[ Book a call ](/book)[ See case studies ](/case-studies) 05 ## Questions people ask Which is cheaper per email, AI Ark or BlitzAPI? It depends on volume. AI Ark charges 1 credit per verified email found, about 1 cent at its $49 entry package. BlitzAPI Start is $99 a month flat for up to 200,000 records, and each email found counts as one record, so its cost per email falls the more of the cap you use. What happens when I run out? On BlitzAPI, calls pause at the fair-use cap until the next billing cycle or until you move up a plan, and unused records do not carry over. On AI Ark you can re-subscribe, which resets the billing cycle, or ask for a one-off top-up; unused credits roll over up to 2x the monthly allowance. Do AI Ark and BlitzAPI have free trials? AI Ark's Free plan gives 100 credits a month with no card. BlitzAPI gives 1,000 free records to try, with no card, at 5 requests a second per endpoint; phone lookups are not part of the trial. Can I resell the data or build a product on it? Not on the standard plans. BlitzAPI includes a reseller agreement only with Build Your Infra (from $999 a month) and requires Blitz Embedded (from $2,000 a month, annual) when people outside your company use Blitz-powered features. AI Ark's terms limit exported data to internal outreach and ban resale or redistribution. Do AI Ark and BlitzAPI have MCP servers? Yes. BlitzAPI's is at api.blitz-api.ai/mcp with OAuth or the x-api-key header, and lists 24 tools. AI Ark's is at api.ai-ark.com/v1/mcp, with the API key in the URL. ## Related [![](/_astro/ai-ark.BE60pifs_ZPFRIO.webp)AI Ark API review](/tool-directory/sourcing/ai-ark)[![](/_astro/blitz-api.Bf9EP17n_QOEMP.webp)BlitzAPI API review](/tool-directory/sourcing/blitz-api)[![](/_astro/ai-ark.BE60pifs_ZPFRIO.webp)![](/_astro/apollo.DNg6-7d3.svg)AI Ark vs Apollo](/tool-directory/compare/ai-ark-vs-apollo)[![](/_astro/ai-ark.BE60pifs_ZPFRIO.webp)![](/_astro/explorium.D7Wqtnux.svg)AI Ark vs Explorium](/tool-directory/compare/ai-ark-vs-explorium)[![](/_astro/ai-ark.BE60pifs_ZPFRIO.webp)![](/_astro/findymail.BKowYsnX_9Tf99.webp)AI Ark vs Findymail](/tool-directory/compare/ai-ark-vs-findymail)[![](/_astro/ai-ark.BE60pifs_ZPFRIO.webp)![](/_astro/people-data-labs.mXDEg2jz_Z86udK.webp)AI Ark vs People Data Labs](/tool-directory/compare/ai-ark-vs-people-data-labs) Read from [ai-ark.com/pricing](https://ai-ark.com/pricing), [blitz-api.ai/pricing](https://blitz-api.ai/pricing) and each tool's API docs.
