Prospeo is primarily a data-enrichment API rather than a full outbound platform. Its documented surface centers on person and company enrichment, search endpoints, account-usage introspection, and a revamped API whose old endpoints were scheduled for migration before March 1, 2026. It also exposes a hosted MCP server and an installable local MCP server package. A Chrome extension is listed as included on every plan in the vendor's own pricing table; the web app's interior was not verified because it requires an account login.

Sales, marketing, and outreach teams that need a dedicated email/phone enrichment and verification data source to feed into their own sequencing, CRM, or no-code tooling, rather than an all-in-one outbound platform.

Prospeo's own pricing comparison table records "No access" against both the Enrich API and Search API rate-limit rows for the Free plan, so a team wanting programmatic or MCP access should expect to be on a paid tier - though the API introduction page simultaneously advertises "Free API access for all users", and the vendor's two pages disagree as of 2026-08-21. Pricing is per user rather than per workspace, so a small team sharing one data source pays for every seat. Teams wanting an all-in-one outbound platform (sequencing, multichannel campaigns, CRM sync built in) should look elsewhere - Prospeo's documented surface is enrichment/search data, not campaign execution.

Providers that resolve a person or company to verified contact data — email, phone, firmographics — through an API or a bulk upload.

ApolloAPIBundles the database with a sequencer, so it is bought as a whole outbound stack as often as for the data.CognismDropcontactExploriumAPIMCPFindymailFullEnrichHunterAPILeadMagicAPISurfeAPI
