WSDL
WSDL (Web Services Description Language) is a W3C standard XML format for describing web service interfaces. It defines services as collections of network endpoints (ports) that exchange messages, specifying the abstract operations, message formats, and protocol bindings needed to interact with a web service. WSDL 2.0 became a W3C Recommendation on June 26, 2007, and adds support for all HTTP request methods, making it more suitable for RESTful web services than its predecessor WSDL 1.1.
API Evangelist profiles WSDL the way a machine reads it — 41 machine-readable artifacts, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
How we profile WSDL
Each block below is one kind of artifact we hold for WSDL. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Features 10
The notable capabilities this provider advertises, captured as structured features so they can be searched and compared instead of read one landing page at a time.
Notable capabilities this provider offers.
Abstract Service Interface
Defines abstract interfaces separating service contract from protocol binding.
Message Exchange Patterns
Supports In-Only, Robust In-Only, and In-Out message exchange patterns.
SOAP Binding
Native SOAP 1.2 binding for web service interoperability.
HTTP Binding
HTTP binding supporting all HTTP methods including GET, POST, PUT, DELETE.
RPC Style Operations
RPC-style operation dispatch with input and output message wrappers.
Type System Integration
Integrates with XML Schema for defining message types.
Multiple Endpoints
Supports multiple endpoints per service with different protocol bindings.
Namespace and Modularity
Uses XML namespaces to enable modular and reusable service descriptions.
Operation Safety Declaration
Allows marking safe read-only operations per web architecture principles.
RDF Mapping
Normative mapping to RDF for linked data and semantic web integration.

Semantic Vocabularies 1
JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

JSON-LDSpectral Rules 1
Governance rulesets we run against this provider's specs — the automated checks behind parts of the score. Profiling them makes the quality bar explicit and re-runnable, not a matter of opinion.

SPECTRALJSON Schema 8
Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

This is an independent, third-party profile of WSDL, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
