    Introduction

    Zuse is a maintained, board-verified index of licensed professionals, available over a REST API and an MCP server.

    Licensure data is public, but it is scattered across dozens of state and provincial boards, each with its own format, search page, and refresh cycle. Zuse ingests those rosters, normalizes them into one schema, resolves the same person across jurisdictions, and serves the result as a small set of resources.

    The same capabilities are exposed as tools on the MCP server.

    Names

    The console and the website use plain names. The API uses identifiers that do not change. They are the same things:

    One set of rules

    Every endpoint follows the same conventions, so learning one teaches the rest:

    • Resources are plural nouns. GET reads, POST creates. There are no verbs in paths.
    • Lists page the same way. limit and cursor in, pagination.next_cursor out. See Pagination.
    • Filters and sorting are query parameters, with the same names everywhere: postal_code, radius_miles, profession, specialty_type, sort.
    • Responses share one envelope: data, then pagination and meta for lists, then billing.
    • Every record has an id, and a reference to another resource is always <resource>_id.
    • Dates are ISO 8601 (2027-01-31). Distances are miles and say so in the field name.
    • Errors share one shape with a stable code. See Errors.
    • Retries are safe. Send an Idempotency-Key and a repeated request is not charged twice. See Idempotency.

    Two layers, kept apart

    Zuse returns two different kinds of information and never blends them:

    • The verified record: identity and licensure taken from the licensing board of record. Professionals, practices, licenses and people read only from this layer.
    • The derived layer: employer, education, public contact details and social profiles gathered from the public web. Enrichments return this layer, marked "layer": "derived", with a source URL for each field.

    If a field came from a board, it is authoritative. If it came from the web, it is a cited best effort and is labeled that way.

    GET /v2/jurisdictions returns what is covered right now. A license search for a jurisdiction that is not indexed answers meta.outcome: "jurisdiction_not_indexed" rather than an empty result, so a missing board is never mistaken for a missing license.
