Market overview

client.MarketOverview returns one row per spot market (last price, 24h stats, and related fields). Public, no authentication required.

Methods

Method Summary
List Overview rows (optional symbol filter).
CreateSubscription Snapshot-then-stream merged rows (preferred).
Subscribe Raw Centrifugo batches (Messages()).

List(ctx, symbols, limit, pageToken, includeSparklines)

overview, err := client.MarketOverview.List(ctx, []string{"BTC-USDT"}, 50, "", false)
if err != nil { log.Fatal(err) }
for _, m := range overview.Markets {
    fmt.Println(m.SymbolID, m.Symbol, m.LastPrice)
}

The pageToken argument is accepted for signature parity; filtering is primarily via symbols and limit.

CreateSubscription(ctx, opts)

Managed books expose Updates() (slice of merged rows), not Messages().

import "github.com/Fabric-Labs/polyester-sdk-go/services"

sub, err := client.MarketOverview.CreateSubscription(ctx, services.MarketOverviewCreateSubscriptionOptions{
    Symbols: []string{"BTC-USDT"},
    Limit:   50,
    OnEvent: func(rows []models.MarketOverviewEntry) {
        for _, m := range rows {
            fmt.Println(m.Symbol, m.LastPrice)
        }
    },
})
if err != nil { log.Fatal(err) }
defer sub.Close()

for rows := range sub.Updates() {
    fmt.Println(len(rows))
    break
}

Subscribe(ctx)

Raw batches, consume with Messages(). Prefer CreateSubscription for dashboards.
