14 keys, zero downtime.

Hit a rate limit? Next key picks up the request mid-flight.

attempt=1/14 key=gsk_9KeW... → rate_limit
attempt=2/14 key=gsk_FQC6... → success

Two protocols, one endpoint.

Anthropic Messages and OpenAI Chat Completions are both first-class citizens.

POST /v1/messages → Anthropic format
