National Association of REALTORS

The National Association of REALTORS (NAR) is the largest trade association in the United States, representing roughly one million members across residential and commercial real estate. NAR is the industry body that sits above the roughly 500 local Multiple Listing Services, and it is the reason the US residential market has a machine-readable contract at all: MLS Policy Statement 7.90 requires MLS organizations owned and operated by associations of REALTORS to implement the RESO Data Dictionary and the RESO Web API and to stay current within one year of each ratification, with compliance demonstrated through the RESO Certification Process. NAR mandates that standard rather than operating it - RESO is a separate organization, and the listing data behind every certified endpoint is licensed through MLS membership, an IDX or VOW agreement, a broker relationship, or a reseller. NAR itself holds no RESO certification and publishes no self-serve developer portal. Its own API surface is REALTORS M1, the members-first engagement system that replaces NRDS: the M1 Gateway External API is a live, HTTP-Basic-authenticated REST API over member, office, association and data-extract records, whose Swagger 2.0 definition and Postman collection NAR publishes openly on GitHub for external association management system vendors and NAR partners, but whose credentials NAR issues only under a partner relationship.

National Association of REALTORS publishes 24 API contracts indexed on the APIs.io network, including Association API, Data Extract Request API, Data Extract Schedule API, and 21 more. Tagged areas include Real Estate, United States, Industry Body, MLS, and RESO.

The National Association of REALTORS catalog on APIs.io includes 1 Spectral governance ruleset.

National Association of REALTORS’s developer surface includes authentication, engineering blog, documentation, support, and 23 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
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
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
