## The ideas

- **[A local lead list for web agencies](https://apiforagents.dev/platforms/google_maps/search-api).** For agencies that build websites. It searches a trade in a city and keeps only places without a website. Uses search.

- **[A reputation dashboard for chains](https://apiforagents.dev/platforms/google_maps/places-api).** For multi-location brands. It reads each location's card and charts rating and review count from the stored series, which is free. Uses places and history.
- **[A competitor review comparison](https://apiforagents.dev/platforms/google_maps/search-api).** For local businesses. It reads reviews of nearby rivals and lists what customers praise and complain about. Uses search and reviews.
- **[A local market map](https://apiforagents.dev/platforms/google_maps/search-api).** For founders and analysts. It searches a category in a city and maps how many places there are and how they rate. Uses search.
- **[A site selection helper](https://apiforagents.dev/platforms/google_maps/search-api).** For retailers choosing a spot. It reads nearby places with ratings and popular times to see how busy an area is. Uses search and places.
- **[A busy times helper](https://apiforagents.dev/platforms/google_maps/places-api).** For people planning a visit. It reads popular times on a place's card to suggest a quieter hour. Uses places.
- **[A local directory builder](https://apiforagents.dev/platforms/google_maps/search-api).** For directory and city guide sites. It searches a category and keeps each place's address, hours, contact and socials. Uses search and places.
- **[A low-rating alert](https://apiforagents.dev/platforms/google_maps/reviews-api).** For franchise and operations teams. It reads the lowest-rated reviews first and sends new ones to the location manager. Uses reviews.
- **[A location listing audit](https://apiforagents.dev/platforms/google_maps/places-api).** For brands with many branches. It checks that hours and contact details match across every location. Uses places.
- **[A sales territory planner](https://apiforagents.dev/platforms/google_maps/search-api).** For field sales teams. It searches a target category with a minimum rating in each area of a territory. Uses search.

## How to start

1. Sign up. An agent registers itself with one POST and starts with $0.10 of free credit; a person can sign up on the site instead.
2. Quote the first call for free: send the search request with "estimateOnly": true and read the price before anything is spent.
3. Run the same call with "maxUsd" set as a ceiling, and keep the rows it returns.
4. Schedule it: repeat the call daily or weekly, and read the stored series with history, which is free.

## Operations used

- [Google Maps Search API](https://apiforagents.dev/platforms/google_maps/search-api): $0.000225 per record. Places for a keyword in a location.
- [Google Maps Places API](https://apiforagents.dev/platforms/google_maps/places-api): $0.000225 per record. Full cards for up to ten places by Maps URL (place id or cid).
- [Google Maps Reviews API](https://apiforagents.dev/platforms/google_maps/reviews-api): $0.000225 per record. Reviews for up to ten places.

## Questions

### How do I get place URLs for reviews?

Run search first. Every hit is a full place card, and its Maps URL is what places and reviews take.

### Do I need a Google Maps account to build these?

No. The API reads public data and never asks for your login, password or cookie.

### What does a run cost?

Google Maps records are priced from $0.000225 per record. A call can carry a minimum, so send it first with "estimateOnly": true. The quote is free and is the most the call can cost.

### Can an AI agent build and run these on its own?

Yes. It signs itself up with one call and gets $0.10 free, quotes each call before it spends, and pays from a prepaid balance. "maxUsd" caps every call, and only a person can add money.

## Why API for Agents

- One key for 26 platforms: social, commerce, jobs, places, search and contacts, with one request shape and one response shape.
- A free quote before any spend: add "estimateOnly": true to any call and see the most it can cost.
- Pay per record in US dollars. No subscription, nothing expires, top-ups from $5.
- $0.10 free to try, no card. An AI agent can sign itself up in one request; a person claims it later.
- Measured, not estimated: every answer says when each row was measured, whether it was fresh or a recent capture, and how sure to be of each field.
- Partial success is success: anything that could not be fetched is named with a reason, and the charge settles to what came back, never above the quote.
- Typed fields that keep their names whichever source answered, and a details object last with everything else the source sent, under our own field names.
- Try any endpoint in the playground and download the answer as CSV or JSON.

## Start

The playground runs any endpoint by hand: pick a platform and what you want from it, fill a short form named in plain words (or press Use sample input), see the free quote on the Run button, run it, then read the answer as a table or JSON and download it as CSV or JSON. The same call is written out as cURL, Python and Node while you type. Open it at https://apiforagents.dev/dashboard/run (sign in first).
