Deeplead

Deeplead finds B2B customers and runs cold email outreach to them. It searches local businesses, companies and people, finds decision makers with verified work emails and phone numbers, and sends personalized campaigns from warmed-up inboxes with one inbox for every reply. The same data is available to developers and AI agents through a REST API with an OpenAPI 3.1 contract and a remote MCP server, both authenticated with an API key or OAuth.

Deeplead publishes 7 API contracts indexed on the APIs.io network, including Account API, Businesses API, Contacts API, and 4 more. Tagged areas include Company, Lead Generation, Cold Email, Artificial Intelligence, and Sales Automation.

Deeplead’s developer surface includes support, documentation, API reference, getting-started guide, signup flow, engineering blog, pricing, and 13 more developer resources.

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/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it.
