OpenCode Direct API

Talk to opencode's own servers directly with your opencode API key (from opencode.ai/auth). No local installation and no third-party service in the loop.

Base URL

https://opencode-api.boqsc.eu/go/v1

Send your opencode API key as Authorization: Bearer <key>. Go plan is the default.

Zen vs Go plan

opencode has two billing plans. This subdomain proxies both — switch with the path prefix:

• /go/v1/* → Go plan subscription (https://opencode.ai/zen/go/v1, $5 first month then $10/month, usage limits per 5h/week/month). Default.
• /v1/* → Zen (pay-as-you-go balance, https://opencode.ai/zen/v1). Returns CreditsError / Insufficient balance when the Zen balance is empty.

Model IDs differ per plan: Go uses opencode-go/deepseek-v4-flash in config (the API accepts the bare model id), Zen uses deepseek-v4-flash.
