## Each source, in order

- **[1. LinkedIn people search](https://apiforagents.dev/platforms/linkedin/people-search-api).** Search one company's people, or all of LinkedIn, by current title, seniority, function, location, industry, company size and tenure. Flags for people who recently changed jobs or recently posted narrow the list to people worth a message now. It returns public profile data, not contact details.
- **[2. Work email and phone](https://apiforagents.dev/platforms/contacts/work-email-and-phone-api).** Give up to ten LinkedIn /in/ handles and get each person's work email and mobile number. Ask for email only when that is enough, add verify to check each address before it counts, and ask for another source when a value is wrong. It is the one source here that is not read from public pages; it is priced per call, and a part you already own is free.
- **[3. Google Maps search](https://apiforagents.dev/platforms/google_maps/search-api).** A keyword in a location returns full place cards with the phone, website, emails and socials a business lists, plus rating and hours. The website filter keeps only places without a website, or only those with one. Best for businesses you would find on a street, not by job title.
- **[4. LinkedIn company search](https://apiforagents.dev/platforms/linkedin/company-search-api).** Search companies by keyword with location, headcount band and industry filters. Each row carries industry, size bucket, employee count, followers, website, HQ, founding year and specialities. Pass the company handles into people search to find who works there.
- **[5. LinkedIn jobs](https://apiforagents.dev/platforms/linkedin/jobs-api).** A company hiring for a role may be about to buy for it. Search listings by title with location, company, workplace, experience level and posted-within filters; rows carry the company name, salary text, listing date and apply URL.
- **[6. Indeed job search](https://apiforagents.dev/platforms/indeed/jobs-api).** Every hit is a full posting with the company's industry and size, salary range, skills and hiring signals such as urgent hire and employer response rate. It searches 23 country sites. The only workplace filter is remote.
- **[7. Yelp search](https://apiforagents.dev/platforms/yelp/search-api).** A place and keyword with Yelp's own sort, price levels and feature filters; every hit is a full profile with phone, website and rating. Use it beside Google Maps when your buyers are restaurants or local services.

## How to choose

1. Selling to roles inside companies: LinkedIn company search to build the account list, people search to find the person, then the contacts lookup for the people you keep.
2. Selling to local businesses: Google Maps search first, Yelp as a second source.
3. Timing: job listings on LinkedIn and Indeed show who is growing a team right now.
4. Reveal last. Qualify people before you buy their contact details, and ask for email only when a phone is not needed.

> **Verdict** For most B2B teams: LinkedIn people search to find, the contacts lookup to reach, Google Maps search for local accounts.

## Questions

### Where can I get B2B leads with email addresses?

Find the person with LinkedIn people search, then pass their /in/ handle to the contacts lookup for a work email and mobile number. Google Maps place cards also carry the emails a business lists publicly.

### Can I find businesses that have no website?

Yes. Google Maps search takes a website filter: "without" keeps only places that list no website.

### What if an email or number is wrong?

Reveal again with tryAnotherSource for that part only. It is bought again from a different source, at that part's price.

### Do I need a LinkedIn account?

No. The LinkedIn operations read public data and never ask for a login, cookie or session.

### How much does a lead cost?

Each step has its own price: LinkedIn people search $0.004 per record, Google Maps search $0.000225 per record, and the contacts lookup is quoted per call, billed per person and per part. Quote first with "estimateOnly": true.
