FullEnrich

FullEnrich is a B2B contact enrichment platform that finds verified business emails, personal emails and mobile phone numbers by running a waterfall across 25+ data vendors, billing credits only when data is found and passes verification. Its v2 REST API covers four surfaces — asynchronous bulk contact enrichment, bulk reverse email lookup, and synchronous people/company search and lookup across 800M people and 50M companies. Alongside the REST API it operates a first-party remote MCP server with 13 tools, publishes nine MIT-licensed Agent Skills, serves an A2A agent card, and maintains a machine-readable pricing document written for AI agents to read.

FullEnrich publishes 5 API contracts indexed on the APIs.io network, including Account API, Company API, Contact API, and 2 more. Tagged areas include B2B Data, Contact Enrichment, Email Finder, Phone Finder, and Waterfall Enrichment.

The FullEnrich catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

FullEnrich’s developer surface includes authentication, sandbox, documentation, API reference, getting-started guide, support, engineering blog, and 44 more developer resources.

Kin Score

Kin Score Kin Score How this is scored →
scored 2026-11-13 · rubric v0.28.0
Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 7

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
