Company data API: SpecStream, People Data Labs, Coresignal and more compared
Most company data APIs sell records from a database they hold, by credits or by contract. SpecStream is the live web data engine for teams and agents. Send the companies you want in plain words, with any condition they must meet, and Deep Search returns structured rows checked on the live web, with the source URL and read time of every value, at 5¢, 15¢ or $1 a delivered row. You approve the most a call can cost before it runs. SpecStream leads two public benchmarks: WideSearch, at 60.9 on the low-cost model, where the best other API scores 57.6 even on the larger model, and SimpleQA Verified, at 99. The scores and their sources are on benchmarks.
New accounts get $10 of credit for their first 30 days, no card.

Why data teams choose SpecStream for company data
Any condition you can describe
A company database answers with the fields it already keeps. SpecStream reads your request into the conditions every company must meet and the facts to bring back, then checks each one on the live web: packaging suppliers in Portugal with more than 50 employees and a published product catalog, with their contact email, is one request.
Every value comes back with its source URL and read time, so your pipeline can store where each fact came from.
A price per delivered row
A row costs 5¢ for up to 5 facts, 15¢ for up to 15 facts and one set of related records, and $1 for a deep row, plus 5¢ for an email and 15¢ for a phone. The rate is the same on every plan. Duplicates, rows you already own and rows a page contradicts are not charged, and a call that finds nothing costs nothing.
Each call is quoted first. Nothing runs until the maximum is approved, and there are no automatic overages.
Public records and signals, read every morning
SpecStream holds every company that filed a Form D since 2023 with its filing history, nearly 2 million US nonprofits, every US bank failure since 1934, and open federal contracts and grants, at specstream.ai/data. Funding rounds, new executives and layoffs are at specstream.ai/signals.
Set any request to rerun from hourly to yearly. A changed or new row costs half its rate, and an unchanged row costs 1¢. Rows go to HubSpot, Salesforce and Google Sheets, or to your own systems through a signed webhook.
