We rank by the cheapest price per lookup among a provider's person enrichment endpoints, read live from the catalog. A cheaper lookup ranks higher. Some providers bill per call and some per person matched. One lookup returns at most one person, so the two prices compare, but a per-match provider charges nothing on a miss. Free endpoints are not ranked, because a zero price says nothing about coverage. The catalog does not publish a measured success rate for these endpoints, so this page does not rank by one and quotes none. Providers outside the looot catalog are not ranked. Company enrichment from a domain is ranked on its own page. ## Cheapest data enrichment API per 1,000 lookups On 2026-11-04 the cheapest data enrichment API in the looot catalog is Dropleads at $2.90 per 1,000 lookups ($0.0029 per lookup), then Hunter at $4.90 and Tomba at $8.90. The dearest, Lusha, costs $750.00 per 1,000 lookups. The ranking shows each provider's live price per lookup and per 1,000 lookups. On a list with many misses, a provider billed per match can cost less than a cheaper one billed per call. Phone numbers and verified emails often cost extra on top of the base lookup. Read the price for the fields you ask for before you run a long list.

An endpoint your code or agent calls with something you know about a person, such as an email or a LinkedIn URL, to get the rest back as structured data: name, title, employer, location and sometimes contact fields. ## What is the difference between a contact enrichment API and a lead enrichment API? None in the call itself. Both turn an identifier into a person record. Lead enrichment is the name sales teams use when the list is prospects. ## Is there a free data enrichment API? This page ranks priced endpoints. Several of them charge nothing when there is no match: Prospeo, Limadata, FullEnrich, People Data Labs and Lusha all say so in the catalog. ## What are the best Clearbit alternatives? Clearbit is not in the looot catalog, so this page does not rank it. The providers above enrich a person from an email, a LinkedIn URL or a name, and your agent calls any of them with one key. ## Which data enrichment API returns phone numbers? Prospeo, Lusha and Limadata can add a phone to the lookup at a higher charge. Tomba, Dropleads and Limadata also have a phone finder endpoint, shown as extras in the ranking. ## Can I enrich a person from only a name? Not reliably. Add the company name or domain. Dropleads, FullEnrich, Limadata, Lusha and People Data Labs take a name with a company. Hunter, Tomba and Datagma need an email or a LinkedIn profile. ## How does an agent call a data enrichment API? Paste the prompt on this page into your agent. It sets up looot, finds the person enrichment endpoints, checks the price and runs the cheapest one that takes your input. ## How do I enrich a whole CSV? Give your agent the file and the fields. It runs one lookup per row and reports the total cost. Prospeo and Dropleads also have bulk endpoints, shown as extras. ## Can I refresh enriched records every month? Re-running the lookups by hand works today. Refreshing on a timer needs scheduled runs, not available yet. ## Why does this page not show success rates? The catalog does not publish a measured success rate for these endpoints. Match rates also depend on your list, so run one batch of known rows and compare. ## Related pages - /best/b2b-data-api - /best/company-database-api - /best/lead-finder - /best/email-verification-api - /best/linkedin-api - /best/serp-api - /best/rank-tracker-api - /best/news-api - /best/tiktok-api - /best/reddit-api - /best/web-scraping-api - /best/web-search-api - /best/google-maps-scraper-api - /use-cases/data-enrichment - /use-cases/enrich-a-person - /use-cases/find-professional-emails - /recipes/build-a-clay-style-table - /recipes/ceo-emails-for-fintechs - /gtm ## Last reviewed 2026-11-03.
