Prospeo
Prospeo · Ranked #10 of 19 in Data Enrichment APIs
Email, phone and company data API with 30+ search filters, plan-tiered published rate limits, a free plan that explicitly includes API access and an OAuth MCP server, but credits expire monthly and no official SDK was found.
Verified email and mobile finding for outbound
Overview
Prospeo is a B2B contact-data provider offering person and company enrichment (single and bulk), person and company search (about 200M+ contacts and 30M+ companies with 30+ filters), search suggestions and an account endpoint, plus an MCP server at mcp.prospeo.io with OAuth 2.0 or API-key auth. The docs open with free API access for all users and carry a copy-for-AI-agent affordance; integrations exist through Composio, Cargo and similar tools.
Documentation covers endpoints, filters, rate limits by plan and MCP set-up. Published limits: enrich endpoints Starter/Growth 5/sec, 300/min and 2,000-5,000/day, Pro 30/sec, 1,800/min and 500,000/day; search Starter 1/sec and 1,000/day, Growth 2/sec and 4,000/day, Pro 5/sec and 250,000/day. Credits: a person-search page of 25 results costs 1 credit, an email 0.5-1, a verification 0.1, a mobile 10; account lookups are free. Pricing is public and per user (Free 100 credits per the help centre, though a third-party source says 75; Starter about $49/month for 2,000 credits; Growth about $99/month for 5,000; Pro about $249/month for 15,000), and unused credits expire each cycle, the most common complaint.
Gaps: no official SDK found, no confirmed official status page or SLA (StatusGator shows 32 user problem reports in 30 days and one degraded-performance incident on May 7, 2026), and per-user pricing multiplies for teams. Reputation is good: Trustpilot 4.7/5 (139 reviews) and G2 about 4.6/5 (608 reviews as of August 2026), with praise for deliverable emails and connecting mobiles.
How this score is derived
The APIbenchmarks Index is a weighted sum of four dimensions, each scored on an absolute 0–100 reference scale. See the methodology for every mapping.
| Dimension | Score | Weight | Contribution |
|---|---|---|---|
| Documentation & DXapi-docs covers person and company enrich/search endpoints, filters, search suggestions, rate limits by plan, errors and MCP docs with a copy-for-agents option; no SDK docs and parts of auth/error detail could only be confirmed at the overview level. | 78 | 30% | 23.4 |
| ReliabilityThin evidence: no verified status page or SLA, StatusGator logged 32 user problem reports over 30 days and IsDown lists a degraded-performance incident on May 7, 2026; limits are documented and reviews are favourable, so scored conservatively. | 66 | 25% | 16.5 |
| Ecosystem & SDKsAn MCP server with OAuth and API-key auth, Composio and other workflow integrations, a browser extension and CRM integrations on Growth, but no official SDKs were found. | 62 | 25% | 15.5 |
| AccessibilityThe docs state free API access for all users, the Free plan has 100 monthly credits (help centre; a third party says 75), pricing is public and self-serve, but credits expire each cycle and plans are priced per user. | 82 | 20% | 16.4 |
