If your real job is getting verified emails for a list you already have, start with the email-finding guide.

[ Book a call ](/book)[ See case studies ](/case-studies) 05 ## Questions people ask Is Attio a replacement for Apollo? Only for the CRM part. Attio holds and enriches records you already have, but it has no prospect database to search. Apollo's database covers over 240 million contacts and 30 million companies, and it also runs sequences. Teams that need both usually find people in Apollo and keep accounts in a CRM. Which is cheaper, Apollo or Attio? Both have a US$0 plan. The first paid tiers are Attio Plus at US$35 a user a month billed annually (US$44 monthly) and Apollo Basic at US$49 a seat a month billed annually (US$65 monthly). The middle tiers cost the same: Apollo Professional and Attio Pro are both US$79 billed annually or US$99 monthly. Apollo Organization is US$119 a seat a month, annual only, minimum 3 seats; Attio Enterprise is priced on request. Prices verified 25 Oct 2026. Does the Apollo API work on the free plan? Partly. Apollo's plan card lists API access on Free, but a Free account in October 2026 got HTTP 403 API\_INACCESSIBLE on the people search API, even with a master key; company enrichment worked at 1 credit. Apollo's paid plans include the full API. Attio's API works on its Free plan. Do Apollo and Attio have MCP servers? Yes, both are official and hosted. Apollo's is at `https://mcp.apollo.io/mcp` and accepts OAuth or a master key for headless clients. Attio's is at `https://mcp.attio.com/mcp`, signs in with OAuth only and asks for confirmation before writes. How fast can I load records into each by API? Apollo's bulk create takes up to 100 contacts or accounts per call. Attio has no batch endpoint and allows 25 writes a second per workspace, so a 10,000-record load takes at least about 7 minutes. ## Related [![](/_astro/apollo.DNg6-7d3.svg)Apollo API review](/tool-directory/sourcing/apollo-io)[![](/_astro/attio.CoO4UDxn_ZRTvHO.webp)Attio API review](/tool-directory/crm/attio)[![](/_astro/apollo.DNg6-7d3.svg)![](/_astro/people-data-labs.mXDEg2jz_Z86udK.webp)Apollo vs People Data Labs](/tool-directory/compare/apollo-vs-people-data-labs) Read from [apollo.io/pricing](https://www.apollo.io/pricing), [attio.com/pricing](https://attio.com/pricing) and each tool's API docs.
