Dry-run a studio graph with one message
Execute a graph in the interpreter against a single input message without persisting a run — the ‘try my canvas’ button in the builder. Body: { "message": "<text>" }. The same structure checks as publish run first (422 with per-issue detail). Graphs containing tool nodes are rejected pre-flight (422) because tool execution only happens on the published agent’s run endpoint; the test-run executes LLM, condition, and response nodes only. Returns per-run metrics — response text, token usage, API-call usage — without touching production traffic. Requires the owner, admin, or developer role.

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.
