FullEnrich API + MCP vs Prospeo API + MCP

FullEnrich API + MCP

Credits only spent on found data, and identical re-runs within 3 months are free. Enrichment sources are third-party providers the vendor doesn't name.

Prospeo API + MCP

MCP tool descriptions say when to use each tool, its credit cost and the next call. No status page, SLA or changelog.

FullEnrich API + MCP

1. Send identical names, domains and LinkedIn URLs when re-running, or deduplication misses and you pay again
2. Expect 30 to 90 seconds a contact. Use the webhook or poll get_enrichment_results
3. Ask for mobiles only when needed. They cost 10 credits against 1 for a work email
4. Call list_industries and list_seniorities before filtering search
5. Use the 0-credit test contacts in the docs to check an integration

Prospeo API + MCP

1. Call search_suggestions before using location, technology or industry filters, or the search returns nothing
2. Pass person_id values from search into bulk_enrich_person, 25 at a time
3. Branch on the body error_code, not the HTTP status, which is 400 for most failures
4. Set enrich_mobile only when needed. A mobile costs 10 credits against 1 for an email
5. Use Enrich Person. The old Email Finder endpoint was removed in March 2026
