When the field you need is not in that dataset, the call returns nothing for it. SpecStream reads the request your product, agent or team has: the records, the fields to bring back and the conditions each row must meet. Ask for the head of sales and a work email, or for a fact no vendor sells, such as whether a company publishes a sustainability report, and each row is read from that company's own pages. Bring the list you have: a CSV, Excel file, Google Sheet or Airtable base of up to 20,000 rows. Importing is free. SpecStream matches each row to one identity, shows any namesakes beside their evidence, and fills only the empty cells. Your own values are never overwritten. ### One price per row, known before the run A row costs 5¢ with up to 5 facts, 15¢ with up to 15 facts and one set of related records, and $1 with no limit. An email adds 5¢ and a phone 15¢. So 1,000 companies with 5 facts cost $50, and with a work email for one person at each, $100. The rate is the same on every plan. The credit APIs price the same job in their own units. On People Data Labs, 1,000 company records are the $100 Company Pro plan. On Coresignal, 1,000 full company records are 20,000 credits, more than the $199 Starter plan holds, so the job needs Pro at $499 a month for 35,000 credits. On SpecStream every request gets a quote of the most it can cost, good for 30 minutes, nothing runs until that maximum is approved, and what the run does not use goes back to your balance. ### Each value with the page it was read on Each value in a SpecStream row carries the URL of the page it was read on and the time it was read. `get_find_decisions` returns each condition's answer for a row with its reason, the value, the source and the time. A row that a page contradicts is not charged. ### Enriched rows stay up to date Save a 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 companies that did not change costs $10. The changes reach HubSpot, Salesforce, Pipedrive, Attio, Sheets, Slack or a signed webhook. ### Filings we already hold, and measured search SpecStream reads public company records every day. In the week of November 9, 2026, 177 operating companies filed a Form D reporting $10.00 billion sold, and each one is a row on [specstream.ai/data/form-d](https://specstream.ai/data/form-d?utm_source=alternatives&utm_campaign=best-data-enrichment-apis). The same key runs the Search API, the most accurate web search API in the world: 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 scores 0.908 F1 on WCXB. The scores and the method are on the [benchmarks](https://specstream.ai/benchmarks?utm_source=alternatives&utm_campaign=best-data-enrichment-apis) page. ## Other data enrichment APIs ### Reverse Contact A people and company data API with flat monthly plans. Max is $699 a month for unlimited enrichment from an email, a name or a domain, and emails, phones and live refreshes still run on credits. SpecStream has no monthly plan to size: a row costs 5¢, 15¢ or $1 when it is delivered, with any field your request names. ### Autobound A signal data API: enrich costs 2 credits per signal, and packs run from $19 for 1,900 credits to $4,999 for 1,249,750. SpecStream returns the signal as a field on the row, with the page it was read on, and keeps it up to date at 1¢ for a row that did not change. ### Clearbit On Nov 12, 2026, clearbit.com is headed "Clearbit has joined HubSpot!", with a customer login and no price. On SpecStream you import the list you enriched with Clearbit, up to 20,000 rows, and each row is filled in or checked: a match pays its rate and a row that does not match costs 5¢. ## How to start Import the list you have, or write the records and fields you need in plain words. Sign up and you get $10 of credit, no card. At 5¢ a row, that is up to 200 rows. Or send the request from code. This call spends nothing: the `402` reply shows how SpecStream read the request, the columns and the most it can cost. ``` curl -i https://api.specstream.ai/v1/agent/lists \ -H "Content-Type: application/json" \ -d '{"request": "stripe.com, notion.so and linear.app, with the headcount, the headquarters city, the head of sales and a work email", "count": 3}' ``` Approve that maximum by card through Stripe's Link agent wallet, or in USDC on Base, Arbitrum or Polygon, and you pay for the rows found. On an account, your agent uses the MCP server at `https://api.specstream.ai/mcp` and your team uses the workspace, from the same balance. ## Frequently asked questions ### What is a data enrichment API? A data enrichment API takes a record you have, such as a company domain or a person's name, and returns the fields you are missing: headcount, industry, location, the people, an email or a phone. SpecStream fills any field you can describe at 5¢, 15¢ or $1 a delivered row, from the live web, with the source URL and read time on every value. ### What is the best data enrichment API in 2026? SpecStream, at 5¢, 15¢ or $1 a delivered row. You name the records and the fields in plain words, approve the most the run can cost, and get one typed row per record, filled from the live web rather than one vendor's dataset. The rows reach your product through the API and MCP, or your CRM and sheet with no code, and a saved request keeps them up to date. ### How much does a data enrichment API cost? SpecStream costs 5¢, 15¢ or $1 a delivered row, plus 5¢ for an email and 15¢ for a phone, with no monthly minimum. People Data Labs Person Pro starts at $98 a month for 350 credits. Coresignal runs from $49 a month for 2,500 credits, at 20 credits a full company record. Enrich Layer packs start at $10 for 100 credits. Bitscale Growth is $349 a month, and its REST API is on Enterprise from $15K a year. ### Is there a free data enrichment API?

People Data Labs gives up to 100 credits a month with no contact data, Coresignal a 7 day trial with 2,000 credits, Crustdata $20 in credits and Bitscale 200 credits. ### Do I pay when a record has no match? On SpecStream, an imported row that does not match costs 5¢ for the check, and a run that finds nothing costs nothing. People Data Labs bills enrichment only on a match, Crustdata does not charge for an empty search, and Bitscale spends credits only when a provider returns a valid result. ### Does SpecStream have an API and an MCP server? Yes. Deep Search returns enriched rows at 5¢, 15¢ or $1, the Search API costs $5 per 1,000 searches of up to 10 results, and the Extract API costs $0.80 per 1,000 pages. All three run on one key through the REST API, the Python and TypeScript SDKs, the CLI, A2A and the MCP server at `https://api.specstream.ai/mcp`. ## Sources SpecStream wrote this page.
