated since last scrape
