Configuration
| Variable | Required | Secret | Description |
|---|---|---|---|
| THREE_WS_BASE | — | — | Base URL of the three.ws API that serves the signal-marketplace endpoints. Override only when self-hosting or targeting a preview deployment. |
| THREE_WS_TIMEOUT_MS | — | — | Per-request timeout in milliseconds for the live marketplace reads and subscription writes. |
| THREE_WS_API_KEY | — | yes | three.ws API key (sk_live_… / sk_test_…) for the account-scoped follower tools (get_subscriptions, subscribe_signal, set_subscription_status). Optional — the public discovery and leaderboard tools work without it. subscribe_signal in live mode spends real USDC, so treat this key like cash. |
