The REST surface is a single POST /info dispatcher whose `type` field selects the operation, mirroring the native Hyperliquid pattern. Protocol evolution is communicated through a dated WebSocket changelog; changes are described as additive with "no wire-format change: no field was added, removed, or renamed." deprecation: policy_documented: false headers: none-documented upcoming: - change: l4BookUpdates `merge` will become the default for coin-list subscriptions in a future release date_announced: '2026-08-20' guidance: >- Set `merge` explicitly now — `true` to adopt early, `false` to pin today's one-stream-per-subscribe behaviour through the change. The flag stays accepted afterwards. notes: >- No RFC 8594 Sunset/Deprecation header policy is documented. The only announced behavioural change is the l4BookUpdates merge-default migration above; changelog entries are otherwise additive. sla: published: false notes: No formal SLA/uptime commitment is published; "no more rate limits" and low-latency infra are marketing claims. status_page: null incidents_page: https://docs.hydromancer.xyz/readme/incidents incidents_notes: >- A public incident-report page is maintained (not a live status dashboard). One incident is on record: 2026-08-22, degraded hosting-provider network performance, API and WebSocket unavailable ~1 hour, resolved.
