BizVerify

BizVerify is a business entity verification (KYB) API built for AI agents as much as for developers. It confirms business registrations, status, good standing and available public company details across supported US and international jurisdictions, through a REST API and a hosted MCP server that exposes the same capability as nine tools. The agent surface is the unusual part for a provider this size: alongside the OpenAPI it publishes an llms.txt, a proper RFC 9727 API catalog served as application/linkset+json, per-vendor tool manifests at /tools/openai.json and /tools/anthropic.json, and an open-source MCP client repository. Access is credit-based with a free-tier allowance, and the MCP server answers tools/list without credentials.

BizVerify publishes 10 API contracts indexed on the APIs.io network, including Account API, Auth API, Billing API, and 7 more. Tagged areas include Business Verification, KYB, Entity Verification, Compliance, and MCP.

The BizVerify catalog on APIs.io includes 1 Spectral governance ruleset.

BizVerify’s developer surface includes documentation and 15 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/.

      so it is not callable as published. The baseURL recorded here comes from the API catalog linkset and from the live host,
      not from the spec.'
    no_schemas: 21 operations and zero `components.schemas`. Request and response bodies are undescribed, which is the single
      largest gap in the contract and the highest-leverage thing to fix.
    user_agent_gate: https://api.bizverify.co/v1/openapi.json returns HTTP 403 to `Python-urllib/3.14` while returning 200
      to curl, to an empty user-agent, and to `python-requests/2.32.3`. So the block is specific to urllib rather than to
      automated clients generally — narrower than it first appeared, but still enough to silently starve any harvester built
      on urllib, which would record nothing and understate the provider. Harvested here with curl.
  note: Built from the provider's own published artifacts, all fetched and measured. The MCP property is emitted because the
    server is hosted and answers tools/list unauthenticated — unlike a local-stdio install, which is described in prose only.
    Pricing is credit-based with a free tier per the MCP get_config tool, but no machine-readable rate card was found, so
    plans and rate limits are not asserted.
