People data API in 2026

People found by what they do, from the live web

A people database answers with the profiles and fields it already keeps, and a person it does not match returns a 404. A SpecStream request is the whole job, written once: "Heads of engineering at Series A and B developer tool companies in the United States, with the company, the city, the last funding round and a work email for each".

SpecStream reads the request back as parts you can edit, the conditions every row must meet and the facts to bring back, then searches the live web, reads each page and joins what it finds into one record per person. A person who fails one condition is not delivered and not billed.

A row costs 5¢, and a miss costs nothing

The rates are on pricing: 5¢ for a row with up to 5 facts, 15¢ for up to 15 facts and one set of related records, and $1 for a deep row with no limit. An email adds 5¢ and a phone 15¢. 1,000 people with 5 facts and a work email cost $100.

At People Data Labs' starting plan, $98 buys 350 person credits, 28¢ each. On SpecStream, duplicates, rows you already own and rows a page contradicts are not charged, and a run that finds nothing costs nothing.

The list you already have, filled in

Import a CSV, Excel file, Google Sheet or Airtable base of up to 20,000 people. SpecStream fills in or checks each row and matches it to one identity, with any namesakes shown beside their evidence, so no namesake is chosen for you. Import is free. A row that matches pays its rate, and a row that does not costs 5¢.

Your agent spends under a maximum you approved

Every request gets a quote of the most it can cost, good for 30 minutes. Nothing runs until you approve it, the charge never goes past that amount, and what the run does not use goes back to your balance. An API key carries its own limits: total, per run and monthly. Agents connect to https://api.specstream.ai/mcp with OAuth or an API key, and people and agents spend from one balance.

People records that stay up to date

Save the request and it reruns hourly to yearly. Each row comes back labeled changed, unchanged or no longer matching. A changed or new row costs half its rate (3¢, 8¢ or 50¢) and an unchanged row costs 1¢, so rechecking 1,000 people who did not change costs $10. New executives, funding rounds and layoffs are at specstream.ai/signals.

The most accurate web search API, on the same key

The Search API answers one question from the live web for $5 per 1,000 searches of up to 10 results, and $1 per 1,000 on the fast tier. It scores 97.9 F-score on all 1,000 official SimpleQA Verified questions (978 correct), and 64.0 item F1 and 43.4 row F1 on all 200 official WideSearch tasks. The Extract API reads pages for $0.80 per 1,000 and scores 0.908 F1 on WCXB. Scores and method are on benchmarks.

SpecStream

The live web data engine for teams and agents. One request in plain words, through the API or MCP, returns every person that meets your conditions as a row, at 5¢, 15¢ or $1 a delivered row, plus 5¢ for an email and 15¢ for a phone. New accounts get $10 of credit, no card.

Coresignal

Employee data sold in monthly credit plans from $49 a month, with a full employee record at 20 credits and a $1,000 a month tier at $0.007 a credit. SpecStream has no monthly allowance to size: each delivered row costs 5¢, 15¢ or $1 on every plan.

Enrich Layer

An enrichment API on monthly and annual plans, both a 12 month commitment with a fee for canceling early. SpecStream has no commitment: you pay for delivered rows from your balance, and a top-up never expires.

Apollo

A sales platform billed in credits that reset at the start of each billing cycle and do not roll over. On SpecStream a row costs the same on every plan, and the people come with the company facts your request names.
