Functions5

provider::claude-code::abort

Function

Cancel the in-flight upstream stream for a request_id (router::abort fan-out), stopping billed generation immediately.

Request
  • request_idstringrequired
Response
  • abortedbooleanrequired

provider::claude-code::count_tokens

Function

Count prompt tokens for {model, system_prompt?, tools?, messages} via the upstream count_tokens metering endpoint with the Claude Code subscription OAuth token; never runs the model and costs nothing.

Request
  • messagesany of[]required

    Wire agent messages, the same shape `provider::claude-code::stream` accepts. Must be non-empty.
