SpecStream reads the live web for each row you send. Ask for the usual fields, or for anything you can describe in words, such as "offers same day delivery" or "lists SOC 2 on its site", and each row is checked on its own pages. Every value comes back with the URL of the page it was read on and the time it was read, so a value your CRM will overwrite can be checked first. In Deep Search, `get_find_decisions` returns each condition's answer for a row with its reason, the value, the source and the time. ### A filled field is not a right field The public benchmarks show the gap. On the Openbenchmarks board of 282 companies, CompanyEnrich returned 95.5% of the fields but 74.7% of the fields it returned were right. People Data Labs reached 89.0% enrichment success and Apollo 92.6% field accuracy. In Firecrawl's run of 200 US companies, employee count averaged 57% across providers. A database fills the cell either way. SpecStream delivers a value with the page that states it, and a row that a page contradicts is not charged. For a whole company record from many sites, see the [company data API](https://specstream.ai/company-data-api?utm_source=alternatives&utm_campaign=data-enrichment-api) prices. ### You pay per delivered row, with no monthly plan to size A row costs 5¢ with up to 5 facts, 15¢ with up to 15 facts and one set of related records, and $1 for a deep row. An email adds 5¢ and a phone 15¢. Importing, mapping and exporting are free, and a row SpecStream can't find costs nothing. The database APIs sell a monthly allowance. CompanyEnrich is cheaper per lookup, at $0.0098 a credit on Starter, for the fields it holds. People Data Labs Pro is $100 a month for 1,000 records. SpecStream has no allowance to use up. ### Enriched rows stay up to date Save the request and it reruns hourly to yearly. A changed or new row costs half its rate and an unchanged row costs 1¢, so rechecking 1,000 companies that did not change costs $10. Each row comes back labeled changed, unchanged or no longer matching, and a linked sheet is checked every day for new rows. ### Search, page reading and rows on one key The same key runs the Search API, the most accurate web search API in the world: 97.9 F-score on all 1,000 SimpleQA Verified questions (978 correct) and 64.0 item F1 on all 200 WideSearch tasks, shown on the [benchmarks](https://specstream.ai/benchmarks?utm_source=alternatives&utm_campaign=data-enrichment-api) page. Search is $5 per 1,000 searches of up to 10 results, and the Extract API reads pages at $0.80 per 1,000. ## Other data enrichment APIs ### Apollo A sales database with an API, at $0.0196 a credit on the Openbenchmarks price table, where it scored 92.6% field accuracy and 88.6% enrichment success.

SpecStream has no monthly plan to buy: a company row costs 5¢ when it is delivered. ## How to start Import the list or link the sheet, pick the rows and the fields to add, and approve the most the run can cost. SpecStream fills empty cells only, and values you imported stay labeled as yours. New accounts get $10 of credit, no card, which is up to 200 rows at 5¢. 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": "For the companies at stripe.com, gusto.com and figma.com: the headquarters city, employee count, founded year, industry and LinkedIn page", "count": 3}' ``` On an account, your agent uses the MCP server at `https://api.specstream.ai/mcp` with OAuth or an API key, and your team uses the workspace, from the same balance. The [MCP docs](https://specstream.ai/docs/mcp?utm_source=alternatives&utm_campaign=data-enrichment-api) list the tools. ## Frequently asked questions ### What is a data enrichment API?
