- **Sandbox-first API surface**: `/v1/messages` (send, get, list, Idempotency-Key
  support), `/v1/numbers` (search, purchase, release), `/v1/lookup` (+`/spam`),
  `/v1/events`, and `POST /v1/test/inbound` for simulating inbound SMS.
- **Self-serve console** at [/console](/console): instant
  free sandbox keys, no card.
- **Live mode** (after live-access review): real number provisioning across 200+
  US/Canada area codes and real SMS delivery.
- **Agent surface**: OpenAPI ([yaml](/api/v1/openapi.yaml) ·
  [json](/api/v1/openapi.json)), `llms.txt`, single-file docs
  (`llms-full.txt`), markdown twins of every docs page, an
  [MCP server](/.well-known/mcp.json), and an agent skill
  ([simplesms](/skills/simplesms/SKILL.md)).

### Known limitations

- Live delivery receipts are not yet emitted; a live message's status stays
  `sent` (sandbox simulates the full lifecycle). Webhook endpoints shipped
