}Estimate an unsaved segment's audience size
Return a FAST (sub-second) APPROXIMATE audience-size estimate for a filter AST using the query planner’s row estimate — no full COUNT scan. Designed to fire on every keystroke in the rule-builder while the exact POST /segments/preview runs in parallel. Returns a 400 INVALID_FILTER when the AST references an unknown field or operator.

Dashboard JWT token from Clerk
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.
true, false Body
The AND/OR filter AST to estimate ({ op, conditions }).
