  description: "MAAC Go — Taiwan-first self-serve SMS platform. Send transactional (OTP /\norder / reminder) and broadcast SMS with NCC compliance, MAAC delivery\nbackend, and real-time DLR webhooks.\n\n- Base URL: `https://sms.cresclab.com/api`\n- Auth: `Authorization: Bearer <sk_live_... or sk_test_...>`\n- New accounts receive a one-time NT$39 trial credit (50 SMS) on signup, enough to send real test SMS immediately.\n- API keys are scoped and wallet-backed; sending debits the account balance unless your deployment uses a mock SMS/payment adapter.\n- All phone numbers use E.164 (`+886912345678`). 09xxxxxxxx is also accepted.\n- Cost: NT$0.78 per SMS segment (Chinese: 70 chars/segment · English: 160/segment).\n- Rate-limit errors return `429 rate_limited` with limit/used details and retry guidance when available.\n- Delivery confirmations arrive asynchronously via webhook (`sms.delivered`\n  / `sms.failed`); poll `GET /sms/{id}` as a fallback.\n- MCP clients (Claude / Cursor / Windsurf) can use this spec directly, or\n  connect via `POST /api/mcp` (JSON-RPC 2.0) with the same bearer key.\n"

        `consent_source` is required for NCC compliance. Duplicate phones within a batch

        are deduped; existing `(user_id, phone)` pairs are skipped.
