Adapt (adapt.io) is a B2B lead intelligence and sales acceleration platform that provides a database of 250M+ verified business contacts, 16M+ decision makers, and 12M+ company profiles, refreshed at roughly 5M records per day. Adapt sells the data three ways — through a web Prospector for list building and ABM, a LinkedIn/website Chrome extension for in-context contact discovery, and a public REST API for programmatic search, enrichment, and contact purchase. The Prospect API exposes four operations (contact search, company search, contact enrichment, and contact purchase / fetch) with 50+ firmographic, technographic, and demographic attributes per record, header- based authentication via account email + API key, and a 250 requests-per- minute rate limit. Pricing is published for self-serve Free, Starter ($49/mo) and Basic ($99/mo) tiers; API access is gated to the custom enterprise plan with negotiated email, phone, and enrichment credit allotments. Adapt is primarily used by sales, marketing, and RevOps teams for outbound campaigns, CRM enrichment, lead scoring, ICP list building, and data hygiene, with CRM exports to Salesforce, HubSpot, Pipedrive, Zoho, Outreach, and Salesgear.
Adapt publishes 9 API contracts indexed on the APIs.io network, including Account API, Company API, Contact API, and 6 more. Tagged areas include B2B Data, Contact Data, Company Data, Lead Intelligence, and Sales Intelligence.
The Adapt catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
Adapt’s developer surface includes authentication, developer portal, documentation, getting-started guide, signup flow, pricing, engineering blog, and 38 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/.

Agent readiness — checks not met, largest first (exact, from this profile):
MCP Server+12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Idempotency+9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card+8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Delegated User Identity+6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
Typed Event Surface+6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
7 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
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.
Overlays applied on top of this provider's contracts. Each card says who wrote it: a document the provider publishes, or one API Evangelist derived or generated.
