What does each phone number finder result include?

A business name, the phone number in both a display format and the +1 dialer format, the website, the full address, the category, the star rating, and the review count. It is enough to build a call list or a CRM import without a second call.

Where do the business phone numbers come from?

The public business listing on Google. It is the main line each business publishes for itself, the same number anyone sees on the results page.

How many businesses can one phone number search return?

You search a category and a city and page for more, paying 1 credit per business returned. A single dentists in Miami query returned 20 businesses, and a search that returns none is free.

Is there a free phone number finder API?

CrustAPI includes 3,000 free credits every month with no credit card, and credits never expire. That covers a real call list for local outreach or CRM enrichment.

Phone number finder API

The phone number finder API pulls business phone numbers in bulk from a category and a city. Search dentists in Miami and get the name, phone, website, and address for every listing.

PULLED LIVE FROM THE API, JULY 20, 2026

One request, real response

# one credit per business returned; zero results cost nothing; phones unmasked in the API response curl "https://crustapi.com/v1/search?type=maps&q=dentists+in+Miami,+FL" -H "x-api-key: YOUR_KEY"

The API returns clean JSON, and the same rows are one click away as CSV, so the phone list drops straight into Sheets or a dialer:

name,phone,phoneUnformatted,address,category "Relax and Smile Dental Care","(786) 983-48••","+178698348••","271 NE 2nd St, Miami, FL 33132","Dentist" "Midtown Dental Miami","(305) 598-60••","+130559860••","3915 Biscayne Blvd Unit 306, Miami, FL 33137","Dentist"

Change the query to any category and city. This one search returned 20 businesses, each with a phone number in both a display format and the +1 dialer format.

WHAT EVERY BUSINESS INCLUDES

The full record, ready to use

Every business comes complete, so you build a call list or a CRM import with no second call. The same record as CSV, ready for Sheets or a database:

name,phone,phoneUnformatted,website,address,category,rating,reviews "Relax and Smile Dental Care","(786) 983-48••","+178698348••","https://www.relaxandsmile.com/","271 NE 2nd St, Miami, FL 33132","Dentist",4.9,904

Or the same record as JSON:

// the first business in full { "title": "Relax and Smile Dental Care", "phone": "(786) 983-48••", "phoneUnformatted": "+178698348••", "website": "https://www.relaxandsmile.com/", "address": "271 NE 2nd St, Miami, FL 33132", "city": "Miami", "state": "Florida", "postalCode": "33132", "categoryName": "Dentist", "totalScore": 4.9, "reviewsCount": 904 }

The phoneUnformatted field is the E.164 number, so it loads into a dialer or an SMS tool with no cleanup, while phone keeps the display format a person expects to read.

HOW IT COMPARES

vs a bought lead list

A static list you buy ages the day it lands. This pulls the phone numbers live each time you run the search.

	A bought lead list	CrustAPI phone finder
Billing unit	Per list or per contact, paid upfront	Per business returned; zero results free
Phone number	Can be stale by the time you call	The number each business lists, pulled live
Extra fields	Varies by seller	Website, full address, category, rating, and review count
Free tier	A sample, or none	3,000 credits / month, no card
Credits expiry	One-time purchase, no reuse	Never expire
Storing the data	Varies by seller	No storage limits. Keep it, export it, build on it

PRICING

One credit per business

Prepaid packs, and credits never expire: 25k for $49 · 100k for $149 · 500k for $549 · 2.5M for $1,999 · up to 250M, all self-serve, ex-tax. A search that returns 20 businesses costs 20 credits; a search that returns none costs nothing.

THE DIFFERENCE YOU SEE

A phone number on every result

Each business carries the phone number it lists, the website, the full address, and the category. In the dentists in Miami pull above that meant all 20 businesses came back with a number to call, from (786) 983-48•• for Relax and Smile Dental Care to (305) 598-60•• for Midtown Dental Miami, so a call list is built from the first response, not stitched together from many.

FAIR PLAY

When a licensed contact database is the better pick: you need personal cell numbers, direct-dial extensions for named people, or consumer phone numbers. This returns the public business phone each company lists on Google, which is the main line for the business, not a personal or direct number. That is what most cold-calling, local outreach, and CRM enrichment needs, but it is not a person-level contact database.
