• bulksms_block_number ~177 tokens
  WRITE: adds ONE phone number to the account's blocked list, so that no further messages are sent to it (a send to a blocked number fails with FAILED.BLOCKED and still costs credits). This API has no way to remove a block again: do it only when the user asks for it. BulkSMS REST: POST /blocked-number
• bulksms_get_message ~125 tokens
  Get one sent or received message by its id: body, recipient, delivery status, number of parts and credit cost. BulkSMS REST: GET /messages/{id}.
• bulksms_get_profile ~119 tokens
  Show the BulkSMS account: username, credit balance, credit limit, whether credit transfer is allowed, the daily message quota (size and remaining today) and the sender ids this account may use. Company and billing details are left out. BulkSMS REST: GET /profile.
• bulksms_list_blocked_numbers ~172 tokens

• bulksms_list_webhooks ~116 tokens
  List the account's webhooks (name, trigger SENT/RECEIVED, active flag, invoke option). Only the host of each webhook URL is shown: the path and query can hold a secret. Read-only: webhooks are not changed by this server. BulkSMS REST: GET /webhooks.
