Given a docs or API URL, detect the OpenAPI/Swagger document behind it and summarize the API structure.

List endpoints from a discovered OpenAPI document with optional filtering by tag, method, or path fragment.

Search cached endpoints for a previously detected OpenAPI spec using a server-side semantic-style scorer over endpoint metadata and schema field names.

Suggest a likely API call sequence for reaching a target endpoint or accomplishing a goal, such as creating prerequisites before creating a dependent resource.

Return request/response details for a specific endpoint in the discovered OpenAPI document.

Call an endpoint discovered from the OpenAPI document, optionally applying auth automatically and sending query, path, headers, and payload data.

Trace where a parameter or field such as userId is used across path parameters, query parameters, request bodies, and response bodies.

Find endpoints that are structurally related to a source endpoint based on shared resource paths, identifiers, tags, and parent/child URL patterns.
