Espresso Network Query Service API
The public REST and WebSocket API served by Espresso query services and nodes (Tide Disco framework). Comprises independent modules — availability (Tiramisu DA blocks/headers/payloads/VID), node, status, catchup, state, explorer, hotshot-events streaming, and submit (post transactions to the public mempool) — each versioned via URL path (v0/v1) and negotiating JSON or binary via Content-Type/Accept. Read endpoints are unauthenticated; there is no "latest block" query — clients index by block height or hash.
