Co-Legal B.V. is a Dutch company (KvK 42135345, Delft) building AI-native legal software and dossier support for Belgian and cross-border Belgium–Netherlands matters — wealth planning and succession, company law and transactions, tax and finance, real estate — sold to law firms, notaries, accountants and tax advisers by proposal, with the private platform behind Cloudflare Access and Microsoft Entra. Alongside it Co-Legal runs a public, free, anonymous, read-only agent at agent.co-legal.be for informational Belgian and Dutch legal and fiscal source questions: an A2A 1.0 agent card signed with JWS ES256 (verifiable against a published JWKS) declaring 17 skills — KBO/BCE company lookup, EU VIES VAT validation, Belgian and Dutch ECLI case-law resolvers, EUR-Lex/CELEX and Justel/wetten.overheid.nl statute resolvers, Flemish inheritance-tax brackets, ECB reference rates, IBAN validation, public legal-corpus search and read, a citation verifier, DOCX concept drafting and a natural-language answer skill — and a remote MCP server at https://agent.co-legal.be/mcp that answers an anonymous tools/list with 12 of those as read-only, idempotent tools. Everything runs on Google Cloud in the EU with the model (claude-opus-5 via Vertex AI) disclosed inside the card. No OpenAPI is published; the MCP tools/list and the card's tool-schema extension are the machine-readable contract.
Co-Legal is listed with 2 APIs on the APIs.io network. Tagged areas include Legal, Legal Research, Tax, Case Law, and Legislation.
Co-Legal’s developer surface includes documentation, API reference, getting-started guide, FAQ, support, engineering blog, pricing, and 33 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 could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% 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):
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)
Request/Response Examples+7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
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)
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.
