  live probes of premierlacrosseleague.com/api/graphql, shop.premierlacrosseleague.com and its
  /.well-known/ discovery documents on 2026-08-02

  Derived from probes, not from an OpenAPI document — the Premier Lacrosse League publishes no
  OpenAPI, no developer portal and no authentication documentation. Nothing here is inferred; each
  scheme records an observed response.

  description: >-
    The Apollo Server GraphQL API that backs the league's web and stats properties requires no
    credential, but enforces a CORS-style origin allow-list at the application layer. A POST
    without an allowed Origin header returns HTTP 403 with body {"error":"Origin not allowed"}.
    With Origin set to https://premierlacrosseleague.com the request is accepted and validated.
    There is no published way for a third party to obtain authorized access.
  observed:
    no_origin: {http_status: 403, body: '{"error":"Origin not allowed"}'}
    allowed_origin: {http_status: 400, note: 'request accepted, failed GraphQL validation only'}

    Product and collection JSON on the store is served unauthenticated
    (GET /products/{handle}.json, GET /collections/{handle}/products.json,
    GET /search?q={query}&type=product). Documented by the store's own llms.txt.

  description: >-
    The store's MCP endpoint does not gate on a bearer token for tools/list; it gates on a UCP
    agent profile URI. An anonymous tools/list returns HTTP 422 with JSON-RPC error -32001
    invalid_profile_url ("Unable to fetch agent profile: Missing profile uri"). Payment completion
    additionally requires contemporaneous human buyer approval.
  bearer_methods_supported: [header]
gaps:
- No API key programme, no developer registration, no partner/media data-access documentation.
- No security.txt on any host, so no published security contact.
