Models

Route LLM and multimodal requests through SeaRouter with provider credentials hidden server-side.

Responses API

POST /api/searouter/llm/v1/responses is the OpenAI-compatible route for text and reasoning workflows.

Use the standard SeaChat base URL and an API key with model:invoke or searouter:invoke.

curl https://seachat.ai/api/searouter/llm/v1/responses \
  -H "Authorization: Bearer $SEACHAT_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"gpt-5.5","input":"Summarize the SeaChat API in one paragraph."}'

Multimodal invoke

POST /api/searouter/v1/invoke/{modality}/{model}/{version} supports image, video, audio, embedding, rerank, and other modality-specific providers.

Generated media is imported into managed SeaDB artifacts when the provider returns bytes or URLs. Render the returned outputs[].url directly and keep artifactRefId for later references.

curl https://seachat.ai/api/searouter/v1/invoke/image/bytedance_seedream_4_0/latest \
  -H "Authorization: Bearer $SEACHAT_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt":"A clean product diagram for an agent API gateway"}'

Discovery

Use /api/searouter/v1/help, /api/searouter/v1/help/modalities, and /api/searouter/v1/help/models/search before selecting models or provider-specific fields.
