Dry-run LCR route quote
Simulate the least-cost-routing decision for a destination and estimate the cost you would be charged. Everything is computed against the same scoring engine + scope-match the preflight gate uses: decision='byo' names the carrier that would win (cost $0 — you pay your upstream directly); decision='devotel' returns a Devotel-termination cost estimate off the pricing resolver (unitPriceCents/totalCents), or an explicit devotelQuote: null when pricing couldn’t resolve. The request body is { destination, messageCount } (messageCount defaults to 1). Nothing is billed — the endpoint is read-only and never debits your wallet.

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 destination phone-number string (E.164 like +44... or the short-form you would actually send — the scope-match + price resolver interpret it exactly the way the live send does).
How many messages to price (defaults to 1 so a single-send dry run reads a per-message unit price).

The dry-run quote: the winning carrier (on a byo match), the per-candidate score breakdown, and the Devotel-egress cost estimate when no BYO carrier matched.
