Stream an agent response as SSE word chunks
Invoke the agent through the blocking chat path, then emit the finished response word-by-word as Server-Sent Events (~30 ms gaps): token events carrying one word each, a terminal done event with token/cost totals and the conversation id, and an error event on failure. Accepts the same body as POST /agents//chat. Use it when an SDK or UI wants a text/event-stream experience on agent paths where the runtime does not support native token streaming — for runtime-native streaming prefer POST /agents//chat/stream. Rate-limited per tenant (20 req/min shared with the chat pair).

Headers
Stripe-style idempotency token. Pass a stable, client-generated value (1-255 chars) to dedupe retries on transient timeouts. The same key+credential+path replays the original response for 24h on 2xx (5min on 4xx, 30s on 5xx). Returns 409 if a concurrent request with the same key is already in flight; replayed responses include the Idempotency-Replay: true response header.
1 - 255Sandbox opt-in for Clerk-session-authenticated requests. Set to true to route the call through the test-mode pipeline: no real provider delivery, no credits deducted, response meta.test_mode: true. Ignored for live API keys (dv_live_sk_*) — server-to-server clients must use a test-prefixed key (dv_test_sk_*) to exercise sandbox. Test-prefixed keys unconditionally enable sandbox regardless of this header.
