LegendTrade Wallets API

openapi: 3.1.0
info:
  title: Legend Info Health Wallets API
  version: 0.1.0
  summary: Hyperliquid-compatible info API with local processing, operated by Legend (legend.trade).
  description: 'The public read surface of Legend''s trading platform, served at https://api.legend.trade. The service self-identifies as `@legend/hl-node` v0.1.0 — "Hyperliquid-compatible info API with local processing" — and mirrors the Hyperliquid `POST /info` request-type convention while adding Legend-specific endpoints (`/sparklines`) and an operator-authenticated wallet registration surface used for fill tracking.

    This description was GENERATED by the API Evangelist enrichment pipeline from the API''s own self-describing root document (GET https://api.legend.trade) and from live probes of each endpoint on 2026-07-19. Legend publishes an `openapi.json` at docs.legend.trade/api-reference/openapi.json, but as of this run that file is the unmodified Mintlify "OpenAPI Plant Store" scaffold and does not describe the Legend API — it was deliberately NOT harvested. Request/response schemas below are typed only where a live response was observed; unobserved shapes are left open rather than invented.'

      description: The `/wallets/*` endpoints are authenticated — unauthenticated requests return `401 {"error":"Unauthorized"}`. Legend does not publish the credential format for this operator surface; `bearer` is recorded as the observed-unauthenticated default and is NOT a documented provider claim.
