Your first batch in 10 minutes

Sign up and verify your email. Each new workspace ships with free credits so you can try the platform end-to-end before topping up.

From the dashboard, go to Account → API keys and create a key. Store it as BATCHROUTER_API_KEY in your environment — keys are shown once.

Each line is a single request. The format mirrors the OpenAI Batch input file, so existing JSONL works without conversion.

{"custom_id":"r-1","method":"POST","url":"/v1/chat/completions","body":{"model":"gpt-4o-mini","messages":[{"role":"user","content":"Summarize: ..."}]}}
{"custom_id":"r-2","method":"POST","url":"/v1/chat/completions","body":{"model":"gpt-4o-mini","messages":[{"role":"user","content":"Summarize: ..."}]}}

Upload the file to /v1/batches/quote. You receive a price across eligible provider lanes, locked for 10 minutes.

curl https://api.batchrouter.dev/v1/batches/quote \
  -H "Authorization: Bearer $BATCHROUTER_API_KEY" \
  -F "file=@batch.jsonl"

Accept the quote to submit. Batchrouter routes to the cheapest eligible provider, retries transient failures, and notifies your webhook on completion.

curl https://api.batchrouter.dev/v1/batches \
  -H "Authorization: Bearer $BATCHROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"quote_id":"qt_...","webhook_url":"https://example.com/hooks/batchrouter"}'

Your endpoint receives a signed batch.completed event with a download URL for the output JSONL. Verify the signature, then process the rows.
