Rate limits

Read-only headroom report. Use to dimension burst sends before they hit the limiter.

{
  "per_customer": { "limit": 60, "remaining": 47, "reset_at": "2026-05-22T15:30:00.000Z" },
  "per_channel": null,
  "per_key": null
}

The endpoint never consumes a token — it's a pure peek. per_channel and per_key report null until the gateway enforces those scopes. The standard 429 / Retry-After response still applies on the request paths.
