Formless Host

Binance market panel

Binance Market Canvas and Binance Market Pro panels in Click
The Canvas and native daScript presentations consume the same typed Binance capability supplied by an isolated Host plugin.

dev.formless.binance-market is the reference for a rich Click frontend backed by an isolated external-data plugin.

The Host plugin uses public Binance REST for symbol search, klines, funding, and turnover, plus a long-lived WSS subscription for live bid/ask. Both paths use exact allowlisted external destinations through the generation-private egress bridge; Host does not terminate TLS or inspect payloads.

Two panels demonstrate the same capability:

  • Binance Market Canvas: responsive HTML/CSS, shared Click theme tokens, market list, metrics, chart, and live book.
  • Binance Market Pro: native daScript controls and plotting through the typed Host capability.

The WSS subscription is intentionally endless while demanded. It ends on explicit cancellation, panel/provider teardown, policy withdrawal, upstream terminal close, or generation disposal—not because of a short request timeout.

Use this architecture for services where discovery is request/response but live state is subscription-based. Keep external credentials and sockets in the Host plugin; send typed market results to panels.
