OpenCode Go

Endpoint and credential

Usage Dashboard queries GET /zen/go/v1/usage with an OpenCode Go API key. The default base URL is https://opencode.ai.

Metrics

The adapter supports independent 5-hour, weekly, and monthly windows, including used/remaining percentages, USD-denominated allowance usage and remaining amounts, limits, and reset timestamps when returned. It also surfaces plan type, exhaustion, balance-fallback state, and per-model usage/request limits.

When the provider omits known per-model limits, the adapter can enrich supported model identifiers with its built-in documented limits. Unknown models remain unknown.

Billing

OpenCode Go is a subscription service. Configure its actual plan commitment under Settings → Connected providers → Billing. Window amounts are allowance state and are not treated as historical PAYG billed spend.

Quota windows overlap and are displayed independently. See Understanding quotas.
