Convert an image to a carrier-native MMS format (async)
Submit an HTTPS image URL (HEIC, HEIF, BMP, TIFF, or an oversized JPEG/PNG/WebP) to be re-encoded to a carrier-native MMS format and downscaled under the carrier soft cap. Returns 202 with a job_id; poll GET /messages/media/convert/:jobId until status is completed (carrier-native media_url returned) or failed. Images only — video and audio conversion returns 422.

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.
