API documentation

Authentication

OpenAI-compatible clients use a Bearer token. Anthropic clients use X-API-Key. Do not send two different keys in the same request.

Authorization: Bearer jsk_live_your_key

X-API-Key: jsk_live_your_key

Endpoints

Request scope

Generation requests use JSON and must include a currently listed model. The first release supports plain-text system, user, and assistant messages plus common sampling controls.

• Maximum request body: 4 MiB.
• Current output limit: 512 tokens.
• Tools, multimodal content, structured output, stateful Responses, and Anthropic thinking are not yet supported. Unsupported input fails explicitly rather than silently degrading.

Streaming

Set stream: true to receive text/event-stream. Each endpoint emits its native SSE event structure; clients should consume the terminal event rather than treating a closed connection as successful completion.

Usage and billing

Accounts use prepaid CNY credit. The active model price is snapped when a request is admitted, then final cost is settled from the actual input and output token counts reported by compute. Usage statistics can take a few seconds to update.
