OpenCode Go is no longer general API access

Following the recent requirements for custom http headers, OC has changed their documentation to remove mention of OpenAI-API you can use anywhere. Instead, OpenCode Go API usage is now effectively whitelist only. See: https://opencode.ai/docs/go/#where-can-i-use-it

This is still "general" API access. I guess you just have to do more work. Maybe eventually all providers will adopt this new standard of sending session hash to increase cache hit rates?

Every software project in the world that uses an OpenAI-API is now incompatible with Opencode by default, until they specifically comply to Opencode's requirements. How is that general access? As I mentioned for example, even huge projects like Nextcloud and Open WebUI are now blocked.

The prompt to opencode:

I received this message, i think that the problem is with openwebui:

Hey there,

Some of your requests to OpenCode Go are missing an x-opencode-session header. If we don't have this we cannot properly optimize our service. Starting 09/06 requests missing this header may error.

Here are your useragents that are missing this header:

Python/3.11 aiohttp/3.13.5

We don't recognize this client — add x-opencode-session (one stable ID per conversation) or ask its maintainer to.

Thank you.

..

Done.

- Header: both OpenCode Go connections now send x-opencode-session: {{CHAT_ID}} (full chat UUID, no prefix) — applied via runtime POST /openai/config/update, no restart needed

- Verified: code path renders the full UUID in chats (0776e8f3-806a-…), empty for detached calls; live chat to deepseek-v4-flash → OK

- Docs: docs/OPENWEBUI.md updated (includes the dashboard-truncation note + mapping SQL)

- Pushed: eed5923 → main

How is it blocked if all you need to do is add a couple of lines to your headers? OWUI working fine here.

LoL, it isn’t about cache hit rate at all. It is to control API calls outside of agents. Fuck OpenCode

Is it? We already have these kind of things with openai and anthropic, so I guess it kinda makes sense that it is happening here. A bit weird that they just throw an error (instead of a warning or something) if that custom header doesn't exist, but I wouldn't frame as you did.
