If the real job is finding prospects or their emails, use a data provider first, then load the results into whichever CRM you choose. ## Want us to build it for you?

[ Book a call ](/book)[ See case studies ](/case-studies) 05 ## Questions people ask Does Attio have a free plan with API access? Yes. Attio Free costs $0 for up to 3 seats and 50,000 records, and includes the REST API, webhooks and the MCP server. Only the SQL endpoint is held back for Enterprise. Which Salesforce plans include API access? Core ($195), Advanced ($395) and Max ($550) per user a month, billed annually, include the Web Services API. Pro Suite ($100) needs a $25 per user a month add-on. Free Suite and Starter Suite do not include it. A free Developer Edition org has the API with 15,000 calls a day. How do I avoid duplicate records when writing through the API? In Attio, use the upsert endpoint with matching\_attribute set to domains for companies or email\_addresses for people; a repeat updates the same record. In Salesforce, upsert by an external ID field; if more than one record matches, the call returns HTTP 300 with the matches. Do Attio and Salesforce have MCP servers? Both do. Attio's is at `https://mcp.attio.com/mcp` on every plan and signs in with OAuth. Salesforce's hosted MCP servers are generally available for Enterprise Edition orgs and above and are off until an admin enables them. Can Attio handle bulk imports through the API? Attio has no batch record endpoint, so records are written one per call at up to 25 writes a second. Salesforce offers sObject Collections for 200 records per call and Bulk API 2.0 for up to 150 million records a day. ## Related [![](/_astro/attio.CoO4UDxn_ZRTvHO.webp)Attio API review](/tool-directory/crm/attio)[![](/_astro/salesforce.C2obBAuF.svg)Salesforce API review](/tool-directory/crm/salesforce)[![](/_astro/apollo.DNg6-7d3.svg)![](/_astro/attio.CoO4UDxn_ZRTvHO.webp)Apollo vs Attio](/tool-directory/compare/apollo-vs-attio)[![](/_astro/attio.CoO4UDxn_ZRTvHO.webp)![](/_astro/clay.CHDKXtEw_Z1QRVH4.webp)Attio vs Clay](/tool-directory/compare/attio-vs-clay)[![](/_astro/attio.CoO4UDxn_ZRTvHO.webp)![](/_astro/hubspot.ClO2484y_SluoY.webp)Attio vs HubSpot](/tool-directory/compare/attio-vs-hubspot)[![](/_astro/hubspot.ClO2484y_SluoY.webp)![](/_astro/salesforce.C2obBAuF.svg)HubSpot vs Salesforce](/tool-directory/compare/hubspot-vs-salesforce) Read from [attio.com/pricing](https://attio.com/pricing), [salesforce.com/sales/pricing](https://www.salesforce.com/sales/pricing/) and each tool's API docs.
