API
Quick start
Set OPENROUTER_API_KEY locally. Python requires requests; JavaScript runs in Node.js. Keep the key on the server.
This submits an asynchronous batch using the base model ID. A job ID confirms submission, not completion.
curl --fail-with-body https://openrouter.ai/api/beta/batches \
-H "Authorization: Bearer $OPENROUTER_API_KEY" \
-H "Content-Type: application/json" \
-d '{"endpoint":"/v1/chat/completions","model":"anthropic/claude-fable-5.1","requests":[{"custom_id":"request-1","body":{"messages":[{"role":"user","content":"Hello!"}]}}]}'
# Replace JOB_ID with the returned id to check progress.
curl --fail-with-body "https://openrouter.ai/api/beta/batches/JOB_ID" \
