It is reached at a separate host and uses the same Bearer-token / query-parameter API-key authentication; per the docs "everything is the same except when it's described in the docs of the specific endpoint." Testnet access is included in the Starter, Growth and Scale tiers. As a read-only Hyperliquid data API there are no payment test cards, magic tokens, time simulation, or trigger fixtures — the sandbox is simply the Hyperliquid testnet data surface. docs: - https://docs.hydromancer.xyz/readme/rest-api - https://docs.hydromancer.xyz/readme/get-api-keys environments: - name: mainnet rest_base_url: https://api.hydromancer.xyz websocket_base_url: wss://api.hydromancer.xyz/ws - name: testnet rest_base_url: https://api-testnet.hydromancer.xyz websocket_base_url: wss://api-testnet.hydromancer.xyz/ws notes: >- WebSocket testnet host is inferred from the mainnet pattern; the docs state the REST testnet base explicitly and that testnet behaviour matches mainnet unless an endpoint's own docs say otherwise. gaps: - No payment/card test values (read-only data API, not a payments provider). - No time-simulation / test-clock tooling. - WebSocket testnet URL not stated verbatim in docs (inferred from REST testnet host pattern).
