Server tool list (10)
Raw names from tools/list. Only developers need these.
| generate_otp | Send a one-time password (OTP) to a phone number via SMS, WhatsApp, or Telegram. MyOTP.App generates the code, formats the message, picks the best carrier route, and delivers it. Returns a `message_id` (UUID) — keep it; you'll pass it to `verify_otp`, `check_otp_status`, or `extend_otp` later. Each call deducts credits from the account balance; the per-message cost varies by destination country and channel and is returned in the `cost` field. Use this whenever an app needs to verify someone's phone — signup, login 2FA, password reset, transaction confirmation, etc. |
| verify_otp | Verify a code submitted by an end user against the OTP MyOTP delivered. Returns `{status: 'success'}` if the code matches and the OTP hasn't expired — at that point the OTP is consumed and cannot be reused. Returns `{status: 'failed', reason: 'invalid' | 'expired' | 'not found'}` otherwise. You MUST pass either `phone_number` or `message_id` to identify which OTP you're verifying against. Call this after collecting the code from the user (login form, signup screen, etc.). |
| check_otp_status | Check whether a previously sent OTP is still active and (with DLR_ACCESS entitlement on Enterprise plan) get its delivery status. Returns `is_active` (bool) and `expires_at` (ISO timestamp) on every plan. On Enterprise plans, also returns `DLR` (one of 'delivered', 'sent', 'read', 'failed', 'pending'). Useful when an end user reports they didn't receive the code — you can confirm whether MyOTP delivered it before deciding to resend. Does NOT verify a code; use `verify_otp` for that. |
| extend_otp | Extend the expiry time of an active OTP without sending a new one. Useful when the end user is taking longer than expected to enter the code (e.g., switched apps, dealing with carrier delivery delay). Adds `duration` seconds (60-14400) to the current `expires_at`. Requires the EXTEND_OTP entitlement (Business or Enterprise plan). Some destination countries don't allow extensions — the API will return 403 in that case. Cheaper and less spammy than calling `generate_otp` again. |
| get_account_info | Return account details for the API key in use. Always returns at least the account `email`; depending on plan and platform version may also return balance/credit/plan info. Use this as a sanity check when wiring up MyOTP for the first time — if this call succeeds, your API key and IP whitelist are configured correctly. |
| get_usage_report | Fetch a paginated list of OTP transactions for a date range. Each transaction includes message_id, timestamp, phone_number, channel, country, cost, status, and the originating client IP. Date range cannot exceed 31 days. Defaults: last 7 days, page 1, 10 per page. Requires the API_REPORTING entitlement (Business or Enterprise plan). Use this to: audit recent activity, build internal dashboards, reconcile billing, or debug delivery issues across many recipients. |
| create_account | Create a MyOTP.App agent account and return its one-time API key. No API key is required for this tool. The new account starts with zero balance; USDC top-ups work immediately, while card top-ups unlock after a human confirms the email address. |
| get_account_status | Return email verification, balance, plan, and status for the configured MyOTP agent account. Set resend_verification to request another confirmation email first. Unverified accounts can top up with USDC, but cards stay locked. |
| get_topup_quote | Get the live price and payment options for buying MyOTP credits, without making a purchase. Use this when generate_otp or another send fails with HTTP 403 insufficient balance / NoBalance, or before calling `top_up_credits` to show the cost. Returns USDC and card client commands and never exposes the configured API key. |
| top_up_credits | Prepare or complete an autonomous MyOTP credit purchase with USDC or card through Machine Payments Protocol (MPP). Use this when generate_otp or another send fails with HTTP 403 insufficient balance / NoBalance. The tool quotes first, then returns a structured 402 challenge and exact retry details for the agent's own MPP client; if fetch is already wrapped by a credential-carrying MPP runtime, it returns the credited response directly. |
