Leadspace

Leadspace is a B2B GTM Data Intelligence Cloud and customer data platform that unifies buyer data, account data, and buying signals into the Leadspace Universal Graph. Its API-first enrichment service resolves partial person and company records into full profiles carrying firmographics (SIC, NAICS, industry, revenue, employee counts), corporate family-tree hierarchy, department sizes, funding and investor history, installed-base and website technology signals, weekly buyer-intent models sourced from Leadspace Intent and Bombora, and persona and predictive fit scores. Leadspace exposes single and bulk enrichment, contact discovery (account expansion), and an intent-only refresh API over a single gateway, alongside Leadspace Studio for segment building and SmartForms for real-time inbound web-form enrichment. As of 2026 Leadspace also ships two self-serve agent-facing products that share one account: Leadspace Sidekick, a Chrome extension overlaying verified contact data and fit scoring on LinkedIn, and Leadspace MCP, a hosted remote Model Context Protocol server that plugs the same data graph into Claude, ChatGPT and any MCP-compatible client with per-user OAuth. It integrates with Salesforce, Marketo, Eloqua, and HubSpot. Leadspace is ISO 27001 certified and SOC 2 Type II audited.

Leadspace publishes 6 API contracts indexed on the APIs.io network, including Authorization API, Discovery API, Enrichment API, and 3 more. Tagged areas include MCP, AI Agents, B2B Data, Customer Data Platform, and Data Enrichment.

The Leadspace catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Leadspace’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, changelog, and 37 more developer resources.

What people ask Leadspace 5

The questions people put to an LLM, and the jobs they hand an agent, that Leadspace's APIs answer — each one linked to the operation that does it. Generated by API Evangelist

Leadspace Results API Get the contacts found by a discovery job “Where do I pick up the contacts discovered by my account expansion job?” Get the output of a bulk enrichment job “How do I retrieve enriched records after submitting a bulk enrichment?” Get the results of an intent scoring job “Where do I see the surging intent topics once my intent refresh finishes?”

Leadspace Enrichment API Enrich one person or company record instantly “How do I enrich a single lead or account and get the data back right away?” Submit a batch of records for enrichment “How do I enrich hundreds of leads at once in Leadspace?”

Leadspace Authorization API Get an access token with program credentials “How do I get a bearer token to call the Leadspace v4 APIs?” Refresh an expired access token “Can I renew my bearer token with a refresh token instead of sending my secret again?”

Leadspace Intent API Refresh buyer-intent scores for companies “How can I find out which topics my target accounts are surging on?”

Leadspace Discovery API Find new contacts inside target accounts “How can I find net-new contacts at a list of target companies?”

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. This rating is computed from github.com/api-evangelist/leadspace: open an issue to ask a question, or submit a pull request to add artifacts.
