SSE drop streams vs full-book WebSocket
Answer: an SSE drop alert tells you a threshold move happened; a full-book WebSocket streams every matching market upsert. PinnFeed Builder is the full-book WS; steam shortcuts also use GET /v1/drops. We do not claim latency vs named SSE vendors.
Pick#
| Need | Use |
|---|---|
| Whole board + model inputs | WebSocket snapshot/delta |
| Only “something shortened” | /v1/drops or your own steam rule on the WS |
