Limit Free trial / Pro Enterprise Limit 60 calls/min, queue 100 Custom rate limits & priority queue More on limitsLess Up to 100 contacts per bulk call (6,000 contacts/min). Default queue 100 concurrent enrichments and 100 concurrent reverse lookups per workspace; extra contacts wait, jobs never expire. Polling consumes the limit. Higher limits and queue for partners/Enterprise. ## How to get an API key FullEnrich uses API key. The steps below follow FullEnrich's own docs. 1. Create a FullEnrich account. The Free trial plan includes API access. 2. app.fullenrich.com/app/api after free trial signup (no card) AND phone/SMS verification, which is mandatory before the API page opens; keys can carry a consumption limit (per-user credit limits are a Pro feature). 3. Make a first call: Start waterfall enrichment for 1-100 contacts (work email, mobile, personal email). Keep the key in an environment variable, never in the command. ``` curl -X POST "https://app.fullenrich.com/api/v2/contact/enrich/bulk" \ -H "Authorization: Bearer $FULLENRICH_API_KEY" \ -H "Content-Type: application/json" \ -d '{}' ``` ## Where the docs live What Where Documentation [docs.fullenrich.com/api/v2/general/introduction](https://docs.fullenrich.com/api/v2/general/introduction) API reference [docs.fullenrich.com/llms.txt](https://docs.fullenrich.com/llms.txt) OpenAPI spec [docs.fullenrich.com/api/v2/reference/openapi.yaml](https://docs.fullenrich.com/api/v2/reference/openapi.yaml) llms.txt [docs.fullenrich.com/llms.txt](https://docs.fullenrich.com/llms.txt) Changelog [fullenrich.com/changelog](https://fullenrich.com/changelog) Base URL `https://app.fullenrich.com/api/v2` MCP server `https://mcp.fullenrich.com/mcp` ## Strengths and limits ### Where it fits - Maximising find rate for mobiles and work emails without wiring your own provider waterfall - Mobile numbers with line type, active status, US/Canada owner-name match and connect-rate buckets - Embedding enrichment in a product: async batches of 100, per-contact webhooks, signed payloads, custom passthrough fields - Reverse email lookup (work or personal email to full person + company profile) at 1 credit - Unlimited-seat teams: no per-user pricing ### Where it falls short - Real-time synchronous lookups: enrichment takes typically 30-90 seconds per contact - Cheap bulk list building: search costs 0.25 credit per record returned (Prospeo is 1 credit per 25) - Stacking inside another waterfall - High-throughput polling: 60 calls/minute shared across all endpoints ### Worth knowing - Catch-all emails are charged 1 credit like Deliverable ones (credits doc); filter on status if you only want DELIVERABLE (2% bounce) vs HIGH\_PROBABILITY (9% bounce) - No dedup within the same bulk, and simultaneous requests for the same contact are not deduplicated; dedup is on exact input, so a variant name/domain/LinkedIn URL is charged again - Results are kept 3 months only (GDPR); fetching an enrichment\_id after that errors, and re-enriching after 3 months costs credits again - custom field values must be strings; a number returns an error - If no most\_probable\_\* field comes back, nothing passed verification and no credit was used, even when work\_emails\[\] or phones\[\] are non-empty 7 moreShow fewer - Search offset is capped at 10,000; use search\_after beyond that, and its ordering can shift after the monthly database update - Lookup endpoints are billed at search pricing, not free - Test for free with the hard-coded FullEnrich team contacts (exact data on the credits page) - The pricing comparison table says search has '15+ filters' while the Pro plan card says '30+'; the OpenAPI people search lists 30 filter fields - Docs say 20+ providers, pricing says 25+; which providers are chained is not published - Free trial is not frictionless: signup needs no card, but onboarding forces phone (SMS) verification before the 50 credits or the API key unlock. - Plan-differences table: per-user credit limits, credit monitoring and low-credit alerts are NOT on the Free trial, despite 'full Pro feature set'. Source: [fullenrich.com/pricing.md](https://fullenrich.com/pricing.md) (verified 2026-10-25) ### Our take We left FullEnrich out of an enrichment waterfall we built for a B2B data company: it is itself a multi-provider waterfall that overlapped the providers we already called, and the orchestration platform we used could run it only on the platform's own credits. ## Who should use it Use FullEnrich for Maximising find rate for mobiles and work emails without wiring your own provider waterfall Look elsewhere for Real-time synchronous lookups: enrichment takes typically 30-90 seconds per contact ## If FullEnrich is not the answer Other Enrichment tools in this directory, each with its own review.
