extends: openapi/legendtrade-info-openapi.yml
x-api-evangelist:

  method: generated
  source: >-
    API Evangelist enrichment pipeline. Records the provenance and caveats that
    apply to the generated Legend spec, so consumers can tell provider-published
    facts from pipeline-derived ones. Note that the base spec is itself
    generated from Legend's self-describing API root — Legend publishes no
    OpenAPI of its own.

  update:
    x-apievangelist-enriched: '2026-07-19'
    x-apievangelist-spec-provenance: >-
      Generated from the API's self-describing root document (GET
      https://api.legend.trade) and verified with live probes of every
      endpoint. Legend's linked openapi.json is an unmodified Mintlify sample
      scaffold and was not used.

      name: Hyperliquid
      url: https://hyperliquid.xyz
      relationship: >-
        Legend is a builder on Hyperliquid. Orders execute on Hyperliquid's
        order book and this API deliberately mirrors Hyperliquid's info and
        WebSocket conventions, so Hyperliquid's docs are the authority for
        per-request-type payload shapes.
- target: $.paths['/info'].post
  update:
    x-apievangelist-note: >-
      Multiplexed endpoint — the response schema varies by request type and is
      not modelled per type, because Legend publishes no payload reference.
      Only the `meta` response was observed live.

      Authenticated operator surface. Credential format is not published by
      Legend; the securityScheme in the base spec records observed 401
      behaviour, not a provider claim.
